libdrm_radeon: Optimize cs_gem_reloc to do less looping.
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%.
