Aggressively unbind GL_PIXEL_UNPACK_BUFFER
Bug: 27186019
Theory: It appears to be possible for FontRenderer
to not unbind its PBO prior to textures being uploaded,
resulting in trying to glSubTexImage2D with a bound
GL_PIXEL_UNPACK_BUFFER. In that scenario the void* is
the offset into the PBO which given a non-null data
will almost certainly overrun the end of the buffer. This
in turn produces a GL_INVALID_OPERATION error.
Change PixelBuffer to avoid leaking this state for now.
This will result in more calls to glBindBuffer/glUnbindBuffer
in the worst case, but the worst case is already bad so this
shouldn't be a problem. In the normal case we avoid binding
the PBO at all ever, so this doesn't impact that.

Normalize GL_UNPACK_ALIGNMENT
Several places were setting GL_UNPACK_ALIGNMENT
unneccessarily, whereas other places were assuming an
unpack alignment of 1. Since we never actually
do explicit row-alignment, set GL_UNPACK_ALIGNMENT
to 1 at context creation time and never change it
Bug: 26584230
Also turns on aggressive glGetError checking to
better catch potential problem zones

Fixes for 64bit in libhwui
Using reinterpret_cast allows conversions between pointer types
and integers which don't have the same size. The corresponding
flags is -Wint-to-pointer-cast.

Batch 9-patches in a single mesh whenever possible
This change also fixes the way batched bitmaps were handled
inside a layer. The layer is now correctly dirtied to minimize
the amount of pixels to blend.
Fix alpha, mode and opaque computations for DrawPatchOp.

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.
