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.

Replace it with NS_INTERFACE_MAP_BEGIN_CYCLE_COLLECTION, because it
has been the same for a while.

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.

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.

There are at least four ways XHRMT can error on load.
Let's be specific about it.

With nsIDocument::IsScriptTracking, we know that whether a script is a tracking script. If the XHR is created by a tracking script, we want to lower the priority of the http channel.

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
ignoring any parallelism or overall connection limits.

This patch is to label the runnables dispatched to main thread of the
content process.
The major changes in xhr are to replace DispatchTo{Current,Main}Thread and
replace NS_DispatchToCurrentThread with |mWorkerPrivate->DispatchToMainThread|
in which a DocGroup-specific EventTarget on main thread for worker.
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.
