Add tests that perform panning / page flip operations on an fbdev
device. Panning should work when the viewport wi within the virtual
screen and fail otherwise.
v4:
* return early if PAN ioctl failed in pan_test()
v3:
* moved ioctls and assertions into helper (Ville)
* set FB_VMODE_YWRAP for rsp tests
* additional comments on YWRAP
v2:
* set offset to respect panning offsets (Ville)
* respect FB_VMODE_YWRAP (Ville)

The last unaligned test, looks for the target character in the tail of
the buffer, where it is not expected to be found. We should be asserting
that the memchr() returned NULL.

Trying to read and write with a NULL-pointer buffer should fail and
report EFAULT.
v6:
* actually replace igt_require() (Petri)
v4:
* replace igt_require() by igt_assert() in "nullptr" (Petri)
* add nullptr test to CI
v3:
* put igt_describe() before igt_subtest() (Petri)

Fbdev has some specific behavior when reading/writing near the EOF, which
the eof test checks. If at least one bytes has been written, the number
of bytes has to be returned, otherwise an error code (if any) has to be
returned, or otherwise 0 has to returned. Not all drivers get this right.
v4:
* replace igt_require() by igt_assert() in "eof" (Petri)
* add eof test to CI
v3:
* put igt_describe() before igt_subtest() (Petri)
