This partially reverts commit d41f5396f3cb619729021390c273f838d92f11fb.

glx: Fix indirect multi-texture GL_DOUBLE coordinate arrays.

There is no draw arrays protocol support for multi-texture coordinate
arrays, so it is implemented by sending batches of immediate mode
commands from emit_element_none in indirect_vertex_array.c.  This sends
the target texture unit (which has been previously setup in the
array_state header field), followed by the texture coordinates.  But for
GL_DOUBLE coordinates the texture unit must be sent *after* the texture
coordinates. This is documented in the glx protocol description, and can
also be seen in the indirect.c immediate mode commands generated from
gl_API.xml. Sending the target texture unit in the wrong place can crash
the remote X server.

To fix this required some more extensive changes to
indirect_vertex_array.c and indirect_vertex_array_priv.h, in order to
remove the texture unit value out of the array_state "header" field, and
send it separately.

glx: Call __glXInitVertexArrayState() with a usable gc.

For each indirect context the indirect vertex array state must be initialised
by __glXInitVertexArrayState in indirect_vertex_array.c.  As noted in the
routine header it requires that the glx context has been setup prior to the
call, in order to test the server version and extensions.

Currently __glXInitVertexArrayState is called from indirect_bind_context in
indirect_glx.c, as follows:

   state = gc->client_state_private;
   if (state->array_state == NULL) {
      glGetString(GL_EXTENSIONS);
      glGetString(GL_VERSION);
      __glXInitVertexArrayState(gc);
   }

But, the gc context is not yet usable at this stage, so the server queries
fail, and __glXInitVertexArrayState is called without the server version and
extension information it needs.  This breaks multi-texturing as
glXInitVertexArrayState doesn't get GL_MAX_TEXTURE_UNITS.  It probably also
breaks setup of other arrays: fog, secondary colour, vertex attributes.

To fix this I have moved the call to __glXInitVertexArrayState to the end of
MakeContextCurrent in glxcurrent.c, where the glx context is usable.

Fixes a regression caused by commit 4fbdde889c. Fixes ARB_vertex_program
usage in the arbvparray Mesa demo when run with indirect GLX and also
the tex-skipped-unit piglit test when run with indirect GLX.

radeonsi: explicitly choose center locations for 1xAA on Polaris

Unlike SC, the small primitive filter does not automatically use center
locations in 1xAA mode, so this is needed to avoid artifacts caused by
the small primitive filter discarding triangles that it shouldn't.

As a side effect of how the effective number of samples is now calculated,
this patch also avoids submitting the sample locations for line/poly smoothing
when they're not really needed.

i965: Fix remaining flush vs invalidate race conditions in brw_emit_pipe_control_flush.

This hardware race condition has caused problems several times already
(see "i965: Fix cache pollution race during L3 partitioning set-up.",
"i965: Fix brw_render_cache_set_check_flush's PIPE_CONTROLs." and
"i965: intel_texture_barrier reimplemented").  The problem is that
whenever we attempt to both flush and invalidate multiple caches with
a single pipe control command the flush and invalidation happen in
reverse order, so the contents flushed from the R/W caches aren't
guaranteed to become visible from the invalidated caches after the
PIPE_CONTROL command completes execution if some concurrent rendering
workload happened to pollute any of the invalidated R/O caches in the
short window of time between the invalidation and flush.

This makes sure that brw_emit_pipe_control_flush() has the effect
expected by most callers of making the contents flushed from any R/W
caches visible from the invalidated R/O caches.
