Since our goal is to have concurrent read/writes of GPU buffers, we want
to spend as little time in between as possible.

i-g-t: Adding plane scaling test case
introduced a condition where it attempts to update a disabled plane because
of the newly introduced size_changed flag which is set for disabled frame
buffers. Result is a NULL ptr deref in igt_drm_plane_commit (plane->fb->src_x).
Start recognising this case as disabled plane and act accordingly.

New subtests to excercise flips from tiled to tiled and from
linear to tiled frame buffers.
These will catch display programming issues like not preserving the
tiling mode in page flips or not re-programming the watermarks.
v2: Cleanup crc object after failing subtests.
v3:
* Wait for page flip completion instead of vblank. (Chris Wilson)
* Added linear->tiled flip tests to catch watermark programming issues.
v4:
* Refactored for less code.
* Check crc after page flip to ensure it happened. (Chris Wilson)
* Skip rather than fail when flip fails. (Chris Wilson)

Use the first pass to write all values prior to the initial execbuf to
verify that the copy itself is true. Subsequent passes then focus on
verifying that writing values whilst the GPU is reading from
neighbouring values is then correct.

For all those IGT tests that need an easy way to draw rectangles on
buffers using different methods. Current planned users: FBC and PSR
CRC tests.
There is also a tests/kms_draw_crc program to check if the library is
sane.
v2: - Move the test from lib/tests to tests/ (Daniel).
- Add igt_require() to filter out the swizzling/tiling methods we
don't support (Daniel).
- Simplify reloc handling on the BLT case (Daniel).
- Document enum igt_draw_method (Daniel).
- Document igt_draw_get_method_name() (Paulo).
v3: - Add IGT_DRAW_MMAP_WC (Chris).
- Implement the other trivial swizzling methods (Chris).
- Remove the gem_sync() calls (Chris).

Commit 47f6b1305cc3752f318a555b932e194e1500c1d8 completely broke this
test due to the fread() assertion. When we're reading the debugfs file
we really don't care about how many bytes we read because the number
is not constant and we just use strstr() later. Change the assertion
to make it check for at least 1 byte read, just to make sure no one
changes that again.

While it is nice to have shorter names for the most-accessed
variables, it makes the code more difficult to read since it's not
clear to the code reader whether that "gem_handle" is from some FB or
something else. The reader also has to audit the code to see if, for
example, the value of data->handle[0] stays consistent with
data->fb[0].gem_handle all the tame or if at some point the value is
replaced with something else. So remove the redundant information,
making it explicit that we're using the gem handles and FB IDs of the
framebuffers all the time.

The code has a common pattern of "wait 300ms, then check if FBC is
enabled". Most of the time FBC is enabled in either 50ms or 0ms, so
introduce wait_for_fbc_enabled(), which can return much earlier if FBC
is actually enabled before the 300ms timeout.

Just a little helper for code that needs to wait for a certain
condition to happen. It has the nice advantage that it can survive the
signal helper.
Despite the callers added in this patch, there is another that will go
in a separate patch, and another in a new IGT test file that I plan to
push later.
v2: Check COND again before returning in case we hit the timeout.

The call to low_mem_killer_disable(true) was being done
from within function oom_adjust_for_doom. However,
oom_adjust_for_doom gets called from 3 places. We only
want the call to low_mem_killer_disable(true) to happen
during common_init, so call it from here instead of from
oom_adjust_for_doom.
v2:Thomas Wood pointed out that the initial call to disable
the low_mem_killer does not get made when we are just
listing subtests; so I have qualified the call from the
exit handler, which re-enables the low_mem_killer, with
if (!igt_only_list_subtests()).
For belt and braces I have also made low_mem_killer_disable
idempotent, so multiple calls to disable or re-enable are
safe.

Test used to call prepare_crtc twice in the plane loop and leaked two
framebuffers per [subtest]x[pipe]x[plane].
What the loops really wants to do, instead of second invocation of
prepare_crtc, is to just turn on the display with the unrotated fb to
verify that the plane property has been restored by the VT transition
from previous to graphics mode.
To enable that factor out code which does that from prepare_crtc into
commit_crtc and call it instead.
