We rely on mesa/main to tell us whether to update vertex elements.
This decreases overhead for obvious reasons.
The select/feedback code path doesn't use this, which is why you see
unconditional "ALL" in a few codepaths.
This sequence of GL calls doesn't update vertex elements if only
the pointer and stride vary:
glVertexPointer()
glDrawElements()
glVertexPointer()
glDrawElements()
glVertexPointer()
glDrawElements()

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.
Closes: #1905

Previously, ReadPixels, PBO upload/download, and clears would call
cso_save_state with CSO_PAUSE_QUERIES, causing cso_context to call
pipe->set_active_query_state() twice for each operation. This can
potentially cause driver work to enable/disable statistics counters.
But often, there are no queries happening which need to be paused.
By keeping a simple tally of active queries, we can skip this work.

The scissor state -is- setup, but the scissor test is not enabled. This
can prevent certain optimizations from occurring on tilers where
unaffected tiles are thrown out entirely.
v2: Only enable scissor test if the scissor test is actually set by the
app, to avoid regressing quad-based clears used for other reasons (like
a color mask).

The st_vp_uses_current_values() helper is only used in st_context.c
so move it there.
The st_get_active_states() function is only used in st_context.c so

We implement the basic VS and FS, as well as the VS that does layered
clears by writing gl_Layer from the vertex shader. Drivers which need
a geometry shader for writing layer continue falling back to TGSI, as
I didn't need this and so didn't bother implementing it. (We certainly
could, however, if people want to add it in the future.)

For RGB surfaces (for example) we don't really care that the colormask

If we can't clear all the buffers with pctx->clear() (say, for example,
because of ColorMask), push the buffers we *can* clear with pctx->clear()
first. Tilers want to see clears coming before draws to enable fast-
paths, and clearing one of the attachments with a quad-draw first
confuses that logic.

st/mesa doesn't need the draw bounds for draw calls. I've added the call
where it's necessary in core Mesa and drivers, but I suspect that most
drivers can just move the call to the right places.
The core Mesa places aren't hot paths, so the call overhead doesn't matter
there.
For now, only st/mesa is made such that this function is invoked very
rarely.

If a VAO isn't bound and u_vbuf isn't enabled because of the Core profile,
we'll get user vertex buffers in drivers if we update vertex buffers
in glClear. So don't do that.
This fixes a regression since disabling u_vbuf for Core profiles.

DEQP's clear tests like to give us x + w < 0 or y + h < 0. Since we
were comparing to an unsigned, it would get promoted to unsigned and come
out as bignum >= width or height and we would clear the whole fb instead
of none of the fb.
Fixes 10 tests under deqp-gles2/functional/color_clear.
