This patchset provides tests for fsverity support in btrfs.

It includes modifications for generic tests to pass with btrfs as well
as new tests.

- use nodatasum for btrfs corruption tests.
- modify eof block corruption test to allow all zeroes rather than
  requiring an error.
- reorganize to have a patch for enabling generic tests followed by the
  patches with new and specific tests.
- fix some rebasing miscues from v7.
- fix a chunk of space characters instead of a tab in the new requires
- add a new patch to make the new corruption requires more clear
- require corruption in generic/576
- require only btrfs_corrupt_block in btrfs/290
- add missing xfs_io requirements in btrfs/290
- remove unneeded zero byte check from btrfs corruption function
- fix sloppy extras in generic/690
- refactor "requires" for verity corruption tests so that other verity
  tests can run on btrfs even without the corruption command available.
  Also, explictly require xfs_io fiemap for all corruption tests.
- simplify and clarify "non-trivial EFBIG" calculation and documentation
  per suggestions by Eric Biggers.
- remove unnecessary adjustment to max file size in the new EFBIG test;
  the bug it worked around has been fixed.
- more idiomatic requires structure for making efbig test generic
- make efbig test use truncate instead of pwrite for making a big file
- improve documentation for efbig test approximation
- fix underscores vs dashes in btrfs_requires_corrupt_block
- improvements in missing/redundant requires invocations
- move orphan test image file to $TEST_DIR
- make orphan test replay/snapshot device size depend on log device
  instead of hard-coding it.
- rebase (signicant: no more "groups" file; use preamble)
- mark local variables
- get rid of redundant mounts and syncs
- use '_' in function names correctly
- add a test for the EFBIG case
- reduce usage of requires_btrfs_corrupt_block
- handle variable input when corrupting merkle tree
v3: rebase onto xfstests master branch
v2: pass generic tests, add logwrites test
