mInAsyncPaint is only needed because the code using CreateBuffer expects the
buffer to be locked when it is returned. This isn't necessary because we can
now lock in BeginPaint.

Now that BeginPaintBuffer and BeginPaint are both implemented by content client,
I think it makes sense to just merge them into one method. This simplifies the
interface clients have to use.

This commit does some more cleanup on the content client class hierarchy.
Some methods were virtual or instance methods when they didn't need to be.

CapturedPaintState::mTarget is actually a dual draw target to the black and
white draw targets, so this code will have the white draw target cleared black
and then white. This isn't incorrect, it's just wasteful.

UpdateDestinationFrom actually only uses a rect, so it's best to not be
misleading and force the clients of it to do the conversion.

This could be a part of the previous commit, but I omitted it to keep the size
down. Just some updates to comments and documentation.

This commit is the guts of the refactoring.
This commit removes rotated content buffer, and moves the necessary
functionality to content client. All content clients now do not inherit from
rotated content buffer, but contain a refptr to a rotated buffer.
For the basic content client, this is a DrawTargetRotatedBuffer.
For the remote content client, this is a RemoteRotatedBuffer.
The double buffered content client contains an additional RemoteRotatedBuffer
for the front buffer.
Each derived class of content client only needs to implement a method to
create its own rotated buffer. The rest is handled by the base content
client. The remote content clients still override some additional methods
to sync buffers and do IPC.

Miscellaneous cleanup, PaintState doesn't need to know this as no one uses
this information outside of the content client classes.

The front buffer for a double buffered content client is really just another
rotated buffer, so it can simplify the code to use the class we just added.
The goal is to have the back and the front buffer using remote rotated buffers,
but this is a good first step.
Note: The front buffer is represented as a Maybe<RemoteRotatedBuffer> in this
commit, but in the future it will be a RefPtr. That can't be done yet, because
rotated buffer can't implement refcounting in addition to compositable client.

UpdateDestinationFrom is a useful method for any rotated buffer. This will be
needed when content clients are no longer rotated buffers.
Note: EnsureBuffer and EnsureBufferOnWhite were moved out of
UpdateDestinationFrom because I'd like to kill those methods, and so the calls
were moved to all users of UpdateDestinationFrom.

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.
Currently the profiler mostly uses an array of strings to represent which
features are available and in use. This patch changes the profiler core to use
a uint32_t bitfield, which is a much simpler and faster representation.
(nsProfiler and the profiler add-on still use the array of strings, alas.) The
new ProfilerFeature type defines the values in the bitfield.
One side-effect of this change is that profiler_feature_active() now can be
used to query all features. Previously it was just a subset.
Another side-effect is that profiler_get_available_features() no longer incorrectly
indicates support for Java and stack-walking when they aren't supported. (The
handling of task tracer support is unchanged, because the old code handled it
correctly.)
