Both lowmem and original mode should be able to detect and fix it.
The extracted test image is pretty big (1G extracted), as kernel won't
cache small chunks.
Even with SSD, such test may still take some seconds just extracting the
image.

Add a test for a scenario that used to fail due to find_mount_root()
incorrectly determining the mount point for the receive path due to the
fact that a different mount point with a path that is a prefix of the
receive path exists.

The runtime of the test is over 4 minutes when hosted on NFS, the
fallocate phase takes the most time. As fallocate can't take multiple
arguments, we can't save the overhead by creating the files at once.
Create the files in batches in the background, this improves the runtime
to 2 minutes.

Now two locations can detect such problem, either by device item
used/total bytes check, or by early dev extents check against device
boundary.
The image is hand-crafted image which uses DATA SINGLE chunk to feed
btrfs check. As expected, as long as block group item, chunk item,
device used bytes match, older versions check can't detect such problem.

Test case misc/021 is testing if we could mount a single disk btrfs
image recovered from multi disk fs.
The problem is, current kernel has extra check for block group, chunk
and dev extent. This means no image can pass btrfs check for chunk
tree and the filesystem will not mount.
So do extra btrfs check before mount, this will also help us to locate
the problem in btrfs-image easier.

For trees have been balanced, leaves are with flag BTRFS_HEADER_FLAG_RELOC and
extent data backrefs are shared. Like:
=====================
item 0 key (11927552 EXTENT_ITEM 524288) itemoff 3932 itemsize 63
refs 129 gen 7 flags DATA
shared data backref parent 35897344 count 41
shared data backref parent 35426304 count 37
shared data backref parent 35422208 count 51
=====================
Then make the leaf which owns the extent data cowed. The shared data
backref was to transferred to keyed data ref, but remaining backrefs are
still shared. Like:
=====================
item 0 key (11927552 EXTENT_ITEM 524288) itemoff 3887 itemsize 108
refs 129 gen 7 flags DATA
extent data backref root 5 objectid 258 offset 0 count 40
extent data backref root 5 objectid 257 offset 0 count 1
shared data backref parent 35426304 count 37
shared data backref parent 35422208 count 51
=====================
However lowmem mode used to iterate the whole inode to find all
references, and doesn't care if a reference is already counted by the
shared tree block.
Add the test case to check it.
