i965/gen7.5: Fix lower bound on number of VS URB entries.

Haswell GT2 and GT3 require the number of vertex shader URB entries to
be at least 64, not 32.

At the moment, we always meet this requirement automatically, because
in the absence of a geometry shader, we assign all available URB space
to the vertex shader.  But when we turn on support for geometry
shaders, this lower limit will become important.

glx: Initialize OpenGL version to 1.0

the default version to be 2.1 instead of 1.2 (minimum required by the
Linux OpenGL ABI).  drisw_glx had a similar error resulting in a default
version of 0.1.

Some driver/card combinations (r200/RV280, i915/915G) don't support
OpenGL 2.1.  These create in some corner cases an indirect context
instead of a direct context when calling glXCreateContextAttribsARB().
This happens because of a bad default value.  To avoid this, just used
the default value specified by the GLX_ARB_create_context specification:

    "The default values for GLX_CONTEXT_MAJOR_VERSION_ARB and
    GLX_CONTEXT_MINOR_VERSION_ARB are 1 and 0 respectively. In this
    case, implementations will typically return the most recent version
    of OpenGL they support which is backwards compatible with OpenGL 1.0
    (e.g. 3.0, 3.1 + GL_ARB_compatibility, or 3.2 compatibility

Refactor all the default value setting to dri2_convert_glx_attribs, and

        "Member declarators may contain precision qualifiers, but may not

So, it sure seems like we shouldn't generate a parse error. :)

Instead of type_specifier, use fully_specified_type in struct members.
However, fully_specified_type allows a lot of other qualifiers that are
not allowed on structure members, so expeclitly disallow them.

Note, this makes struct_declaration look an awful lot like
member_declaration (used for interface blocks).  We may want to
(somehow) unify these rules to reduce code duplication at some point.

i965/gs: Allocate URB space for use by GS.

Previously, we gave all of the URB space (other than the small amount
that is used for push constants) to the vertex shader.  However, when
a geometry shader is active, we need to divide it up between the
vertex and geometry shaders.

The size of the URB entries for the vertex and geometry shaders can
vary dramatically from one shader to the next.  So it doesn't make
sense to simply split the available space in two.  In particular:

- On Ivy Bridge GT1, this would not leave enough space for the worst
  case geometry shader, which requires 64k of URB space.

- Due to hardware-imposed limits on the maximum number of URB entries,
  sometimes a given shader stage will only be capable of using a small
  amount of URB space.  When this happens, it may make sense to
  allocate substantially less than half of the available space to that
  stage.

Our algorithm for dividing space between the two stages is to first
compute (a) the minimum amount of URB space that each stage needs in
order to function properly, and (b) the amount of additional URB space
that each stage "wants" (i.e. that it would be capable of making use
of).  If the total amount of space available is not enough to satisfy
needs + wants, then each stage's "wants" amount is scaled back by the
same factor in order to fit.

When only a vertex shader is active, this algorithm produces
equivalent results to the old algorithm (if the vertex shader stage
can make use of all the available URB space, we assign all the space
to it; if it can't, we let it use as much as it can).

In the future, when we need to support tessellation control and
tessellation evaluation pipeline stages, it should be straightforward
to expand this algorithm to cover them.

radeonsi: simplify and improve flushing

This mimics r600g. The R600_CONTEXT_xxx flags are added to rctx->b.flags
and si_emit_cache_flush emits the packets. That's it. The shared radeon code
tells us when the streamout cache should be flushed, so we have to check
the flags anyway.

There is a new atom "cache_flush", because caches must be flushed *after*
resource descriptors are changed in memory.

Functional changes:

* Write caches are flushed at the end of CS and read caches are flushed
  at its beginning.

* Sampler view states are removed from si_state, they only held the flush
  flags.

* Everytime a shader is changed, the I cache is flushed. Is this needed?
  Due to a hw bug, this also flushes the K cache.

* The WRITE_DATA packet is changed to use TC, which fixes a rendering issue
  in openarena. I'm not sure how TC interacts with CP DMA, but for now it
  seems to work better than any other solution I tried. (BTW CIK allows us
  to use TC for CP DMA.)

* Flush the K cache instead of the texture cache when updating resource
  descriptors (due to a hw bug, this also flushes the I cache).
  I think the K cache flush is correct here, but I'm not sure if the texture
  cache should be flushed too (probably not considering we use TC
  for WRITE_DATA, but we don't use TC for CP DMA).

* The number of resource contexts is decreased to 16. With all of these cache
  changes, 4 doesn't work, but 8 works, which suggests I'm actually doing
  the right thing here and the pipeline isn't drained during flushes.

i965/fs: Detect GRF sources in split_virtual_grfs send-from-GRF code.

It is incorrect to assume that src[0] of a SEND-from-GRF opcode is the
GRF.  For example, FS_OPCODE_UNIFORM_PULL_CONSTANT_LOAD uses src[1] for
the GRF.

To be safe, loop over all the source registers and mark any GRFs.  We
probably won't ever have more than one, but it's simpler to just check
all three rather than attempting to bail early.

Not observed to fix anything yet, but likely to.  Parallels the bug fix
in the previous commit, which actually does fix known failures.
