Prepare for modification of gradient using shader. The
gradient pixmaps now is generated by pixman and we will
replace them with shader. Add structure fields and
dispatch functions which will be needed. Some auxiliary
macro for vertex convert.

Then we don't need to fixup the larger pixmap to the exact
size, just need to let the shader to re-calculate the correct
texture coords.

Some gles2 implementation doesn's support get_proc_address.
And we also need to avoid get those missing functions pointers
when we are GLES2.

We classify the cache according to the texture's format/width/height.
As openGL doesn't allow us to change a texture's format/width/height
after the internal texture object is already allocated, we can't
just calculate the size and then according ths size to put the
fbo to an bucket which is just like SNA does. We can only put
the fbo to the corresponding format/width/height bucket.
This commit only support the exact size match. The following patch
will remove this restriction, just need to handle the repeat/tile
case when the size is not exactly match.
Should use fls instead of ffs when decide the width/height bucket,
thanks for Chris to point this out.

To split a rectangle (0,1,2,3) to two separated triangles need to feed
6 vertices, (0,1,2) and (0,2,3). use glDrawElements can reuse the shared
vertices.

Create a new structure glamor_gl_dispatch to hold all the
gl function's pointer and initialize them at run time ,
rather than use them directly. To do this is to avoid
symbol conflicts.
