The compartment-per-addon code was added so that we could segregate at least
some of the code from system-privileged add-ons into tagged compartments, even
when it ran in browser windows. That allowed us to apply certain special
behavior to them, such as enabling e10s shims, and to track some performance
characteristics.
The only remaining chrome-privileged add-ons now are system add-ons controlled
by us, and the shim system and per-compartment performance metrics are gone,
it no longer serves a purpose.

Unfortunately this means that we need to export a couple more headers, but that
should be ok.
In particular, we have to export some headers that are #included by
nsCSSFrameConstructor.h, because nsCSSFrameConstructor.h itself will now be
included in more places outside of layout/, by .cpp files that don't necessarily
have the ability to indirectly #include its other headers, unless we export
them.

BaseEventFlags::mOnlySystemGroupDispatchInContent was used only when the
key combination is reserved by chrome, and used for preventing to fire
in web content on non-e10s window (bug 1203059).
However, now, this is also used for preventing to fire keypress event for
non-printable key combinations on web contents in the default event group
(bug 1433101). Therefore, now, we need to send events whose
mFlags.mOnlySystemGroupDispatchInContent is true because some event listeners
in the system event group in remote process may want to handle specific
keyboard events before nsXBLWindowKeyHandler.
This patch makes nsXBLWindowKeyHandler::HandleEventOnCaptureInSystemEventGroup()
treat KeyboardEvent whose mFlags.mOnlySystemGroupDispatchInContent is true
but which will be sent to remote process as usual event.

This patch was autogenerated by my decomponents.py
It covers almost every file with the extension js, jsm, html, py,
xhtml, or xul.
It removes blank lines after removed lines, when the removed lines are
preceded by either blank lines or the start of a new block. The "start
of a new block" is defined fairly hackily: either the line starts with
//, ends with */, ends with {, <![CDATA[, """ or '''. The first two
cover comments, the third one covers JS, the fourth covers JS embedded
in XUL, and the final two cover JS embedded in Python. This also
applies if the removed line was the first line of the file.
It covers the pattern matching cases like "var {classes: Cc,
interfaces: Ci, utils: Cu, results: Cr} = Components;". It'll remove
the entire thing if they are all either Ci, Cr, Cc or Cu, or it will
remove the appropriate ones and leave the residue behind. If there's
only one behind, then it will turn it into a normal, non-pattern
matching variable definition. (For instance, "const { classes: Cc,
Constructor: CC, interfaces: Ci, utils: Cu } = Components" becomes
"const CC = Components.Constructor".)

Modifiers of shortcut keys may be same as modifier of content access keys.
When focus is in the main process, such eKeyPress event is sent to remote
content first. Then, and if it's not handled in the remote content,
eAccessKeyNotFound is dispatched into the DOM tree in the main process.
However, nsXBLWindowKeyHandler doesn't handle it as eKeyPress event. So,
it causes that shortcut keys whose modifier conflicts with content access key
won't be handled.
This patch just makes nsXBLWindowKeyHandler treat eAccessKeyNotFound as
eKeyPress event even though other shortcut keys which are handled by JS
won't be executed. Perhaps, we should stop using eAccessKeyNotFound but
it's too risky change for now.

We not only need to care about children getting inserted in the flat tree, but
also about children moving _out_ of the flat tree.
In particular, as of right now we may leave stale data on elements when they
disappear from the flattened tree.
We're lucky enough that in 99% of the situations we enter in[1] and that clears
all the stuff, including servo data. But my assertions for bug 1414999 caught
the template / observes case.
Thus, just clear the whole bound element subtree data, and restyle it in the
end, no need for StyleNewChildren. This matches what we do for shadow DOM
(though in the shadow DOM case we do it async in DestroyFramesForAndRestyle).

