Yay for breaking piles of tests.

In order to exercise https://bugs.freedesktop.org/show_bug.cgi?id=84207
we need to interrupt the mmu_notifier_register with a signal. This is
likely to be quite difficult, but let's just try running the
create-destroy test in an interruptible loop for 5s.

Two parts to the fix:
1. Do not use pthread_cancel since not available on Android.
2. Do not assert in the thread since that does not get propagated
to the process. Rather pass out any failures so we know test
did not work as expected.

Introduce a new test to keep that we clean up on process exit (if the
userptr is busy or it has been gtt mmapped). This revealed a few bugs in
the existing tests so clean those up.

- Drop return values for test functions - we rely on the implicit
control flow from igt_ checks.
- Don't use assert directly, this upsets the test flow logic (and
results in a CRASH result instead of FAIL).

Userptr v23 was not thread safe against memory map operations and object
creation from separate threads. MMU notifier callback would get triggered
on a partially constructed object causing a NULL pointer dereference.
This test excercises that path a bit. In my testing it would trigger it
every time and easily, but unfortunately a test pass here does not guarantee
the absence of the race.
v2: Added explicit cancellation point and removed the stop flag.
Use only igt_assert().

If the parent passes a userptr to some private memory, we expect to
still be able to use the userptr in the child.

The forked tests allocate the bo (and thus for userptr, the memory) in
the parent and pass them to all children. The difference for userptr is
that we allocate system memory which the kernel then copies into each
child. As the children need to access the memory for their checks, it
does need to be shared - so allocate the userptr from shared memory!

If we move the assertion from out of the callback, we can get a much
more useful error message.

When the patch was merged, the ioctl numbers had to be adjusted to leave
no holes. Also there was a final piece of munging of the API to
downgrade unsynced userptr for export over dma-buf.

Often just folding together of the common if (cond) printf;
abort|igt_skip|igt_fail; pattern. But in a few cases I've ripped out
more since the igt macros will already print the condition and errno.
A few tests where more work (like ripping out return codes en masse)
is needed left as-is.

All the cases that simply dump some debug information and couldn't be
converted to some of the fancier macros.
Some information output removed when it's redundant with the subtest
status.

Also shut up warnings. Those revealed incorrect usage of local
variables in conjunction with igt_fixture/igt_subtest. Since those use
longjmps we need to move the out of the stackframe those magic blocks
are declared in.

A set of userptr test cases to support the new feature.
For the eviction and swapping stress testing I have extracted
some common behaviour from gem_evict_everything and made both
test cases use it to avoid duplicating the code.
Both unsynchronized and synchronized userptr objects are
tested but the latter set of tests will be skipped if kernel
is compiled without MMU_NOTIFIERS.
Also, with 32-bit userspace swapping tests are skipped if
the system has a lot more RAM than process address space.
Forking swapping tests are not skipped since they can still
trigger swapping by cumulative effect.
v2:
* Fixed dmabuf test.
* Added test for rejecting read-only.
* Fixed ioctl detection for latest kernel patch.
v3:
* Use ALIGN macro.
* Catchup with big lib/ reorganization.
* Fixed up some warnings.
