1d6b71c5c6 glapi: Mark vertex attrib pointer functions as async.
These don't actually read data out of the pointers, they set the
pointers (or offsets in a VBO) to be used in a later draw call.

v2: Don't forget glVertexAttribIPointer, and don't bother with annotations
    on aliases.
v3: Mark CompressedTexSubImage1D as sync also.

ef30ce97a6 mesa: Create pointers for multithread marshalling dispatch table.
This patch splits the context's CurrentDispatch pointer into two
pointers, CurrentClientDispatch, and CurrentServerDispatch, so that
when doing multithread marshalling, we can distinguish between the
dispatch table that's being used by the client (to serialize GL calls
into the marshal buffer) and the dispatch table that's being used by
the server (to execute the GL calls).

f05524ffaa glapi: Mark compressed teximage functions as sync.
Without doing some additional tracking, we won't know whether the data
will be immediate user data, or will be loaded from a PBO.  The normal
teximage functions will be sync by default because they don't know up
front what the size of their image data is.  But for compressed teximage,
we have the count information, so they would end up async by default.

f5052f45a2 glapi: Annotate functions with "marshal" attribute.
Several API functions require special treatment in order to be marshalled
to a background thread.  Others can't be safely executed in a background
thread and need to be executed synchronously (e.g. since they return data
through a pointer argument).

This annotation will be used when code generating thread marshalling code,
to ensure that each function is marshalled in the correct way.

Note that PixelMap functions are marked as synchronous for now since
their pointer may be relative to buffer on the GPU, so we'll need
special logic to marshal them properly.

v2: Move description of attribute types to a comment in the dtd file.

d83a33a9de mesa: Separate INTEL_performance_query frontend
To allow the backend interfaces for AMD_performance_monitor and
INTEL_performance_query to evolve independently based on the more
specific requirements of each extension this starts by separating
the frontends of these extensions.

Even though there wasn't much tying these frontends together, this
separation intentionally copies what few helpers/utilities that were
shared between the two extensions, avoiding any re-factoring specific to
INTEL_performance_query so that the evolution will be easier to follow
later.

15a084a039 glapi: Move PrimitiveBoundingBox and BlendBarrier definitions into ES3.2 category.
These two GLES 3.2 entry points were being defined in the category of
the ARB_ES3_2_compatibility and KHR_blend_equation_advanced extensions
respectively instead of in the ES3.2 category.  Defining them in the
ES3.2 category makes sure that the gl_procs.py generator emits
declarations in the glprocs.h header file for the unsuffixed GLES-only
entry points that PrimitiveBoundingBoxARB and BlendBarrierKHR
respectively alias.  This should avoid a compilation failure during
scons builds in combination with "mapi: export all GLES 3.2 functions
in libGLESv2.so".

Which breaks the scons build in an interesting way, particularly when
BlendBarrier and PrimitiveBoundingBox are added to static_data.py's

533b3530c1 direct-to-native-GL for GLX clients on Cygwin ("Windows-DRI")
Structurally, this is very similar to the existing Apple-DRI code, except I
have chosen to implement this using the __GLXDRIdisplay, etc. vtables (as
suggested originally in [1]), rather than a maze of ifdefs.  This also means
that LIBGL_ALWAYS_SOFTWARE and LIBGL_ALWAYS_INDIRECT work as expected.

[1] https://lists.freedesktop.org/archives/mesa-dev/2010-May/000756.html

This adds:

* the Windows-DRI extension protocol headers and the windowsdriproto.pc
file, for use in building the Windows-DRI extension for the X server

* a Windows-DRI extension helper client library

* a Windows-specific DRI implementation for GLX clients

The server is queried for Windows-DRI extension support on the screen before
using it (to detect the case where WGL is disabled or can't be activated).

The server is queried for fbconfigID to pixelformatindex mapping, which is
used to augment glx_config.

The server is queried for a native handle for the drawable (which is of a
different type for windows, pixmaps and pbuffers), which is used to augment
__GLXDRIdrawable.

Various GLX extensions are enabled depending on if the equivalent WGL
extension is available.

a1c5cd426c glapi/glx: Add overflow checks to the client-side indirect code
Coverity complains that the computed sizes can lead to negative lengths
passed to memcpy. If that happens we've been handed invalid arguments
anyway, so just bomb out.

The funky "0%s" is because the size string for the variable-length part
of the request is of the form "+ safe_pad() ...", and a unary + would
coerce the result to always be positive, defeating the overflow check.

1c1873b93b mesa: Implement glGet*(GL_PRIMITIVE_RESTART_FOR_PATCHES_SUPPORTED).
Technically, this was introduced with GL 4.4.  However, I believe it
was intended to be retroactive.  As far as I know, AMD has never
supported primitive restart with patches, while NVidia and Intel do.
This necessitated the need for a query which would allow applications
to figure out whether this was usable or not.

I decided to expose it everywhere ARB_tessellation_shader is exposed.
(It's also in both OES and EXT_tessellation_shader.)

Enable this for i965 and Gallium drivers which expose the capability.
