In commit 3f6ae7b19 ("igt/kms_frontbuffer_tracking: Keep the debugfs
dir around") we introduced custom variant of __igt_debugfs_read function
that fires assert when debugfs returns an error. Replace that assert
with proper error handling to allow use of errors like -ENODEV.
v2: allow only -ENODEV (Chris)

Compiler complained on crc_lowres and crc_hires2 being uninitialized
and indeed, display_commit_mode() seems to have intention of returning
the value through the parameter that is only a single pointer.
This causes only the local copy of the pointer, the one inside
display_commit_mode(), to be overwritten.
Let's fix that!
Also add missing hires crc comparison (M. Kahola).
v2: make display_commit_mode return just the last CRC
v3: Don't do memory allocations, it's hard. (Maarten)
v4: Use igt_pipe_crc_collect_crc() instead, cleans up crc handling a lot.

We tried to allow very large buffers (larger than the mappable aperture)
to be flippable by allowing them to be bound into the unmappable region.
Sadly, not all of our hw is capable of utilising the unmappable region for
scanout (and on some older hw, there is only mappable). As such, we have
to allow the very large bo to either succeed in being flipped, or fail
with the expected E2BIG.

On Haswell, at least, MI_REPORT_PERF_COUNT is not flushed by the
PIPECONTROL surrounding the batch. (In theory, before the breadcrumb is
updated the CPU's view of memory is coherent with the GPU, i.e. all
writes have landed and are visible to userspace. This does not appear to
be the case for MI_REPORT_PERF_COUNT.) This makes it an unreliable
method for querying the timestamp, so use MI_STORE_REGISTER_MEM instead.

Bunch of neat improvements:
- xml generates correctly depend upon the test binaries
- no need to re-run autogen.sh when new chapters/functions get added,
all handed by meson
Still one issue:
- the gtkdoc target doesn't depend upon the custom_target yet, hacked
around using build_by_default: true
This is an issue known to upstream already:
https://github.com/mesonbuild/meson/issues/2148
v2: Bump meson version to 0.42, since that's the first release which
adds the build dir when running the gtkdoc tools, and hence allows
including generated files.
v2:
- Undo the bump, it's only needed for generated source files. Other
generated files as input should work with 0.40 already.
- Generate version.xml from version.xml.in, which allows us to keep
the &version; entity.
v3: Add github issue link.
v4:
- Resurrect lost KEYWORDS (Petri)
- Fix issue when running with a clean build, files() doesn't work on generate

CI doesn't run in whole-test mode, but runs each subtest individually.
Tests that are designed to do a block of work to be shared between many
subtests end up running that work multiple times (once per subtest) and
worse, that work is wasted if the subtest will be skipped.
pm_rc6_residency is one such example that measured all the residencies
up front before skipping, each skip was therefore taking in excess of
10s.
v2: Put a small delay back before starting measurements as rc6 doesn't
start until an evaluation interval after idling.
v3: Drop rc6p+ tests; we have no control over the hw whether it decides
to use rc6 or deeper (we can enable it, but not dictate it).

Record the before/after semaphore-wait values around the sleep to try to
reduce the inaccuracy from scheduler delays. Previously, the samples
were taken before submitting the batch and then after synchronising its
completion. The measurement will then be the total that the semaphore
was being sampled, but with the extra syscalls intervening may have
drifted from the sleep duration. To further reduce the disparity, wait
for the batch to start executing before taking our samples.
