Currently we have multiple different parts of IGT that define their own
wrapper around the gettid() syscall (or just call it directly with no
wrapper).
Additionally, add the appropriate #includes for igt_aux.h to make sure
syscall() is available.

We're creating our own namespace and then create a copy of the chardev
that anyone can access before dropping root. Should hopefully work on
any system.
This way we're also guaranteed to open the right device again.
v2: mount(2) instead of mount(3).
v3: Drop execute bits from our temporary chardev (Chris).

As the inline comment says, this test checks that the kernel allows
unauthenticated master with render capable, RENDER_ALLOW ioctls.
The kernel commit has extra details why.
v2:
- drop RUN_AS_ROOT guard
- call check_auth() on the {,un}authenticated device
- check the device is PRIME (import) capable
- check the device has render node
- tweak expectations based on above three
- elaborate why we care only about -EACCES
v3:
- fold into existing core_auth.c
- move igt_assert within the subtest
- make has_prime_import() an igt_require()
- check for BADF before and after, as requested. Not strictly needed.
- swap igt_info+drm_open_driver with comment + __drm_open_driver
Former calls igt_skip() which is problematic with igt_fork().

Emil has another auth test which could use the check_auth function, so
best to merge them all.
We need a subtest group and put the tests which need to fully control
who's master and how many open drm fd there are first.

Some distros have huge rlimits and then the test takes forever, or
worse oom, or even worse, takse down the entire machine (which is
shouldn't be able to, but oh well, oom handling in linux).
Make sure we have a consistent rlimit by adjusting it manually.
v2: Use the default of 1024 from everywhere except ubuntu.

It really is a core drm testcase and not a libdrm testcase. While at it
also make it generic, since it is.
