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.

If we skip a test and and fail somewhere the parent might die before the
child. So add some cleanup to handle this case. Also make sure that the
parent indeed waits for the child to die.
This is required to make the latest version of the piglit runner happy,
it tends to wait for all zombies to disappear.

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.

In the atexit handler, we attempt to quiesce the GPU. This involves
opening a fd - which will fail if the test is not being run as root and
will obliterate the test status and pollute the output.
Add a test going through all connectors/crtcs/modes/formats painting to
a front FB with CPU or painting to a back FB with CPU and blitting it
to the front FB.
Only formats understood by cairo are supported for now.

In some environments, we don't really want to loop 100000 times or
allocate 152352621 buffers because it makes the tests too long to run.
This adds a way to specify "quick" values to reduce the time taken by
certain tests.

To make these helpers as least invasive as possible simply initialize
the options with a getopt parser and let the control flow be steered
with a simple helper which gets the subtest name as an argument.
The only tricky part for using it is that the subtest check helper
doubles up as the conduit to enumerate tests (and in that mode
prevents any test from being run). It is therefore important that
nothing gets printed to stdout outside of these checks.

With the option '-r', the testdisplay could paint a 2-D bar code(QR
bar code) on the screen. The word "pass" is hiden in the bar code
image. Further more, with this option, testdisplay will wait until a
system signal 'SIGUSR1' coming after each mode setting. This function
is for another program to control testdisplay.