This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

With previous change, KeyboardEvent is dispatched even when invisible window
has focus. However, nsRootWindow::GetControllerForCommand() returns controller
for focused window even when the window is invisible because it uses
nsFocusManager::GetFocusedDescendant() to retrieve focused window.
Perhaps, we can assume that users won't expect to do something with invisible
window when they type some keys. Then, nsRootWindow::GetControllerForCommand()
should return controller for visible ancestor window if focused window is
invisible.
This patch makes nsFocusManager::GetFocusedDescendant() can return only visible
descendants. However, it already has a bool argument. Therefore, it should
have a flag instead of adding new flag. Most changes of this patch is replacing
its callers.
Then, nsRootWindow::GetControllerForCommand() and nsRootWindow::GetControllers()
should have a bool flag if it should return controller(s) for visible window.
This patch adds a bool flag for it. Fortunately, the interface isn't scriptable.
Finally, this patch makes nsXBLPrototypeHandler::DispatchXBLCommand() and
EventStateManager::DoContentCommandEvent() retrieve controller for visible
window since they are always handles user input.

There's only one case of sync frame construction from ContentRemoved now, and
it's not on the element being removed, but on the whitespace siblings if needed,
and _only_ when they don't support lazy frame construction.
Basically, this switches all the RecreateFramesForContent calls to use
`aAsyncInsert` (which I changed to an enum class for readability), except when
we're already reframing.
Also, it switches ReframeTextIfNeeded to opt-in into lazy frame construction,
since it's used only when aFlags == CONTENT_REMOVED.
This allows to simplify the DestroyFramesFor API (which I'm happy to rename to
something more meaningful, since now it's something like
DestroyFramesForAndRecreateThemAsync), and do some other consistency cleanups.
A bunch of the ContentRemoved callsites were pretty random at passing
aAsyncInsert, and that was some kind of a mess. This patch ensures consistency,
and makes it impossible to do O(n^2) work when removing DOM nodes, which is
nice.
The underlying reason for this is explained in the description of bug 1377848,
and basically allows us to remove a bunch of Servo hacks on the longer term (a
few of them are going away already, yay!).

Our current machinery for enabling stylo requires a docshell - if there isn't
one, we default to the Gecko style system.
When getComputedStyle operates on an element without a presshell, it uses the
caller's presshell instead. If the element has previously been styled with
one style system (but no longer has a presshell), and the caller uses a
different style backend, using the caller's style system can cause crashes when
we pull bits of cached data off the DOM (like cached style attributes).
So we want to throw when window.getComputedStyle(element) is called for a
(window, element) pair with different style backends (which is what the next
patch in this bug does).
However, that causes a few failures where stylo-backed documents try to do
getComputedStyle on an XHR document (which, without a docshell, will use the
gecko style system).
So this patch does some work to propagate the creator's style backend into
various docshell-less documents. This should allow both chrome (which uses gecko)
and content (which uses stylo) to use getComputedStyle on the response document
for XHRs they create.
Note that the second patch in this bug will make
chromeWin.getComputedStyle(contentObj) throw. If we discover code that does
that, we can just make it invoke the content's getComputedStyle method over Xrays.

This patch replaces four functions of the name AssignWithConversion which
are essentially wrappers around CopyASCIItoUTF16 and LossyCopyUTF16toASCII
with direct calls to the latter two functions. The replaced functions are:
void nsCString::AssignWithConversion( const nsAString& aData )
void nsString::AssignWithConversion( const nsACString& aData )
void nsTString_CharT::AssignWithConversion(
const incompatible_char_type* aData,
int32_t aLength = -1);
The last of the three exists inside the double-included nsTString* world and
so describes two functions, giving four in total.
This has two advantages:
* it removes code
* at the call points, it makes clear (from the replacement name) which
conversion is being carried out. The generic name "AssignWithConversion"
doesn't make that obvious -- one had to infer it from the types.

The issue here is that the DestroyFramesFor call does a ClearServoDataFromSubtree,
and then we subsequently fail to load the bindings, leaving ourselves with an unstyled
subtree that isn't marked with descendant bits and isn't rooted at a display:none element,
which is forbidden. This can trigger crashes when we call the innerText getter on one of
the unstyled elements, since that will first flush layout (which won't find the unstyled
subtree), and then invoke IsOrHasAncestorWithDisplayNone, which passes LazyComputeBehavior::Assert.

