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.
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.

part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

Graphics surface memory usage tracking is done manually, with a global
array containing the number of bytes per each type of surface used.
Since the members of the array can be touched by several different
threads, dynamic race checkers such as TSan complain about To assuage
TSan's sensibilities, we need to use atomics with relaxed memory
consistency; this change generates code identical to what we had before,
but the atomic type assures TSan that it's OK to access members on
multiple threads. We use the relaxed memory consistency to avoid memory
barriers in the generated code.
This makes sense since the file no longer contains anything with the
nsTraceRefcnt name in it, and it will allow renaming nsTraceRefcntImpl
back to nsTraceRefcnt.
