gallivm: correct channel shift logic on big endian

lp_build_fetch_rgba_soa fetches a texel from a texture.
Part of that process involves first gathering the element
together from memory into a packed format, and then breaking
out the individual color channels into separate, parallel
arrays.

The code fails to account for endianess when reading the packed

the packed values are read on big endian systems.

i965: Always flush caches after blitting to a GL buffer object.

When we blit data into a buffer object, we may need to invalidate any
caches that might contain stale data, so the new data becomes visible.

For example, if the buffer object is bound as a vertex buffer, we need
to invalidate the vertex fetch cache.

While this flushing was missing, it usually happened implicitly for
non-obvious reasons: we're usually on the render ring, and calling
intel_emit_linear_blit() would require switching to the BLT ring,
causing an implicit flush.  This likely provoked the kernel to do
PIPE_CONTROLs on our behalf.  Although, Gen4-5 wouldn't have this
behavior.  At any rate, we should do it ourselves.

    c) Add the new interface in vbtl to set the retrieve fence

    b) The retrieve fd is for all the platform but not just Android
    c) Add a uniform dri2 interface to initialize the surface.

v4.1: a) make some changes of variable name.
      b) the patch is broken into two patches.

v4.2: a) Add a deinit interface for surface to clear the out fence

v5: a) Add enable_out_fence to init, platform sets it true or
       false
    b) Change get fd to update fd and check for fence
    c) Commit description updated

v6: a) Heading and commit description updated
    b) enable_out_fence is set only if fence is supported
    c) Review comments on function names
    d) Test with standalone patch, resolves the bug

v6.1: Check for old display fence reverted

anv/queue: Allow temporary import of SYNC_FD semaphores

We didn't allow them before because it didn't look like the spec allowed
it.  It certainly doesn't make much sense.  However, there are CTS tests
that apparently hit this.  What the spec actually says is:

    "Importing a payload using handle types with copy transference
    creates a duplicate copy of the payload at the time of import, but
    makes no further reference to it. Fence signaling, waiting, and
    resetting operations performed on the target of copy imports must
    not affect any other fence or payload."

A SYNC_FD has copy transference but the import may be temporary or
permanent.  If you do a permanent import of something with copy
transference, I guess it's supposed to work and end up resetting the
permanent state.  In any case, there seems to be no real harm in
allowing it, so why not.
