This moves the gallium interface for clears from using a pointer to 4 floats to a pointer to a union of float/unsigned/int values.
Notes:
1. the value is opaque.
2. only when the value is used should it be interpretered according to
the surface format it is going to be used with.
3. float clears on integer buffers and vice-versa are undefined.
v2: fixed up vega and graw, dropped hunks that shouldn't have been in
patch.

more consistent with rest of gallium naming conventions.
Also rename driver-internal names for these the same.

The util blit functions change their interface (apart from some rename) too
(in particular util_blit_pixels now also takes a pipe_resource as the src blit
argument instead of a surface, as it might just call resource_copy_region).
Maybe the blit util code might need a bit more cleanup, it still doesn't feel
very clean. In particular it seems that util_blit_pixels_tex should probably
disappear, and I think it would be great if the code called by drivers for
blitting (u_blitter.c, which isn't really touched by this change) could somehow
be merged with the u_blit code.

This is a better place than in u_rect.c

use pointer to union instead of void pointer.
gcc complained a lot, depending what the pointer originally actually was.
Looks like it's in fact maybe legal to cast for instance uint pointers to
union pointers as long as union contains a uint type, hence use this with some
callers, other just use union util_color in the first place.

Uf. Lots of files touched. Would people with working vega, xorg, dri1, etc.
please make sure you are not broken, and fix yourself up if you are.
There were only two or three places where the code did not have painful
fallbacks, so I would advise st maintainers to find less painful workarounds,
or consider overhauling util_surface_copy and util_surface_fill.
Per ymanton, darktama, and Dr_Jakob's suggestions, clear has been left as-is.
I will not add PIPE_CAP_BLITTER unless it is deemed necessary.

Only allows clearing currently bound buffers, but colour and depth/stencil in
a single call.
