Without this, we're left with a bunch of medium-precision residue, like
i2imp. And to avoid that the lowering intrudces left-over instructions,
also run other lowering passes, similar to what other drivers do.

If the calling process happens to use an invalid bo (e.g. fd has been
closed), this led to lseek() returning -1 and this mmap trying to mmap
a buffer of size -1 (0xffffffffffffffff ...) which led to mmap
failing, which led to munmap failing which then led to the process
aborting.
This fixes that to gracefully handle the mmap failures and percolate
the failures back up through the API so eglCreateImage will not return
a valid image anymore, thus the error is detectable in the caller
process too.

gallium hud checks for the PIPE_FORMAT_B8G8R8A8_SRGB format to set
has_srgb, but can then receive a different format such as
PIPE_FORMAT_B8G8R8X8 in hud_run.
If the driver supports PIPE_FORMAT_B8G8R8A8_SRGB but does not support
the other formats such as PIPE_FORMAT_B8G8R8X8_SRGB, that will break
rendering as gallium hud assumes srgb is also supported for that format.
Extend the check to set has_srgb to prevent that from happening.

gallium hud uses different tgsi fragment shaders for text and background
quads, which have different varying layouts. Since these are compiled
directly from tgsi they bypass some optimizations and may not work
properly on all backends.
A simple fix for the varying layout problem is to define a vs_text
shader to match the varyings in fs_text so the problem is avoided.

A fragment shader that forgets to write to one of the bound render

Since we can handle arbitrary offsets in the load_ubo paths, we can let
the GLSL compiler pack UBO 0 tighter, saving uniform uploads. This may
cause some straddling loads that could reduce performance for vec3s, but
those are rare in shader-db and we expect this to be outweighed by the
wins for normal float/vec2 packing.
