mesa: increase MAX_UNIFORMS to 1024 (of vec4 type)
Old limit was 256. Note that no arrays are declared to this size.
The only place we have to be careful about raising this limit is the
prog_src/dst_register Index bitfields. These have been bumped up too.
Added assertions to check we don't exceed the bitfield in the future too.
