(cherry picked from commit d6724471)

Depending on whether compiled with frame-pointer or not, the temporary
memory location used for the bp parameter in these macros are referenced
relative to the stack pointer or the frame pointer.
Hence we can never reference that parameter when we've modified either
the stack pointer or the frame pointer, because then the compiler would
generate an incorrect stack reference.

Fix this by pushing the temporary memory parameter on a known location on
the stack before modifying the stack- and frame pointers.

Also in case of failuire RPCI channel is not closed which lead to vmx
running out of channels.

With the newer (v1.76) fw, we were getting hangs (compared to older
v1.66 fw).  Re-work the GMEM code to structure things a bit closer to
the blob.  This moves some PKT7 packets from IB2 to IB1, which I think
is what was confusing SQE and causing it to get stuck in an infinite
loop.  But in general structuring things at least closer to the same way
blob does makes it easier to compare cmdstream.

Note: this is a bit on the large side for what I'd normally consider for
stable.. but right now it is looking  like it is the newer fw that is
headed for linux-firmware.  This should defn have some soak time on
master, but probably a good idea for this patch to end up in distro mesa
builds by the time a630_sqe.fw hits linux-firmware.

Commit 2282ec0a refactored drawable creation across various platforms
into a new dri2_create_drawable helper function.

The GBM code in platform_drm.c code passed in dri2_surf->gbm_surf as the
loaderPrivate, while most other backends passed in dri2_surf directly.

To try and handle this, the patch checked if dri2_surf->gbm_surf was
non-NULL, and if so, presumed that the caller is the DRM platform and
we should use the dri2_surf->gbm_surf pointer.

This worked for most platforms, which calloc their dri2_surf structure,
zeroing the data.  Unfortunately, platform_x11.c used malloc, leaving
most of the dri2_surf as garbage.  In particular, dri2_surf->gbm_surf
was often non-NULL, causing dri2_create_drawable to try and use it,
passing a garbage pointer to the createNewDrawable hook, usually leading
to a SIGBUS or SIGSEGV when trying to dereference that bad pointer.

Since most callers calloc the data, make platform_x11.c follow suit.

Earlier commit converted ES1 and ES2 to a new, much simpler, dispatch

using the old code.

There is a hidden ABI between GL*.so and glapi.so, former referencing
entry-points by offset in the _glapi_table. Hence earlier commit added
the full table of entry-points, alongside a marker for other cases like
indirect GL(X) and driver-size remapping.

Yet the patches did not handle things fully, thus it was possible to
get different interpretations of the dispatch table after the marker.

This commit fixes that adding an indicative error message to catch
future bugs.
