nsXPIDLStrings are marked as VOIDED upon initialization. Most of these local
nsXPIDLString variables are immediately set via getter_Copies(), which will
either assign a string value (using Adopt()) or do SetIsVoid(). These can be
trivially converted to nsString, which will get the same treatment.
The patch suitably converts the remaining nsXPIDLString local variable as well.

This removes about 2/3 of the occurrences of nsXPIDLString in the tree. The
places where nsXPIDLStrings are null-checked are replaced with |rv| checks.
The patch also removes a couple of unused declarations from
nsIStringBundle.idl.
Note that nsStringBundle::GetStringFromNameHelper() was merged into
GetStringFromName(), because they both would have had the same signature.

Although this is only known to affect buttons with builtin child widgets, it
is difficult to audit all GTK widgets for similar situations, and so the same
defense is applied to all widgets.

To make the HeadlessCompositorWidget work under Windows as well as Linux, I had
to change the way that I hooked it into the existing CompositorWidget system.
Under GTK, the CompositorWidgetInitData and CompositorWidgetDelegate types
provided the information needed by the headless compositor widget already (the
widget client size). On Windows, however, the definitions of these types
differ, and the client size information is simply retrieved from the platform
APIs when needed.
After this patch, CompositorWidgetDelegate is renamed to
PlatformCompositorWidgetDelegate, and a new base class called
CompositorWidgetDelegate is added with "AsPlatformSpecificDelegate()" and
"AsHeadlessCompositorWidget()" methods. In non-headless mode, widgets use
AsPlatformSpecificDelegate() to access the Windows- and GTK-specific delegate
APIs. In headless mode, AsHeadlessCompositorWidget() is used to access the
singular CompositorWidget implementation for headless. Meanwhile, the
CompositorWidgetInitData IPDL type is made into a union which always contains a
headless-specific HeadlessCompositorWidgetInitData struct and under GTK and
Windows also contains an {X11,Win}CompositorWidgetInitData struct.
This also includes a small patch to ensure that the GPU process and
hardware-accelerated compositing are always disabled under headless mode. These
features weren't activated by default in the Linux environments I tested in, but
did end up activating (and then promptly crashing Firefox) when I tested on
Windows.

This fixes a series of issues uncovered by the Web Platform Tests.
The most immediately noticeable symptom was that, during shutdown, PuppetWidgets
on the client side attempted to delete shadow layers that were never created on
the compositor side. The usage of BasicLayerManager in all other widgets due to
headless mode meant that the PLayerTransactionParent was never initialized with
a layer manager, and thus discarded all transaction messages it received but not
delete layer messages.
The effects of only using BasicLayerManager in headless mode also showed up in
the web platform reftests, which ended up as blank white boxes in e10s mode as
the compositor thread never received paint instructions. Switching over to
using ClientLayerManager in headless mode causes these paint instructions to be
relayed.
In order to make ClientLayerManager work under headless mode, it was necessary
to implement a HeadlessCompositorWidget and hook that up to the CompositorWidget
creation function in widget/gtk. A follow-up patch will be necessary to hook up
the same for the other supported widget platforms.

When aEvent.mNativeKeyEvent of nsWindow::GetEditCommandsRemapped() is nullptr, that means the event was created without a native event. Typically, chrome script created the event. In such case, we should not execute native key bindings because doing it exposes the OS settings to chrome script because that might cause some privacy issue. Therefore, the method should do nothing with such event.

Most of the names passed to nsIStringBundle::{Get,Format}StringFromUTF8Name
have one of the two following forms:
- a 16-bit C string literal, which is then converted to an 8-bit string in
order for the lookup to occur;
- an 8-bit C string literal converted to a 16-bit string, which is then
converted back to an 8-bit string in order for the lookup to occur.
This patch introduces and uses alternative methods that can take an 8-bit C
string literal, which requires changing some signatures in other methods and
functions. It replaces all C++ uses of the old methods.
The patch also changes the existing {Get,Format}StringFromName() methods so
they take an AUTF8String argument for the name instead of a wstring, because
that's nicer for JS code.
Even though there is a method for C++ code and a different one for JS code,
|binaryname| is used so that the existing method names can be used for the
common case in both languages.
The change reduces the number of NS_ConvertUTF8toUTF16 and
NS_ConvertUTF16toUTF8 conversions while running Speedometer v2 from ~270,000 to
~160,000. (Most of these conversions involved the string
"deprecatedReferrerDirective" in nsCSPParser.cpp.)

When you start new composition during converting with Mozc in e10s mode, the following things occur:
1. Mozc commits previous composition.
2. Gecko dispatches eCompositionCommit event.
3. Mozc sets new composition string (skipping composition start signal).
4. Gecko dispatches eCompositionStart and eCompositionChange event.
5. Selection is changed asynchronously.
6. Gecko sets position of IME windows.
At #4, Gecko stores start of composition as selection start, then, trying to adjust it at #5. However, new selection is caret position in new composition string. Therefore, it's not used for the adjustment. This causes that stored composition start offset is always the start of the previous composition (if the previous patch didn't change EnsureToCacheSelection() behavior). So, IMContextWrapper needs to compute proper composition start offset in this case.
The simplest fix is, modifying selection at #2 as which will be occurred in focused editor. So, this patch makes the selection cache collapsed to the end of committing string.
Note that actual selection may be different if JS changes selection and/or the text in the focused editor. However, it doesn't matter. IMContextWrapper should behave as expected while current composition is active.

IMContextWrapper::EnsureToCacheSelection() always queries actual selection when the caller needs selected string. However, this may be expensive and this is bad behavior for the following patch because it wants to emulate selection range until receiving next selection change notification.
Therefore, this patch makes IMContextWrapper::Selection store selected string instead of just its length like other native IME handlers
Additionally, this patch renames IMContextWrapper::mSelectedString to IMContextWrapper::mSelectedStringRemovedByComposition for making the difference between it and the new string in Selection clearer.

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 refactors the two nearly-identical callsites into a method so that
I can do caching in that method in the next patch.
Note that there was a slight difference between them in that the
aWidgetFlags parameter to GetGtkWidgetAndState was only passed from one
callsite. However, given that the aState parameter is null, this
doesn't cause any behavior differences. (Some controls in
GetGtkWidgetAndState null-check aWidgetFlags and some don't!)
Note also that this makes it always assign a result (often zero). This
is fine for both callsites; GetWidgetPadding previously assigned zero
right before the call, and GetWidgetBorder did so at the start of the
function (and wasn't modified in between, since it was immediately
before the switch that the modified code is a case in).
