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.

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.
The image is copied from fsck-tests/002, just override check_image() to
run "btrfstune -u" instead.

The current mount detection code in btrfs receive is not quite perfect.
For example, suppose /tmp is mounted as a tmpfs. In that case,
btrfs receive /tmp2 will find /tmp as the longest mount that matches a
prefix of /tmp2 and blow up because it is not a btrfs filesystem, even
if /tmp2 is just a directory in / mounted as btrfs.
Fix this by replacing the substring check with a dirname recursion to
only check the directories in the path of the dir, rather than every
substring.
Add a new test for this case.

Since run_check_stdout() can insert INSTRUMENT for all btrfs related
programs, which could easily pollute the stdout, any caller of
run_check_stdout() should do proper filter.
The following callers are affected:
- misc/004
Filter the output of "btrfs ins min-dev-size"
- misc/009
- misc/013
- misc/024
They are all calling "btrfs ins rootid", so introduce get_subvolid()
function to grab the subvolid properly.
- misc/031
Loose the filter for "btrfs qgroup show". No need for "tail -n 1".
So we still have the same coverage, but now these tests won't cause
false alert if we insert INSTRUMENT for all btrfs commands.

As seem in issue #192, this test can fail from time to time. The
issue happens when a mount is issued before the new device is processed
by systemd-udevd, as we can see by the og bellow:

A few moments after the test failed systemd-udevd processed the new
device (registered the new device under btrfs). This can be tested by
executing a mount after the test failed, resulting in a successful
mount:
$ mount /dev/loop10 /mnt

This problem can be avoided is we execute "udevadm settle" before the
mount is executed.

As misc-tests/021 image dump is restored on the same original loop

Fix this by using a new device for restore.
And also, the btrfs-image dump and restore doesn't restore the file
