The renaming here is like this:
SetStringBuffer -> SetKnownLiveStringBuffer
SetEphemeralStringBuffer -> SetStringBuffer
SetOwnedString -> SetKnownLiveString
SetOwnedAtom -> SetKnownLiveAtom
This should make it clearer what the lifetime expectations are on the caller side.

There are several ways that expanded principals can be used as triggering
principals for requests. While that works fine for security checks, it also
sometimes causes them to be inherited, and used as result principals in
contexts where expanded principals aren't allowed.
This patch changes our inheritance behavior so that expanded principals are
downgraded to the most appropriate constituent principal when they would
otherwise be inherited.
The logic for choosing the most appropriate principal is a bit suspect, and
may eventually need to be changed to always select the last whitelist
principal, but I chose it to preserve the current principal downgrade behavior
used by XMLHttpRequest for the time being.

The current API makes the life time and ownership of the result array unclear
without careful reading. The result array is always owned by the principal,
and its lifetime tied to the lifetime of the principal itself. Returning a
const array reference makes this clear, and should prevent callers from
accidentally modifying the returned array.

Currently nsAtom::mString points to the interior of an nsStringBuffer. For
static atoms this requires the use of nsFakeStringBuffer, which is pretty
gross.
This patch changes things so that nsAtom::mString points to a static char
buffer for static atoms. This simplifies a number of things:
- nsFakeStringBuffer and CheckStaticAtomSizes are no longer needed.
- FakeBufferRefCountHelper is no longer needed.
- nsAtom's constructor for static atoms is simpler.
- RegisterStaticAtoms() is simpler.
On the flip-side, a couple of things get more complicated.
- nsAtom::ToString() treats static and dynamic atoms differently.
- nsAtom::GetStringBuffer() is now only valid for dynamic atoms. This
function is only used in two places, both involving DOMString, so those
locations are updated appropriately. This also requires updating some other
code assigning nsStrings to DOMStrings, because we can't assume that
nsStrings are shared.
On Linux64 this change reduces the size of the binary by 8752 B, and moves
81968 B from the .data to the .rodata section, where it can be shared between
processes.

- ensure we don't fire extra events after terminating this way
if a stray OnDataAvailable happens afterward.
2. Ensure that status/statusText correctly return 0/"" to mimic the
spec's "set response to a network error" steps (requires special
handling in the worker XHR code).

XPCOM's string API doesn't have the notion of a "null string". But it does have
the notion of a "void string" (or "voided string"), and that's what these
functions are returning. So the names should reflect that.

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 patch also removes two commented out lines from
editor/composer/nsComposerCommands.cpp, that appear to be related. They are
at top level, where they would never have compiled. They look like
leftovers from some previous change.

Based on XHR spec 6.1, if one or more event listeners are registered on the
associated XMLHttpRequestUpload object, then set upload listener flag.
Therefore, if any event listeners are added after send(), ignore them.
Fire upload.onabort and upload.onloadend when abort() called. Original code
won't fire onabort if mUploadComplete is true.
Per https://xhr.spec.whatwg.org/#request-error-steps xhr.upload.onabort fires before .onabort
This patch makes the following changes to the macros.
- Removes PROFILER_LABEL_FUNC. It's only suitable for use in functions outside
classes, due to PROFILER_FUNCTION_NAME not getting class names, and it was
mostly misused.
- Removes PROFILER_FUNCTION_NAME. It's no longer used, and __func__ is
universally available now anyway.
- Combines the first two string literal arguments of PROFILER_LABEL and
PROFILER_LABEL_DYNAMIC into a single argument. There was no good reason for
them to be separate, and it forced a '::' in the label, which isn't always
appropriate. Also, the meaning of the "name_space" argument was interpreted
in an interesting variety of ways.
- Adds an "AUTO_" prefix to PROFILER_LABEL and PROFILER_LABEL_DYNAMIC, to make
it clearer they construct RAII objects rather than just being function calls.
(I myself have screwed up the scoping because of this in the past.)
- Fills in the 'js::ProfileEntry::Category::' qualifier within the macro, so
the caller doesn't need to. This makes a *lot* more of the uses fit onto a
single line.
The patch also makes the following changes to the macro uses (beyond those
required by the changes described above).
- Fixes a bunch of labels that had gotten out of sync with the name of the
class and/or function that encloses them.
- Removes a useless PROFILER_LABEL use within a trivial scope in
EventStateManager::DispatchMouseOrPointerEvent(). It clearly wasn't serving
any useful purpose. It also serves as extra evidence that the AUTO_ prefix is
a good idea.
- Tweaks DecodePool::SyncRunIf{Preferred,Possible} so that the labelling is
done within them, instead of at their callsites, because that's a more
standard way of doing things.

This function is arguably nicer than calling NS_ProcessNextEvent
manually, is slightly more efficient, and will enable better auditing
for NS_ProcessNextEvent when we do Quantum DOM scheduling changes.
Raise the urgent-start flag in the ClassOfService when the Fetch and XHR are
triggered by user input events. The urgent-start classification will tell the
network requests scheduler to perform it with the highest priority and also

There's an antipattern where nsLiteralString is used as an unnecessary intermediary in converting from CharT* to CharT*,
e.g. CallAFunctionThatTakesACharPointer(NS_LITERAL_CSTRING("foo").get());
or
NS_NAMED_LITERAL_STRING(foo, "abc");
CallAFunctionThatTakesACharPointer(foo.get());
This patch rewrites the callsites that can be trivially changed to use char*/char16_t*.
I'd somewhat like to remove nsTLiteralString::get() altogether, but in code that's less straightforward than these examples, get() is useful enough to keep.
