gallium: Add PIPE_BARRIER_UPDATE_BUFFER and UPDATE_TEXTURE bits.
The glMemoryBarrier() function makes shader memory stores ordered with
respect to things specified by the given bits. Until now, st/mesa has
ignored GL_TEXTURE_UPDATE_BARRIER_BIT and GL_BUFFER_UPDATE_BARRIER_BIT,
saying that drivers should implicitly perform the needed flushing.
This seems like a pretty big assumption to make. Instead, this commit
opts to translate them to new PIPE_BARRIER bits, and adjusts existing
drivers to continue ignoring them (preserving the current behavior).
The i965 driver performs actions on these memory barriers. Shader
memory stores go through a "data cache" which is separate from the
render cache and other read caches (like the texture cache). All
memory barriers need to flush the data cache (to ensure shader memory
stores are visible), and possibly invalidate read caches (to ensure
stale data is no longer visible). The driver implicitly flushes for
most caches, but not for data cache, since ARB_shader_image_load_store
introduced MemoryBarrier() precisely to order these explicitly.
I would like to follow i965's approach in iris, flushing the data cache
on any MemoryBarrier() call, so I need st/mesa to actually call the
pipe->memory_barrier() callback.
Fixes KHR-GL45.shader_image_load_store.advanced-sync-textureUpdate
and Piglit's spec/arb_shader_image_load_store/host-mem-barrier on
the iris driver.
Roland said this looks reasonable to him.

Revert "glsl: relax input->output validation for SSO programs"
This reverts commit
1aa5738e666a9534c7e5b46f077327e6d647c64f.
This patch incorrectly asumed that for SSOs no inner interface
matching check was needed.
From the ARB_separate_shader_objects spec v.25:
" With separable program objects, interfaces between shader stages
may involve the outputs from one program object and the inputs
from a second program object. For such interfaces, it is not
possible to detect mismatches at link time, because the programs
are linked separately. When each such program is linked, all
inputs or outputs interfacing with another program stage are
treated as active. The linker will generate an executable that
assumes the presence of a compatible program on the other side of
the interface. If a mismatch between programs occurs, no GL error
will be generated, but some or all of the inputs on the interface
will be undefined."
This completes the fix from commit:

glsl/linker: always validate explicit location among inputs
Outputs are always validated when having explicit locations and we
were trusting its outcome to catch similar problems with the inputs
since, in case of having undefined outputs for existing inputs, we
would be already reporting a linker error.
However, consider this case:
" Shader stage n:

layout(location = 0) out float a;
...
Shader stage n+1:
-----------------
...
layout(location = 0) in float b;
layout(location = 0) in float c;

aliasing is happening for the inputs.
Therefore, we also need to validate the inputs independently from the
outcome of the outputs validation.

panfrost: Rewrite varying assembly
There are two stages to varying assembly in the command stream: creating
the varying buffers in the command stream, and creating the varying meta
descriptors (also in the command stream) linked to the aforementioned
buffers. The previous code for this was ad hoc and brittle, making some
invalid assumptions causing unmaintainable workarounds to pile up across
the driver (both compiler and command stream side).
This patch completely rewrites the varying assembly code. There's a
trivial performance penalty (we now memcpy the varying meta to the
command stream on draw, rather than on compile). That said, the
improvement in flexibility and clarity is well-worth it.
The motivator for these changes was support for gl_PointCoord (and
eventually point sprites for legacy GL), which was impossible to
implement with the old varying assembly code. With the new refactor,
it's super easy; support for gl_PointCoord is included with this patch.

st/mesa: implement "zombie" sampler views (v2)
When st_texture_release_all_sampler_views() is called the texture may
have sampler views belonging to several contexts. If we unreference a
sampler view and its refcount hits zero, we need to be sure to destroy
the sampler view with the same context which created it.
This was not the case with the previous code which used
pipe_sampler_view_release(). That function could end up freeing a
sampler view with a context different than the one which created it.
In the case of the VMware svga driver, we detected this but leaked the
sampler view. This led to a crash with google-chrome when the kernel
module had too many sampler views. VMware bug
2274734.
Alternately, if we try to delete a sampler view with the correct
context, we may be "reaching into" a context which is active on
another thread. That's not safe.
To fix these issues this patch adds a per-context list of "zombie"
sampler views. These are views which are to be freed at some point
when the context is active. Other contexts may safely add sampler
views to the zombie list at any time (it's mutex protected). This
avoids the context/view ownership mix-ups we had before.
Tested with: google-chrome, google earth, Redway3D Watch/Turbine demos
a few Linux games. If anyone can recomment some other multi-threaded,
multi-context GL apps to test, please let me know.
v2: avoid potential race issue by always adding sampler views to the
zombie list if the view's context doesn't match the current context,
ignoring the refcount.

docs: separate information for compiler selection and compiler options
Split up the "Environment Variables" section into "Compiler Options"
and "Compiler Specification". I think this makes the information
easier to find and understand.
