Making sure that we correctly collect the exit codes from all children
is a bit a hassle. So add another magic igt codeblock for easy forking
and joining.
Note that children are (currently at least) not allowed to call igt_skip.
Add an assert to enforce this.
v2:
- Properly propagate the exit code.
- Fix the segfault.
- Add a child int and num_children paramter to the magic codeblock as
suggested by Chris Wilson.
- Don't dump noise into stdout when a child thread fails, the parent
will do that for us already.
v3: Now with some docs.
v4: Fixup igt_waitchildren to properly reset state so it can be used
again.

For machine with split BCS/RCS rings, we also need to test whether we
correctly wait upon outstanding render work before flipping and changing
modes. This should also serve to exercise the ring selection code for
flips.

Longjmp creates havoc with stack variables of the current stackframe.
And since fixtures should be used to set up such variables creating
havoc isn't a great idea. With this I can revert a bunch of
bogus patches I've done to paper over this by moving stack variables
to be global.
The same issue is actually a feature for subtest blocks since subtests
should be independant anyway.

At the moment any command line option handling done by tests will
interfere with the option handling of the subtest interface. To fix this
add a new version of the subtest_init function accepting optional short
and long command line options. Merge these together with the subtest
interface's own long options and handle both together in the same
getopt_long call.

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.

This way we can just enclose all igt_skip/igt_require calls into
fixtures even when we have subtests, and still output correct SKIP
message for all of them. Wohoo, magic!
The only thing which doesn't work yet is enumerating failed subtests,
but I think that should work out on top of this.

abort results in "crash" test results in the piglit runner, igt gives
us neater output.
The downside is that we can now only use these in igt tests, but
that's already the case (and given their placement in drmtest.h their
intended use-case, too).

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.

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.

The aim is that we keep on running subtests even when a not-too-lethal
assert failed in a subtest. To make that useful also print per-subtest
test results from igt_skip|fail|success functions.
If required we can always go googletest-nuts with different types of
asserts later on, but I think for now we're good with what we have
here.
v2: Also print out proper SKIP message when skipping all subsequent
tests since a global (i.e. outside of a subtest) init step failed and
resulted in an igt_skip call.

Now that callers must setup the longjmp target (we can't do that in

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.

Exitcode handling in igt testcases has too ugly facets in combination
with subtests:
- When individual subtest needed to be skipped for different reasons
we need to painstakingly thread this information through the test to
make sure that we still succeed if just one testcase worked (for
running it with the simple automake test runner in igt). But it also
needs to correctly report the skip exit value if only this one
skipped testcase has been run (e.g. when run with piglit or in QA's
test infrastructure).
- We'd prefer to easily skip (and also fail) subtests without
hampering other subtests. Again threading the return value of each
subtest through the code is cumbersome.
To simplify test case writing use longjmps to be able to get out of
subcases easily. But since longjmps are funny things thug it all away
into the newly added drmtest_subtest_block macro.
Note that if drmtest_skip is called outside of a subtest, but in a
testcase with subtests all subsequent subtests will be automatically
skipped.

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.
