We need to make sure we process the block group root, and mark its
blocks as used for the free space tree checking.

The fuzz-test/003 was infinite looping when I reworked the code to
re-calculate the used bytes for the superblock. This is because fsck
wasn't properly fixing the bad extent before my change, it just happened
to error out nicely, whereas my change made it so we go the wrong bytes
used count and just infinite looped trying to fix the problem.
Fix this by sanity checking the extent when we try to re-calculate the
bytes_used. This makes us no longer infinite loop so we can get through
the fuzz tests.

We could have multiple extent roots, so add a helper to mark all the
used space in the FS based on any extent roots we find, and then use
this extent io tree to fixup the block group accounting.

When we switch to multiple global trees we'll need to access the
appropriate extent root depending on the block group or possibly root.
To handle this, use a helper in most places and then the actual root in
places where it is required. We will whittle down the direct accessors
with future patches, but this does the bulk of the preparatory work.

btrfs_mark_used_tree_blocks skips the reloc roots for some reason, which
causes problems because these blocks are in use, and we use this helper
to determine if the block accounting is correct with extent tree v2.

This is going to be used for the extent tree v2 stuff more commonly, so
move it out so that it is accessible from everywhere that we need it.

We have this helper sitting in extent-tree.c, but it's a repair
function. I'm going to need to make changes to this for extent-tree-v2
and would rather this live outside of the code we need to share with the
kernel.

Move the file to common as it's used by several parts, while still
keeping the name 'repair' although the only thing it does is adding a
corrupted extent.
