The motivation behind this is that by shipping it here, it's essentially
an API which causes issues while bisecting across changes to the header
files.
Dump command stream + associated bo into a binary file
which follow a similar design as json file. It allows
to intercept a command stream and replay it in a standalone
program (see radeondb tools).
Fixes problem that libdrm_radeon was disabled in Makefile even when configure
claimed that radeon was enabled.

intel_bufmgr.h is installed in ${includedir} directly, and the other
headers are taken care of by libdrm.pc's Cflags.

This is the largest untiled pitch requirement from gen2 through gen4.
It's only the case for gen3 rendering to color regions with depth, but
it's rare for this to be a significant factor in memory usage -- for
example, gen4 requires 1 or 2 times the element size, or up to 64
bytes depending on the size of the elements. This is easier than
encoding all the various little quirks for untiled pitch alignment,
since we rarely do untiled now.
bo->referenced_in_cs is checked if bo is already in cs. Adding and removing
reference in bo is done with atomic operations to allow parallel access to a
bo from multiple contexts.
cs->id generation code quarentees there is not duplicated ids which limits
number of cs->ids to 32. If there is more cs objects rest will get id 0.
V2:
- Fix configure to check for atomics operations if libdrm_radeon is only selected.
- Make atomic operations private to libdrm.
This optimization decreases cs_write_reloc share of torcs profiling from 4.3%
to 2.6%.

intel_atomic.h includes very usefull atomic operations for
lock free parrallel access of variables. Moving these to
core libdrm for code sharing with radeon.

This allows Mesa to use drm_intel_bo_alloc_tiled() for its tiled
buffers, since it makes its decision about pitch before telling
libdrm. They happen to be the same choices for the tiled case.
- Currently reloc'ing a user bo to gart will first cause an allocation in vram,
which is then written to by cpu, then the bo gets moved to gart.

This patch to libdrm adds support for the new execbuf2 ioctl. If
detected, it will be used instead of the old ioctl. By using the new
drm_intel_bufmgr_gem_enable_fenced_relocs(), you can indicate that any
time a fence register is actually required for a relocation target you
will call drm_intel_bo_emit_reloc_fence instead of
drm_intel_bo_emit_reloc, which will reduce fence register pressure.
