Support RGBA fonts and bitmap fonts (and RGBA bitmap fonts)
Quite a few things going on in this commit:
- Enable bitmap strikes by default in Paint objects.
The SkPaint parameter that enables bitmap strikes was not previously
included in DEFAULT_PAINT_FLAGS. This effectively disabled bitmap
fonts. Oops! It's for the best, though, as additional work was needed
in Skia to make bitmap fonts work anyway.
- Complain if TEXTURE_BORDER_SIZE is not 1.
Our glyph cache code does not currently handle any value other than 1
here, including zero. I've added a little C preprocessor check to
prevent future engineers (including especially future-me) from
thinking that they can change this value without updating the related
code.
- Add GL_RGBA support to hwui's FontRenderer and friends
This also happened to involve some refactoring for convenience and
cleanliness.

Share Caches' index buffer with FontRenderer
This reduces state changes when we draw 9patches and text together,
which happens *a lot*. Also disable the NV profiling extension by
default since it doesn't play nice with display lists deferrals.
To enable it set debug.hwui.nv_profiling to true.

Introduce PixelBuffer API to enable PBOs
PBOs (Pixel Buffer Objects) can be used on OpenGL ES 3.0 to perform
asynchronous texture uploads to free up the CPU. This change does not
enable the use of PBOs unless a specific property is set (Adreno drivers
have issues with PBOs at the moment, Mali drivers work just fine.)
This change also cleans up Font/FontRenderer a little bit and improves
performance of drop shadows generations by using memcpy() instead of
a manual byte-by-byte copy.
On GL ES 2.0 devices, or when PBOs are disabled, a PixelBuffer instance
behaves like a simple byte array. The extra APIs introduced for PBOs
(map/unmap and bind/unbind) are pretty much no-ops for CPU pixel
buffers and won't introduce any significant overhead.
This change also fixes a bug with text drop shadows: if the drop
shadow is larger than the max texture size, the renderer would leave
the GL context in a bad state and generate 0x501 errors. This change
simply skips drop shadows if they are too large.

First OpenGL ES 3.0 based optimization
This change uses a new OpenGL ES 3.0 feature to upload less data when
the font cache needs to be update. This can result in significant
performance improvements on device with large textures or with locales
that use a lot of glyphs (CJK for instance.)
This change also fixes various unpack alignment issues. The unpack
alignment, as well as the unpack row length, is not texture specific
but a global state that affect all glTex/SubImage2D calls. Some of
them were missing the appropriate glPixelStorei() call. This could
result in corrupted textures.

Reduce number of glDraw calls when drawing text
This change moves the mesh buffer from FontRenderer to CacheTexture
to help reduce the number of texture binds and glDraw calls when
drawing text that spans across multiple textures.

Optimize glyph cache texture uploads
Only upload the changed area of the glyph cache, not the entire
bitmap. Note that we can't do the full-on optimization here of copying a sub-rect
of the bitmap because of GL ES 2 limitations, but we can at least copy the
horizontal stripe containing the dirty rect, which can still be a big
savings over uploading the entire bitmap.

in the font/ folder. This will make the code easier to read and
maintain.
