i965: Upload invariant state once at the start of the batch on Gen4-5.

We want to emit invariant state at the start of a render batch.  In the
past, this more or less happened: a new batch flagged BRW_NEW_CONTEXT
(because we don't have hardware contexts), which triggered the
brw_invariant_state atom.  So, it would be emitted before any 3D
drawing.  (Technically, there might be some BLT commands in the batch
because Gen4-5 have a single combined render/BLT ring, but that should
be harmless).

With the advent of BLORP, this broke.  The first item in a batch might
be a BLORP operation, which bypasses the normal draw upload path.  So,
we need to ensure invariant state happens first.  To do that, we just
upload it when creating a new batch.  On Gen6+ we'd need to worry about
whether it's a RENDER or BLT batch, but because we have a combined ring,
this approach should work fine on Gen4-5.

Seems to fix GPU hangs when playing hardware accelerated video with
mpv -hwdec=vaapi on Ironlake.

mesa: call _mesa_make_extension_string only as needed

As of previous commit we removed the extension overrides from this
function.

Thus we no longer need to call it during MakeCurrent, so we can
construct the extensions string when needed - _mesa_GetString.

This commit effectively reverts a879d14ecf8 ("mesa: initialize extension
string when context is first bound")

mesa: split extensions overrides and glGetString(GL_EXTENSIONS)

Currently we apply the extension overrides and construct the extensions
string upon MakeCurrent.

They are two distinct things, so let's slit the two while pushing the
overrides management _before_ _mesa_compute_version(). This ensures that
the version is updated to reflect the enabled/disabled extensions.

meson: Don't define HAVE_PTHREAD only on linux

I'm not sure of the reason for this. I don't see anything like this in
configure.ac

In include/c11/threads.h the cases are:

1) building for Windows -> threads_win32.h
2) HAVE_PTHREAD -> threads_posix.h
3) Not supported on this platform

So not defining HAVE_PTHREAD for anything not Windows just means we can't
build at all.

When we are building for Windows, I'm not sure if dependency('threads')
would ever find anything, or defining HAVE_PTHREAD has any effect, but avoid
defining it there, just in case.

etnaviv: Add sampler TS support

Sampler TS is an hardware optimization that can be used when rendering
to textures. After rendering to a resource with TS enabled, the
texture unit can use this to bypass lookups to empty tiles. This also
means a resolve-in-place can be avoided to flush the TS.

This commit is also an optimization when not using sampler TS, as
resolve-in-place will now be skipped if a resource has no (valid) TS.
