test_minimum_size() function is only called to check if provided device
is large enough.
However the minimal device size only needs to be calculated once, and
can be reused everywhere.
Refactor that function to make later modification easier.

--rootdir option will start a transaction to fill the fs, however if
something goes wrong, from ENOSPC to lack of permission, we won't commit
the transaction and cause BUG_ON triggered by uncommitted transaction:
------
extent buffer leak: start 29392896 len 16384
extent_io.c:579: free_extent_buffer: BUG_ON `eb->flags & EXTENT_DIRTY` triggered, value 1
------
The root fix is to introduce btrfs_abort_transaction() in btrfs-progs,
however in this particular case, we can workaround it by force
committing the transaction.
Since during mkfs, the magic of btrfs is set to an invalid one, without
setting fs_info->finalize_on_close() the fs is never able to be mounted.
So even we force to commit wrong transaction we won't screw up things
worse.

For mkfs failure, especially --rootdir errors like EPERM/ENOSPC, the out
branch will overwrite the return value, causing wrong status code.

Since we're calling btrfs_search_slot() the return value can be
positive. However we just pass that return value out, causing undefined
return value.
This can cause mkfs to return 1, which indicates something wrong.
Fix it.

Mkfs uses make_path that is duplicate of path_cat* functions, so we can
switch to them and add the error handling.

Add an objectid parameter to make the function a general one for
inserting root items and rename it to create_tree. The change cascades
down to the callchain.

[Bug]
If using mkfs.btrfs with "-r" parameter and specified directory has
fifo/socket/char/block special file, then created filesystem can't pass
fsck:
------
checking fs roots
unresolved ref dir 241158 index 3 namelen 9 name S.dirmngr filetype 0 errors 80, filetype mismatch
ERROR: errors found in fs roots
------
[Reason]
Btrfs dir items/indexes records inode type, while "-r" only handles
directories, regular files and symlink, it makes such special files type
to be regular file and caused the problem.
[Fix]
Add missing types for add_directory_items(), so that result of
"mkfs.btrfs -r" can pass mkfs.

Currently transaction bugs out insided btrfs_start_transaction in case
of error, we want to lift the error handling to the callers. This patch
adds the BUG_ON anywhere it's been missing so far. This is not the best
way of course. Transforming BUG_ON to a proper error handling highly
depends on the caller and should be dealt with case by case.

There multiple places where we use well-known sizes - 1,8,16,32 megabytes. We
also have them defined as constants in the sizes.h header. So let's use them.
