Skia: Fix path to OpenGL Headers

The path that Skia was pointing to for the OpenGL Headers
was moved to frameworks/native. This patch will also be
submitted to the mainline for Google.

Change-Id: I75d2ce267d5ec202bb2e5e995f25f9ddfba0dc57
Neon optimized implementation of S16_opaque_D32_nofilter_DX

This patch does the following:
* Neon ASM blitter from RGB565 to ABGR8888 without blend.
* Special case for no scaling but the scaling case is almost as fast.

Assembly optimized 4 blittering related functions:

S32A_D565_Opaque
S32A_Opaque_BlitRow32
nofilter_gether
S32A_Blend_BlitRow32

* S32A_D565_Opaque:

Use neon instructions to optimize BLIT routine which operates on
32-bit source ARGB pixel and 16-bit destination RGB pixel. Here,
we process 16-pixels in an iteration. We use regular (32-bit)
arm instructions when number of pixels is less than 16 or the
architecture doesn't support SIMD/NEON instructions. When alpha
value is 255, this version of BLIT routine performs 35% better
in comparison to S32A_D565_Opaque_neon routine.

* S32A_Opaque_BlitRow32 and nofilter_gether:

Use neon instructions to optimize BlitRow32 and nofilter_gether
functions for 32-bit source and destination pixel arrays. An improvement
of 76% is observed with neon optimized BlitRow32 function and 6%
improvement is observed with nofilter_gether function.

* S32A_Blend_BlitRow32:

Optimize S32A_Blend_BlitRow32 using neon instructions for armv7
based targets and using regular arm instructions for armv6 based
targets.

This is the consolidated commit from several patches.

Two skia optimizations:

1. Combine S16_opaque_D32_nofilter_DX and clampx_nofilter_trans
2. Change MAX_BUF between mproc and sproc to 1024 from 128

Opt 1 is giving about 8-10 FPS in gmail and facebook apk.
Opt 2 is helping all combinations for shaderspan.

skia: Fix a bug in clampx_nofilter_trans_S16_D32_DX

When scaling a line, in the case of the last pixel needing to be
duplicated, the beginning of the line is getting clobbered with wrong
value.  This is because dest buffer pointer is not moved forward.  Fix
that by adding pointer update line.
