This avoids a lot of mismatches between nsAString and char16_t*, thus removing
many getter_Copies() and ToNewUnicode() and get() calls, and generally making
things simpler.
Note: the patch removes GetDefaultPrinterNameFromGlobalPrinters() by simply
inlining it at its two callsites, which is easy with the changed types.

Currently the Gecko Profiler defines a moderate amount of stuff when
MOZ_GECKO_PROFILER is undefined. It also #includes various headers, including
JS ones. This is making it difficult to separate Gecko's media stack for
inclusion in Servo.
This patch greatly simplifies how things are exposed. The starting point is:
- GeckoProfiler.h can be #included unconditionally;
- everything else from the profiler must be guarded by MOZ_GECKO_PROFILER.
In practice this introduces way too many #ifdefs, so the patch loosens it by
adding no-op macros for a number of the most common operations.
The net result is that #ifdefs and macros are used a bit more, but almost
nothing is exposed in non-MOZ_GECKO_PROFILER builds (including
ProfilerMarkerPayload.h and GeckoProfiler.h), and understanding what is exposed
is much simpler than before.
Note also that in BHR, ThreadStackHelper is now entirely absent in
non-MOZ_GECKO_PROFILER builds.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

Add a way to append app notes to the crash report from Java, so we can
associate additional crash data with the crash.

Due to the indeterminate nature of Gecko shutdown, the ref count of the
nsWindow on Android would sometimes go to zero before the XPCOM shutdown
observer was called in nsBaseWindow which is where the compositor thread
IPC is shutdown. If nsBaseWindow::Shutdown does not get called, then the
compositor thread IPC is shutdown in the nsBaseWindow destructor.
Unfortunately while the nsWindow is being deleted, it can be accessed in
the compositor thread and cause a crash in
LayerManagerComposite::RenderToPresentationSurface.
Calling nsBaseWidget::DestroyLayerManager() in nsWindow::Destroy()
ensures it gets called before the destructor gets invoked typically in
the Destroy() call.

Doing this avoids -Wundefined-var-template warnings with clang. This
warning is mostly harmless (clang is trying to tell you a linker error
might be awaiting you later), but being careful with this might make
using C++ modules easier somewhere down the line.
clang seems to think that `Base` is unused despite its obvious uses
inside this class. We can deal with the `Base::` qualifications for
name lookup by using `this->` instead, and the other uses of `Base::`
can simply use the explicit name of the superclass.
This patch refactors the nsThread event queue to clean it up and to make it easier to restructure. The fundamental concepts are as follows:
Each nsThread will have a pointer to a refcounted SynchronizedEventQueue. A SynchronizedEQ takes care of doing the locking and condition variable work when posting and popping events. For the actual storage of events, it delegates to an AbstractEventQueue data structure. It keeps a UniquePtr to the AbstractEventQueue that it uses for storage.
Both SynchronizedEQ and AbstractEventQueue are abstract classes. There is only one concrete implementation of SynchronizedEQ in this patch, which is called ThreadEventQueue. ThreadEventQueue uses locks and condition variables to post and pop events the same way nsThread does. It also encapsulates the functionality that DOM workers need to implement their special event loops (PushEventQueue and PopEventQueue). In later Quantum DOM work, I plan to have another SynchronizedEQ implementation for the main thread, called SchedulerEventQueue. It will have special code for the cooperatively scheduling threads in Quantum DOM.
There are two concrete implementations of AbstractEventQueue in this patch: EventQueue and PrioritizedEventQueue. EventQueue replaces the old nsEventQueue. The other AbstractEventQueue implementation is PrioritizedEventQueue, which uses multiple queues for different event priorities.
The final major piece here is ThreadEventTarget, which splits some of the code for posting events out of nsThread. Eventually, my plan is for multiple cooperatively scheduled nsThreads to be able to share a ThreadEventTarget. In this patch, though, each nsThread has its own ThreadEventTarget. The class's purpose is just to collect some related code together.
One final note: I tried to avoid virtual dispatch overhead as much as possible. Calls to SynchronizedEQ methods do use virtual dispatch, since I plan to use different implementations for different threads with Quantum DOM. But all the calls to EventQueue methods should be non-virtual. Although the methods are declared virtual, all the classes used are final and the concrete classes involved should all be known through templatization.

It wasn't enough to just check for `mWindow` in `OnResumedCompositor()`,
because the `LayerViewSupport` instance itself could have been released.
This patch now checks for both cases.

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.

Use the UI thread's tid for checking if we're on the UI thread in Gecko.
This lets us get rid of `GeckoThread.registerUiThread`, in order to

called.

Right now we throw NullPointerException with the message "Null native
pointer", but we can save the type of the native pointer in the message
to make it easier to categorize and analyze crashes. This patch uses the
__func__ feature to get the name of a particular template parameter
type.

This parameter isn't used by any implementation of onDispatchedEvent,
