freedreno: handle null sampler

This is something that XA triggers.  In some cases it will only use
SAMP[1] (composite mask) but not SAMP[0] (composite src).

freedreno/a3xx: missing wfi

RB_FRAME_BUFFER_DIMENSION is not a banked context register, so we need
to wait for the GPU to idle before updating it.  But we'd rather not
have unnecessary WFI's, so actually keep track if we need to emit it or
not.

freedreno/a3xx/compiler: avoid negative register ids

In some cases, we need a register to be assigned up to three components
before the base.  Since we can't have negative register #'s, just shift
everything up.  May increase register usage for trivial shaders, but I
don't think we are shader limited in those cases.  A proper solution is
going to require a better register assignment algorithm (which is on the
TODO list), this is just a hack to get us by until then.

freedreno/a3xx/compiler: fix RECT textures

Whether or not the coords are normalized is handled in the texture

mesa: fix texstore for MESA_FORMAT_R8G8B8A8_SRGB

The case for this was in the wrong function, and this format's store

st: fix st_choose_matching_format to ignore intensity

_mesa_format_matches_format_and_type() returns true for
GL_RED/GL_RED_INTEGER (with an appropriate type) into an intensity
mesa_format.

We want the `red`-based format instead, regardless of the order we find
them in our walk of the mesa formats list.

mesa: Fix format matching checks for GL_INTENSITY* internalformats.

GL_INTENSITY has never been valid as a pixel format -- to get the memcpy
pack/unpack paths, the app needs to specify GL_RED as the pixel format
(or GL_RED_INTEGER for the integer formats).

Note: This was briefly merged before, but exposed some breakage in gallium, so
was reverted. Hopefully it will stick this time.

configure: enable dri3 only for linux

Currently only linux can make use of dri3, so it would make sense to
enable it explicitly for the platform.
Drop a duplicated libudev check while we're at it.

v3: Properly handle dri3 and reword commit message.

Partially revert "automake: allow only shared builds"

Evidently at least static OSMesa is still used as shared one
causes substantial increase in the load time for some programs
that use it (from seconds up-to ~30min).

Rather than forcing everyone to use shared mesa, revert commit
a6efbac9fb502c4f0166e7a0680b6828e1f6926c and default to shared
build when both shared and static are disabled.

v2: Whitespace cleanup, drop silly comment.
