This workaround is documented in the 3DSTATE_GS documentation. It
appears to only apply to early steppings of Broadwell and Skylake.
I don't think it ever affected production hardware, so at this point it
probably makes sense to delete it.

Commit 4bdbb588a9 introduced new _glapi_new_nop_table() and
_glapi_set_nop_handler() functions in the glapi dispatcher (which
live in libGL.so). The calls to those functions from context.c
would be undefined (i.e. an ABI break) if the libGL used at runtime
was older.
For the time being, use the old single generic_nop() function for
non-Windows builds to avoid this problem. At some point in the future
it should be safe to remove this work-around. See comments for more
details.
v2: Incorporate feedback from Emil. Use _WIN32 instead of
GLX_DIRECT_RENDERING to control behavior, move comments.

argparse type is a nice type saver for simple data types, but it doesn't
look a good fit for the input XML file:
- Certain implementations of argparse (particularly python 2.7.3's)
invoke the type constructor for the default argument even when an
option is passed in the command line. Causing `No such file or
directory: 'gl_API.xml'` when the current dir is not
src/mapi/glapi/gen.
- The parser takes multiple arguments. This is currently worked around
using lambdas, but that unnecessarily complex and hard to read.
Furthermore it's odd to have a side-effect as heavy as parsing XML
happening deep inside the argument parsing.

Without it, texcoords are mapped to GENERIC[0..7], PointCoord is mapped to
GENERIC[8], and user-defined varyings start from GENERIC[9]. Since texcoords
can only be used between VS and PS, and PointCoord is PS-only, it's silly to
always start from GENERIC[9] in all other shaders (such as LS, HS, ES, GS).
This adds support for TEXCOORD and PCOORD semantics. As a result, st/mesa
will use GENERIC[0] as a base for user-defined varyings, which should make
linking ES and GS as well as tessellation shaders at runtime easier.

When using SIMD4x2 on Skylake, the sampler instructions need a message
header to select the correct mode. This was added for most sample
instructions in 0ac4c2727 but the TXF_MCS instruction is emitted
separately and it was missed.
This fixes a bunch of Piglit tests which test texelFetch in a geometry
shader, for example:

The problem is that the EDGEFLAG has to be toggled at vertex submission
time. This can be done from either the draw or the regular paths. Avoid
falling back to draw just because there's an edgeflag.

Commit 8acaf862df switched things over to use TEXCOORD instead of
GENERIC, but did not update the nv30 swtnl draw paths. This teaches the
draw logic about TEXCOORD.
Among other things, this fixes a crash in demos/arbocclude when using
swtnl. Curiously enough, the point-sprite piglit works without this.

Clearing can happen at a time when various state objects are incoherent
and not ready for a draw. Some of the validation functions don't handle
this well, so only flush the framebuffer state. This has the advantage
of also not doing extra work.

There can be scenarios where the "indirect" arg of a PFETCH becomes
