Our kernel likes to occasionally kill process with a SIGBUS when this
shouldn't ever happen. Hence also handle this signal in the exit
handler infrastructure.

Instead of crashing with an igt_assert. Fixes the only crashing test
when running igt on non-intel systems.

The upshot is that we can share the logic to make sure the helpers
are all properly stoved again in a 2nd step.

- reset the count when forking
- don't add the same handler multiple times
- don't restore the exit signal handlers in the forked helper
process
- reset the exit handler count once called to make sure we don't call
it multiple times when dying
- don't wait for the signal helper if it's gone already

intel_batchbuffer: add support for non-32bit blt copies
No functional change.

I've fumbled the logic inversion when converting to igt_require way
too often, so lets add something for dummies like me ;-)

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.

So far we handled -h or --help arguments properly only if the test
called igt_subtest_init_parse_opts(). Fix this for igt_subtest_init()
callers too. Make sure we still don't exit for any other
unknown options, which the caller may parse with a second getopt scan.

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).

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.

With the abortable fixtures we can now correctly fail all subsequent
sutbests if we hit upon an igt_assert outside of a subtest.

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.
