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

For the incoming extra page size support for subpage (sectorsize <
PAGE_SIZE) cases, the support for metadata will be a critical point.
Currently for subpage support, we require 64K page size, so that no
matter whatever the nodesize is, it will be contained inside one page.
And we will reject any tree block which crosses page boundary.
But for other page size, especially 16K page size, we must support
nodesize differently.
For nodesize < PAGE_SIZE, we will have the same requirement (tree blocks
can't cross page boundary).
While for nodesize >= PAGE_SIZE, we will require the tree blocks to be
page aligned.
To support such feature, we will make btrfs-check to reports more
subpage related warnings for metadata.
This patch will report any tree block which is not nodesize aligned as a
warning.
Existing mkfs/convert has already make sure all new tree blocks are
nodesize aligned, this is just for older converted filesystems.

For fsck tests, we check the subpage warnings for each type 1 test, but
such type 1 tests are mostly read-only tests, and one of the test will
trigger new subpage related warnings (fsck/018).
For subpage related warnings, what we really care are write operations,
including mkfs, btrfs-convert and repair, not those read-only tests.
So skip the subpage warning check for fsck type 1 tests to prevent false
alert of later more strict subpage warnings.

There are two types of test cases:
- Type 1 (without test.sh)
- Type 2 (test.sh, mostly will override check_image())
For Type 2 tests, we check subpage related warnings of btrfs-check, but
didn't check it for Type 1 test cases.
In fact, Type 1 test cases are more important, as they involve repair,
which can generate new tree blocks, and we want to make sure such new
tree blocks won't cause subpage related warnings.
This patch will add the extra check for Type 1 test cases.
And it will make sure the subpage related warnings are really from this
test case, to prevent false alerts.

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.

Add a runtime feature (-R) flag for the free space tree. A filesystem
that is mkfs'd with -R free-space-tree then mounted with no options has
the same contents as one mkfs'd without the option, then mounted with
'-o space_cache=v2'.
The only tricky thing is in exactly how to call the tree creation code.
Using btrfs_create_free_space_tree as is did not quite work, because an
extra reference to the eb (root->commit_root) is leaked, which mkfs
complains about with a warning. I opted to follow how the uuid tree is
created by adding it to the dirty roots list for cleanup by
commit_tree_roots in commit_transaction. As a result,
btrfs_create_free_space_tree no longer exactly matches the version in
the kernel sources.
