prevent re-definitions from drm.h

merge Mesa 18.3.4.

this work is mostly from maya@ with a little help from myself
via these github commits:


commit 57df9d9b59df14fd6ac8e30832ce4f29572a33c0
Author: coypu <coypu@sdf.org>
Date: Mon Mar 4 12:24:37 2019 +0200

Make GCC happier about prototype, include right header for __HAVE_ATOMIC64_OPS

commit 93c2f416aa316cc3d0665661c9f927f6949cdd37
Author: coypu <coypu@sdf.org>
Date: Mon Mar 4 12:16:56 2019 +0200

Make the u_atomic.c fallback locked 64bit atomics more suited

for the netbsd case: we are using __GNUC__ compilers, but without
libatomic. so we are emitting the __GNUC__ names.

Use __HAVE_ATOMIC64_OPS which is the netbsd name for this condition
(we don't run configure)

Date: Sun Mar 3 20:02:38 2019 +0200

Remove unused padding to struct.

The extra space is in the flexible array member at the end of
struct drm_i915_query_topology_info.

Clang dislikes having an extra member to the struct after the flexible
array member.

Author: Maya Rashish <maya@NetBSD.org>
Date: Wed Feb 6 13:07:55 2019 +0200

Apply patches from pkgsrc mesa to avoid atexit on a library.

This isn't safe to do on netbsd and results in segfaults on
program exit.

radeon picture_type is h264 and the enums match, cast to avoid

clang warning (we use -Werror)
