Some tests don't use the /tmp temporary files and store it locally in
the test directory. To support NFS this needs to be created by a few
commands. To avoid accidental breakage add a convenience helper.

While testing some changes to how we reclaim block groups I started
hitting failures with my TEST_DEV. This occurred because I had a bug
and failed to properly remove a block groups free space tree entries.
However this wasn't caught in testing when it happened because
btrfs check only checks that the free space cache for the existing block
groups is valid, it doesn't check for free space entries that don't have
a corresponding block group.
Fix this by checking for free space entries that don't have a
corresponding block group. Additionally add a test image to validate
this fix.

When adding the GC support I noticed we were failing fsck when we had a
directory that hadn't been cleaned up yet because of rm -rf. However
this isn't limited to extent-tree-v2, we'll actually fail in the same
way if we were unable to do the evict portion of the deletion and left
the orphan items around for everybody.
This is a valid file system, it'll be cleaned up properly at mount time,
so fsck shouldn't fail in this case.

- Partially written preallocated extents (no data csum for part of the
extent)
- Regular data extents (with data csum)
- Regular data extents then hole punched (with data csum)
- Preallocated data, then written, then hole punched (with data csum)
- Compressed extents (with data csum)

There's a report that a read-only subvolume with a received_uuid set
emits the warning in command 'btrfs subvolume show', which is obviously
wrong.
The reason is that there are different types of root item flags,
depending on how we read them. The check in cmd_subvol_show uses the
ioctl GET_SUBVOL_INFO and the appropriate flag is raw
BTRFS_ROOT_SUBVOL_RDONLY (0x1), while there's another SUBVOL_GETFLAGS that
maps the flags and the raw value is different (BTRFS_SUBVOL_RDONLY, 0x2).
Due to this the warning was issued. Fix that by using the right flag
constant. The test has been extended to check for all combinations of
read-write and received_uuid.

Test case misc/038 uses hard coded backup slot number, this means if we
change how many transactions we commit during mkfs, it will immediately
break the tests.
Such hard coded tests will be a big pain for later btrfs-progs updates.
Update it with runtime backup slot search.
Such search is done by using current filesystem generation as a search
target and grab the slot number.
By this, no matter how many transactions we commit during mkfs, the test
case should be able to handle it.

Relax the condition about a unique uuid for convert, only print a
warning. In case we copy the uuid, it's expected that at the time the
conversion starts the uuid is not unique as it sill exists on the source
filesystem.
In case user sets the uuid manually but it's still the same one as on
the source filesystem we should also allow that, so it warns in this
case as well.
Update the test so it creates a block device where the uuid would be
also cached by blkid and lets the non-unique check succeed.

Although btrfstune will already warn users to make sure the fs is not
corrupted, we can never trust end users.
If the target fs has transid error, btrfstune can cause further damage,
thus we need to make sure btrfstune can safely reject fs with transid
error, other than ignoring the problem.
