lib/drmtest: skip fixtures after an igt_skip
pushed the stack space requirement for run_modes over some magic limit
(I guess where the strack grow logic starts to fail, but I didn't
check). Fix this by moving the data into .bss.
Also add some asserts to check that fixtures aren't abused while at
it (i.e. the useful parts of my debug printf/assert craze).

Iterate through all valid/invalid crtc/connector combinations. At the
moment only clone configurations are tested as the single output cases
are tested already by testdisplay. Also from combinations where all
connectors are on the same crtc (clone-single-crtc) only those are
tested that are invalid, as I haven't found any machine that supports
these (have to be GT2 with dvo and vga output).
For configurations with one crtc per connector the FBs are per-crtc atm.

It's unused. Also most of our tests failed to ask for the right type
of drm fd anyway. So it's imo better to just let them fall over when
they don't get master but want it, like they already do today.
This also allows us to garbage-collect the master parameter to
drm_get_card and associated code.

As the children use the parent's fd, the kernel only has a single filp
for everyone. Therefore we cannot rely on the process termination
reaping the buffers we allocate for the children.

... instead of threading the 77 return value through threads. Even
better would be to check for requirements in the single-threaded setup
part of the test, since now it's done by multiple threads in parallel
and will result in interleaved and multiplied output on stdout.
Whatever.

... and drop the int return argument of the tests.
Also:
- make nv_write_i915_cpu_mmap_read functional again by dropping the
goto.
- add checks to i915_import_pread_pwrite

Also sprinkle igt_assert and igt_require over the setup code to clean
up code while at it. To avoid gcc getting upset about unitialized
variables just move them out of main as global data (where they always
get initialized to 0) - gcc can't see through our igt_fixture and
igt_subtest maze properly.

Just a tiny wrapper to protect global test setup/teardown code when
just listing subtests. Rolling this out over all tests with subtests
should allow us to generate the testlist with piglit as an
unpriviledged user on a non-intel system.
The aim here is to make our QA team happy who currently suffers from
this. Even more so for the prime tests since you need a system with
intel _and_ nouveau gpus to just be able to list tests.
Exemplary conversion with gem_concurrent_blt.c
Fixture is the same name other test suites like googletest use for
setup/teardown code used by multiple tests.

This is mostly important to get the SKIP reporting right, but I've
found a few stragglers that wanted to get converted over to the igt
result reporting completely.

Useful when stitching together combinatorial testnames.
v2:
- ## rules are just fun. We need 2 indirections to actually get
__LINE__ to properly expand.
- Kill stray ; which botched the logic.

For tests with subtest we should use igt_skip to ensure that subtests
are always properly enumerated.

An oversight in the mass conversion to the new framework as the test was
called from two locations.
Ideally, the checks could be moved back to the caller and the framework
still work. This is just the patch of least resistence.

Simultaneously make the results more robust and compact by performing a
linear regression to compute the amount of time required to perform the
exec array walk and the relocations.
Since igt_skip has funny control flow we can abuse it and make it work
like a special kind of assert which automatically skips tests if a
requirement fails.
Note that in places where we have a less strict test which should
always succeed (e.g. ioctl works or isn't available) the igt_assert
should be place before the igt_require with the more strict
requirements. Otherwise we'll skip a test instead of properly failing
it.
Convert a few users of igt_skip over to igt_require to showcase its
use.
v2: s/gem_check_/gem_require_/ so that we consistently use "require"
to indicate magic check that can call igt_skip. Imo hiding the
igt_require for feature checks is ok, but for more traditional assert
like use cases an explicit igt_require might be better.

Mostly a sed job with too manual fixups:
- one case of using _exit instead of exit
- and one case which under some conditions use 77, so convert that
check to an igt_skip.

A bit lazy since the read/write tests are all smashed together. But
since we have really evil partial write/read tests for coherency
checking that doesn't matter that much really.

Upstream broke our dynamic creation of the testlist, and I think
adding stupid .tests suffixes everywhere just to appease upstream
autohell tools isn't that great. So scrap it, we can use piglit
instead.

The _block postfix meant to convey that a C statement/block must
follow can be misread as the verb to block. So drop it.

To simplify things add a set of gem_check_<ring> functions which take
care of this. Since I've opted for static inlines drmtest.h grew a few
more header includes which was a neat opportunity to dump a few redundant
#defines.
This kills all the skipped_all hand-rolled logic we have.

This way we can rip out all the skip handling from the test control flow,
and additionally (by using drmtest_retval()) even get correct exit codes.
The only tricky part is that when we only want ot skip parts of a test
(like for gem_pread and gem_pwrite) we need to split out those parts as
subtests. But no addition of control-flow is required, the set/longjmp
magic in the helpers all makes it happen.
Also we make extensive use of the behaviour of drmtest_skip to skip
all subsequent subtests if it is called outside of a subtest. This allows
us to re-flatten the control flow a lot.

Doesn't do more than an if (drmtest_run_test(name)) right now, but
as soon as we get a bit of infrastructure to handle test failures and
skipping, this will get more interesting.
