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.

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.

Users can block the overriding of shortcuts using the permissions tab of the page info dialog, as with other permissions. Site permissions also allows the use of permissions.default.shortcuts to block overriding shortcuts for all sites.

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.

Before if a key input was handled with APZ we wouldn't dispatch it to content,
because it was guaranteed there wouldn't be any key listeners. Now we are
allowing passive key listeners behind a pref, and so we will sometimes handle
a key input in APZ and dispatch it to content. When this happens, XBL shouldn't
do the default action, otherwise we would double scroll.

nsMenuBarListener::KeyPress() is eKeyEvent listener in the system event group. If the target is a remote process, it shouldn't handle accesskey immediately because preceding eKeyDown event may be consumed in the remote process or eKeyPress event itself may be consumed in the remote process.
This patch makes nsMenuBarListener::KeyPress() mark eKeyPress event as "waiting reply from remote process" only when the event matches with a menu item's accesskey and it will be send to a remote process later. Then, reply event should be handled in this method if it's available.

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.

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.

This change avoids lots of false positives for Coverity's CHECKED_RETURN
warning, caused by NS_WARN_IF's current use in both statement-style and
expression-style.
In the case where the code within the NS_WARN_IF has side-effects, I made the
following change.
> NS_WARN_IF(NS_FAILED(FunctionWithSideEffects()));
> -->
> Unused << NS_WARN_IF(NS_FAILED(FunctionWithSideEffects()));
In the case where the code within the NS_WARN_IF lacks side-effects, I made the
following change.
> NS_WARN_IF(!condWithoutSideEffects);
> -->
> NS_WARNING_ASSERTION(condWithoutSideEffects, "msg");
This has two improvements.
- The condition is not evaluated in non-debug builds.
- The sense of the condition is inverted to the familiar "this condition should
be true" sense used in assertions.
A common variation on the side-effect-free case is the following.
> nsresult rv = Fn();
> NS_WARN_IF_(NS_FAILED(rv));
> -->
> DebugOnly<nsresult rv> = Fn();
> NS_WARNING_ASSERTION(NS_SUCCEEDED(rv), "Fn failed");

eKeyDownOnPlugin (mozkeydownonplugin) and eKeyUpOnPlugin (mozkeyuponplugin) should execute if the key combination is reserved by the linked <command> element.
Note that there is no eKeyPressOnPlugin. Therefore, eKeyDownOnPlugin may execute shortcut key handler which is registered as a keypress event handler.

If a plugin process posts native key events to the widget, it needs to check if the key combination is reserved by chrome because if it's reserved by chrome, the reserved shortcut key handler should be executed and the event shouldn't be handled by the focused plugin.
This patches add eKeyDownOnPlugin and eKeyUpOnPlugin. nsXBLWindowKeyHandler will listen to them and handle them as normal keydown and keypress or keyup event. Note that these events won't be fired on content in the default event group and won't be sent to the remote process.