The main reason to not do this would be performance (avoiding the
addref/release), but there are two main mitigating factors:
1) All calls to UnwrapReflectorToISupports that pass in a Web IDL object
already do the addref (and in fact QI). So this only affects the
XPCWrappedNative case.
2) The vast majority of the callers proceed to QI on the pointer anyway, and a
second addref is cheap; it's the first addref after a CC that can be
expensive on a cycle-collected object.
Going through the changes one by one:
* In GlobalObject::GetAsSupports, we do have a change that slightly slows down
precisely in the XPCWrappedNative global case. That's the message managers
and the backstagepass. And this really only affects calls to Web IDL statics
from those globals.
* In UnwrapArgImpl we're talking about a Web IDL method taking an "external
interface" type, and the UnwrapReflectorToISupports call is immediately
followed by QI anyway.
* In UnwrapXPConnectImpl we're talking about the case when we have a
non-WebIDL-object implementation of a Web IDL interface. Again, this is the
message manager globals, for EventTarget. And we have a QI call immediately
after the UnwrapReflectorToISupports.
* In the generated HasInstance hook for EventTarget we will be slightly slower
when the LHS of the instanceof is an XPCWrappedNative. And not much slower,
because again there's an immediate QI.
* In InstallXBLField we're never going to have an XPCWrappedNative as thisObj;
it's always an Element in practice. So this is no more expensive than before.
* In sandbox's GetPrincipalOrSOP we now have an extra addref. But it was
followed by various QIs anyway.
* In XPCConvert::JSValToXPCException we have an extra addref if someone throws
an XPCWrappedNative, which is fairly unlikely; our actual Exception objects
are on Web IDL bindings. Plus we have an immediate QI.
* In xpc::HasInstance we have an extra addred if the LHS of instanceof is an
XPCWrappedNative. But, again, there's an immediated QI after the
UnwrapReflectorToISupports.
* In xpcJSWeakReference::Init we are likely doing an extra addref, but again
immediately followed by QI.
I think it's worth making this change just to remove the footgun and that the
perf impact, if any, is pretty minimal.
Most of these changes are just replacements of GetNativeOfWrapper with
UnwrapReflectorToISupports, which is all it did under the hood.
The other changes are as follows:
* In nsDOMClassInfo, we really care whether we have a window, so we can just
UNWRAP_OBJECT to the Window interface, since Window is always on Web IDL
bindings now. Also, the weird compartment check hasn't been needed ever since
GetNativeOfWrapper stopped returning things off the passed-in object's
prototype chain (Firefox 22, bug 658909).
* The only use of do_QueryWrapper was to get a Window in nsDocument; again we
can UNWRAP_OBJECT.
* In XPCJSRuntime, we again just want to check for a Window, so UNWRAP_OBJECT.
Currently, we have 2 bool flags (and optional 2 bool flags with related purpose) for managing propagation state between parent process and remote process. However, it's really complicated. Actually, setting these flags and referring the flags is usually follow explanation.
So, for making simpler, WidgetEvent and BaseEventFlags should have some utility methods for making them as self documented code.
This patch moves WidgetKeyboardEvent::mIsReserved to BaseEventFlags::mIsReservedByChrome. That allows us to manage the cross process event propagation state in same place.

This is a better name for the header that matches its main class.

This commit makes it so we initialize, send, and store a KeyboardMap for every
APZCTreeManager for later keyboard event processing.
This is a naive approach so it may be worth improving.

The XBL bindings used for scrolling are managed by a nsXBLWindowKeyHandler. This
class loads the handlers and has logic for searching through them to match a
keyboard event. This commit adds a KeyboardMap class for storing KeyboardShortcuts
and for mirroring the search logic of nsXBLWindowKeyHandler.

Keyboard scrolling works by first dispatching a key event to the focused element
of the page. It is then caught by a XBL binding put on the chrome event handler of
every window. The XBL binding searches through all of its handlers to find one
that can handle the keyboard event. The matching binding has a command string
which is dispatched to the nsGlobalWindowCommands which dispatches to PresShell
which does the actual scrolling.
To do this asynchronously, we need a representation of the XBL handlers that can
be applied to a KeyboardInput to get a KeyboardAction.
This commit adds KeyboardShortcut for this purpose. KeyboardShortcut is designed
to be compatible with nsXBLPrototypeHandler and to only handle the specific cases
we care about for keyboard scrolling. If a XBL handler runs javascript or does
anything else we cannot handle in an OMT situation, then we create a
dispatch-to-content KeyboardShortcut.
