[PATCH 00/16] btrfs-progs: Split lowmem mode check to its own

[Qu Wenruo <wqu@suse.com>]

The long planned cmds-check re-construction is finally here.

As the original cmds-check.c is getting larger and larger (already over
15K lines), it's always a good idea to split it into its own check/
directory.

This patchset do the following work:
1) Move cmds-check.c to check/main.c
2) Put codes shared by both original and lowmem mode into
   check/common.[ch]
3) Put lowmem code into check/lowmem.[ch]
   With minor renaming to get rid of unnecessary _v2 suffix.

The modification looks scary, but no functional change at all.

And considering how much the file structure changed, it's a good idea to
put PART1 as quick as possible, and there will be less pressure to
rebase new incoming fsck related codes.

The real move work happens in the 15th patch, which due to its size
(500KB+), it may not be able to reach mail list.
So please fetch the whole patchset from github:

There will be a part 2, mostly moving original mode to its own
check/original.[ch], along with extra comment explaining how the two
different modes work.
