moz_posix_memalign is a wrapper for posix_memalign that only exists if
posix_memalign exists.
On OSX, it has a fallback for an under-specified bug where it
purportedly returns a pointer that doesn't have the requested alignment.
That fallback was added in bug 414946, over 6 years ago, before jemalloc
was even enabled on OSX.
Considering posix_memalign is used directly in many other places in
Gecko, that we almost always use mozjemalloc, which doesn't have these
problems, and that in all likeliness, the bug was in some old version of
OSX that is not supported anymore, the fallback does not seem all that
useful.
So, just use posix_memalign directly.

This patch:
- Makes the following substitutions (plus necessary namespace qualifiers:
gfxImageFormat::ARGB32 --> SurfaceFormat::A8R8G8B8_UINT32
gfxImageFormat::RGB24 --> SurfaceFormat::X8R8G8B8_UINT32
gfxImageFormat::A8 --> SurfaceFormat::A8
gfxImageFormat::RGB16_565 --> SurfaceFormat::R5G6B5_UINT16
gfxImageFormat::Unknown --> SurfaceFormat::UNKNOWN
- Changes gfxImageFormat to be a typedef to gfx::SurfaceFormat. This will be
removed soon.
- Removes gfxCairoFormatToImageFormat() and gfxImageFormatToCairoFormat() and
replace calls to them with CairoFormatToGfxFormat() and
GfxFormatToCairoFormat().
- Removes ParamTraits<gfxImageFormat>.
- Add namespace qualifiers to SurfaceFormat instances where necessary.

This value is never written anywhere, so it's not needed, and gfx::Surface
doesn't have an equivalent.

cairo_format_t and gfxImageFormat have their equivalent constants in the same
order, so you can just cast between them, which is kind of nasty.
This patch replaces all such casts with explicit conversions via calls to new
conversion functions. These functions will be removed in a subsequent patch.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

This commit was generated using the following script, executed at the

# Don't modify select files in mfbt/ because it's not worth trying to

This conversion was done with the script:
find . -name '*.cpp' -o -name '*.h' -o -name '*.mm' -o -name '*.idl' | \
egrep -v 'cairo-win32-refptr.h|RefPtr.h|TestRefPtr.cpp' | \
xargs sed -i -e 's/mozilla::TemporaryRef</already_AddRefed</g' \
-e 's/TemporaryRef</already_AddRefed</g'
Manual fixups were performed in the following instances:
- We handled mfbt/RefPtr.h manually so as to not convert TemporaryRef itself
into already_AddRefed.
- The following files had explicit Move() calls added to make up for the lack
of a copy constructor on already_AddRefed:
dom/base/ImageEncoder.cpp
dom/media/MediaTaskQueue.{h,cpp}
dom/media/webaudio/PannerNode.cpp
- A redundant overload for MediaTaskQueue::Dispatch was deleted.
- A few manual fixups were required in mfbt/tests/TestRefPtr.cpp.
- Comments, using declarations, and forward declarations relating to
TemporaryRef in dom/canvas/ and gfx/layers/ were changed to refer to
already_AddRefed.
The distinction between moz_malloc/moz_free and malloc/free is not
interesting. We are inconsistent in our use of one or the other, and
I wouldn't be surprised if we are mixing them anyways.
