mesa: Fix ReadBuffers with pbuffers

pbuffers are internally single-buffered.  Marek fixed DrawBuffers to
handle this case, but we need to fix ReadBuffers too.  Otherwise,
pretty much every conformance test fails because glReadPixels breaks.

intel/fs: Stop stack allocating large arrays

Normally, we haven't worried too much about stack sizes as Linux tends
to be fairly friendly towards large stacks.  However, when running DXVK
apps under wine, we're suddenly subject to Windows' more stringent stack
limitations and can run out of space more easily.  In particular, some
of the shaders in Elite Dangerous: Horizons have quite a few registers
and the arrays in split_virtual_grfs are large enough to blow a 1 MiB
stack leading to crashes during shader compilation.

virgl: fix a sync issue in virgl_buffer_transfer_extend

In virgl_buffer_transfer_extend, when no flush is needed, it tries
to extend a previously queued transfer instead if it can find one.
Comparing to virgl_resource_transfer_prepare, it fails to check if
the resource is busy.

The existence of a previously queued transfer normally implies that
the resource is not busy, maybe except for when the transfer is
PIPE_TRANSFER_UNSYNCHRONIZED.  Rather than burdening us with a
lengthy comment, and potential concerns over breaking it as the
transfer code evolves, this commit makes the valid_buffer_range
check the only condition to take the fast path.

In real world, we hit the fast path almost only because of the
valid_buffer_range check.  In micro benchmarks, the condition should
always be true, otherwise the benchmarks are not very representative

mesa: add EXT_dsa glEnabledIndexedEXT

The implementation uses _mesa_ActiveTexture to change the active texture unit and
then reset it.

It causes an unnecessary _NEW_TEXTURE_STATE but:
  - adding an index argument to _mesa_set_enable causes a lot of changes (~140 callers)
  - enable_texture (called by _mesa_set_enable) might cause a _NEW_TEXTURE_STATE
    anyway.

egl: drop incorrect pkg-config file for glvnd

With b01524fff05eef66e8cd ("meson: don't build libGLES*.so with GLVND")
we dropped the incorrect pkg-config files for GLES*.

Since then, the glvnd issue of its missing files has become painfully
apparent, since it break the build for everyone using glvnd.

NVIDIA has had a fix for a few years now, but has yet to accept it:
https://github.com/NVIDIA/libglvnd/pull/86

Since the breakage is already there, let's clean up everything on our side
while we wait for NVIDIA to accept the fix.
