This extension just permits GL_UNPACK_ROW_LENGTH, GL_UNPACK_SKIP_ROWS
and GL_UNPACK_SKIP_PIXELS to be passed to glPixelStore on GLES2 so it
is trivial to implement.
Also fixes the usage of GL_IMPLEMENTATION_COLOR_READ_FORMAT_OES,
which may be set to a BGRA format e.g. for a MESA_FORMAT_ARGB8888 fb.

Add support for GL_OES_compressed_ETC1_RGB8_texture to core mesa. There is no
driver support yet.
Unlike desktop GL compressed texture formats, GLES compressed texture formats
usually can only be used with glCompressedTexImage2D. All other gl*Tex*Image*
functions are updated to check for that.

broken in Mesa (e.g., querying GL_TEXTURE_ENV_MODE in OpenGL ES 2.x).

It looks like the only hardware supported by Mesa that cannot do
ARB_texture_env_combine is pre-NV10 NVIDA chips. It appears that
these chips cannot do the GL_SUBTRACT mode. Based on looking at older
copies of nvOpenGLspecs.pdf found on the net, NVIDIA never supported
ARB_texture_env_combine on those chips either.

AFAIK, there are few users of this extension and I can see a couple
reasons why this is probably broken in Mesa anyway.
Reviewed-by: Ian Romanick <ian.d.romanick@intel.com>
Support is removed for four reasons:
1. The implementation was broken with respect to separate blend
equations. The GL_EXT_blend_equation_separate spec says:
"If EXT_blend_logic_op and EXT_blend_equation_separate are both
supported, the logic op blend equation should be supported separately
for RGB and alpha as with the other blend equation modes."
But Mesa's implementation of GL_LOGIC_OP specifically forbids this.
2. No hardware supported by Mesa can support separate blend equations
involving GL_LOGIC_OP.
3. No applications could be found that use this extension.
4. No other Linux OpenGL drivers support this extension.

This was also discussed at XDS 2010. However, actually making the
change was delayed because several drivers still exposed these
extensions to significant benefit (e.g., tdfx). Now that those
drivers have been removed, this code can be removed as well.
