To make PIPE_FORMATs usable from non-gallium parts of Mesa, I want to
move their helpers out of gallium. Since u_format used
util_copy_rect(), I moved that in there, too.
I've put it in a separate directory in util/ because it's a big chunk
of related code, and it's not clear to me whether we might want it as
a separate library from libmesa_util at some point.

Use PIPE_SWIZZLE_* everywhere.
Use X/Y/Z/W/0/1 instead of RED, GREEN, BLUE, ALPHA, ZERO, ONE.
The new enum is called pipe_swizzle.

Now that tiling is in place, we can expose the other formats. Depth is
still broken (need to make changes in the shader), but if you don't expose
it things crash all over. SNORM is dropped, but we could re-add it later
with some shader fixes to handle converting between [0,1] and [-1,1].
