Add a header that includes all the headers for the library. This allows
reorganisation of the library without affecting programs using it and
also simplifies the headers that need to be included to use the library.

The integer comparison macros give us better error output by including
the actual values that failed the comparison.

Increate the GPU load slightly, but mitigate the CPU overhead from
clflushing by keeping the object alive using flink. This has also the
side-effect of magnifying the desired busy-close race.

The challenge here is to race GPU activity versus the gem_close. Using a
large objects makes the window of GPU activity larger - except on !llc
systems we then incur massive overhead from clflush, likely destroying
any race (due to mutex contention). And that mutex contention is
amplified by the number of cores - bad news for Baytrail.
Give up and make the objects smaller and hope that the test is run
frequently enough to catch the race.

Brought a few missing headers to light in ioctl_wrappers.h, too.

Blows up otherwise if there's no intel gpu around.

With Full PPGTT, each new fd creates a new context and thus a new
PPGTT, so we have to reduce the number of simultaneous fds or face
OOM problems. For every new PPGTT, its PDEs are stored in the GGTT
which imposes a limit of 1024 new contexts. We want to leave at
least 1/4 of the GGTT available for "important" stuff like scanout
buffers, so never open more than 768 fds.
v2: Unconditionally use the lower limit, as suggested by Daniel
Vetter

In the past new testcases with subtest often forgot to add the call to
igt_exit at the end of their main() function. That is now caught with
a bit more obnoxious asserts, but it's still a nuissance.
This little igt_main macro takes care of that (and also of calling the
subtest machinery initialization code correctly).
If no one objects I'll roll this out for all the simple cases (i.e.
those tests that don't have additional argv parsing on top of the
subtest machinery).
v2: Roll it out across the board.

Emit more work per client and many more clients in order to increase the
chance of racing i915_gem_release() and i915_gem_retire_requests()

Pass the right pointer to the execlist would be a good start.

The intention is to exercise #70784. Yet the first challenge is make the
test suite happy.
