Originally only if 'block_only' is specified, the 'fs_root == NULL'
will be checked. But if 'block_only' is not specified and close_root
will be called blindly without checking 'fs_root == NULL', which is
unsafe.

we use 37 as the allocation size to hold the uuid_unparse, here
it defines BTRFS_UUID_UNPARSE_SIZE for the same.

So I needed to add a flag to not try to read block groups when doing
--init-extent-tree since we could hang there, but that meant adding a whole
other 0/1 type flag to open_ctree_fs_info. So instead I've converted it all
over to using a flags setting and added the flag that I needed. This has been
tested with xfstests and make test. Thanks,

In some cases the tree root is so hosed we can't get anything useful out of it.
So add the -b option to btrfsck to make us look for the most recent backup tree
root to use for repair. Then we can hopefully get ourselves into a working
state. Thanks,

Port of commit b3b4aa7 to userspace.
parameter tree root it's not used since commit
5f39d397dfbe140a14edecd4e73c34ce23c4f9ee ("Btrfs: Create extent_buffer
interface for large blocksizes")
This gets userspace a tad closer to kernelspace by removing
this unused parameter that was all over the codebase...

For any btrfs-$FOO executable, rename the main source file from
$FOO.c to to btrfs-$FOO.c
This makes it slightly more obvious what's building what,
and allows us to write a default rule in the Makefile for
these tools.
(also add btrfs-calc-size to the list of objects to remove
on make clean)
