flip_test: add event sequence number tracking

... to test the latency of rmfb, getfb and addfb. Since if those still
can cause spikes, we have a problem.

This way we can still test basic pageflips on kernels with broken
locking while still failing when the timestamps/framecounts are wrong.
Also disable the delay check on analog tv, timings on those ports are
truely screwed-up

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.
