[v4,0/3] fstests: copy_file_range() tests

Eryu,

These are the two remaining copy_file_range() tests which
I used to verify the kernel fixes that are now in master [1].

The bounds check test depends on an xfs_io change that was merged to
xfsprogs v5.1.0-rc1 (copy_range -f).

The cross-device copy test checks a new functionality, so it does
_notrun if copy_range return EXDEV instead of failing.

Thanks,
Amir.

Changes from v3:
- swapfile and immutable file tests already merged (generic/55[34])
- Use an actual loopdev owned by this test
- Use /dev/null and /dev/zero and char devices for test
- _notrun if cross-device copy_range return EXDEV

Changes from v2:
- Change blockdev in test to loop and _require_loop (Olga)
- Implement and use _require_xfs_io_command copy_range -f

Changes from v1:
- Remove patch to test EINVAL behavior instead of short copy
- Remove 'chmod -r' permission drop test case
- Split out test for swap/immutable file copy
- Split of cross-device copy test
