For seqno comparison to work they have to be less than UINT32_MAX/2
apart. So when crossing the half way of seqno space, be careful not
to sync anything as this causes gpu hangs. Do real test with
syncing only when we are about to wrap.
v2: Don't spam if no rendercopy was found, only warn once
Needed by clock_gettime(). This isn't a problem if libudev is used,
as that pulles librt with it.

drm/i915: Remove check for conflicting relocation write-domains
Everywhere else we search for a match based on an Intel display
device, so if the quick check of the fixed slot fails, fallback to
walking the PCI bus looking for a match.

This test uses debugfs entry to set next_seqno close
to a wrapping point and then creates a load with dependant
buffer objects or with specified command to induce the wrap.
v2: Use new get_rendercpy_func as suggested by Daniel Vetter.

flink names may not be destroyed while there's still a userspace
handle around. Test this by
- exporting an flink name from fd2
- open a gem bo from that name in fd
- close fd2, then open a new drm file (so that the original handle
disappears)
- check whether the same flink name still works
- mulitple write domains
- conflicting write domains
- not-yet-defined gpu domains
Also convert to subtests while at it.

Again required a bit of shuffling to avoid expensive setup and some
logic to properly handling 'skip' when only running a subtest.

Small changes to avoid expensive setup just to print out the subtest
list, and setting up the source buffers such that "early-read" works
without having run "overwrite-soure" right beforehand.

To make the testnames easier to handle in scripts, replace all
spaces with dashes.
The important part is to not print anything to stdout when enumerating
subtests, so protect the timestamp test with the right check.

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.

Results in spurious 'warn' results in piglit. Also don't print

This is getting in the way of piglit integration. If we want this
functionality again, we should integrate it into the IGT piglit runner
as an option.

Piglit needs a way to grab the latest list of tests to run, so add new
make targets to dump those. Note that for future extendability we'll
dump 2 different lists, one for single-testcase tests and one for
testcases with enumerable subcases. Some support code for the later
will follow in subsequent patches.

Since monotonic timestamps are now the preferred time format, change
timestamps checks to compare against monotonic instead of real time.
Also add two tests for DRM's compatibility mode where it returns real
timestamps.
v2: drop the tests for the compatibilty mode (Daniel)

The old way worked too, but just skipping the test for the first event
is more logical/simpler thing to do.

In v2:
- Wait for the seq that just completed (current_seq) not last_seq - 1.
- Do an equality check for ts and seq instead of >=. The previous
issue didn't let us do this before.
- Simplify the condition when we do an "expired sequence" check by
only using the last flip event as a reference.
