[Glamor] [PATCH v3 0/5] implement all color formats support with GLES2

[Zhigang Gong]

This is the third version of patchset to solve the color formats support
problem with GLES2, and please ignore all the previous patchset. This
patchset is based on the upstream master.

By applying this patchset, glamor can support all the xserver color formats
with GLES2, and my testing shows we can pass rendercheck currently.

And for all the color formats including the 1bpp pixmap, we will handle
the uploading/downloading to/from texture correctly and don't
need to fallback the whole rendering process now.
