This patch adds a context creation ioctl wrapper that returns the error
for the caller to consume. Multiple tests that implemented this already,
have been changed to use the new library function.
v2:
- Add gem_require_contexts() to check for contexts support (Chris)
v3:
- Add gem_has_contexts to check for contexts support and change
gem_require_contexts to skip if contests support is not available.
(Chris)
v4:
- Cosmetic changes and use lib function in gem_ctx_create where
possible. (Michal)
v5:
- Use gem_contexts_require() in tests and fixtures. (Chris)

Avoid the globals and make the dispatch one huge function and hope GCC
works some magic.

Just on the off chance someone is replaying a bunch of traces, remember
to cleanup up.

Use madvise(MADV_SEQUENTIAL) to let the kernel optimise for our
straightforward sequential read pattern.

When reallocing the bo array, remember to set the new entries to 0.

This slightly idealises the behaviour of clients with the aim of
measuring the kernel overhead of different workloads. This test focuses
on the cost of relocating batchbuffers.
A trace file is generated with an LD_PRELOAD intercept around
execbuffer, which we can then replay at our leisure. The replay replaces
the real buffers with a set of empty ones so the only thing that the
kernel has to do is parse the relocations. but without a real workload
we lose the impact of having to rewrite active buffers.
