There was a regression in version 5.15 due to changes in how the ratio
for the various raid profiles got calculated and this in turn had a
cascading effect on unallocated/allocated space reported.
Add a test to ensure this regression doesn't occur again.

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.

Since current "btrfs filesystem df" command will warn if there are
multiple profiles of the same type, it's a good way to detect left-over
temporary chunks.

check for the warning messages, to make sure mkfs.btrfs has properly

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.
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.
