Adds PIPE_CAP_PRIMITIVE_RESTART_FIXED_INDEX which is a subset of the
primitive restart cap for when the hardware can only support the fixed
indices specified in GLES.

The switch statements were automatically modified with this command:

find \( \( -name \*.cpp -o -name \*.c \) \! -type l \) \
 -exec sed -i -r \
 's/^(\s*case\s+PIPE_CAP_PRIMITIVE_RESTART)\s*:.*$/\0\n\1_FIXED_INDEX:/' \
 {} \;

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.

This is a relatively minimal change to adjust all the gallium interfaces
to use bool instead of boolean. I tried to avoid making unrelated
changes inside of drivers to flip boolean -> bool to reduce the risk of
regressions (the compiler will much more easily allow "dirty" values
inside a char-based boolean than a C99 _Bool).

This has been build-tested on amd64 with:

PIPE_CAP_SM3 has always been an odd one out of all our caps. While most
other caps are fine-grained and single-purpose, this cap encode several
features in one. And since OpenGL cares more about single features, it'd
be nice to get rid of this one.

As it turns, this is now relatively simple. We only really care about
three features using this cap, and those already got their own caps. So
we can remove it, and make sure all current drivers just give the same
response to all of them.

The only place we *really* care about SM3 is in nine, and there we can
instead just re-construct the information based on the finer-grained
caps. This avoids DX9 semantics from needlessly leaking into all of the
drivers, most of who doesn't care a whole lot about DX9 specifically.

TGSI's FBFETCH instruction currently only supports reading from a single
render target, but NIR intrinsics can support multiple render targets.

radeonsi can only support fetching from RT 0, but other drivers may be
able to support fetching from any render target.

To express this, this patch renames PIPE_CAP_TGSI_FS_FBFETCH to simply
PIPE_CAP_FBFETCH, and converts it from a boolean "is FBFETCH supported?"
to an integer number of render targets which can be fetched.

This commit adds a new PIPE_CAP_TEXTURE_MIRROR_CLAMP_TO_EDGE bit,
changes the extension enable to be based on that, and enables it
in all upstream drivers which supported PIPE_CAP_TEXTURE_MIRROR_CLAMP
(so they continue supporting this mode).
