Wang Shilong e5f72de944 Btrfs-progs: chunk-recover: use right size when allocating chunk root node 
When allocating chunk root node, we should use nodesize rather than sectorsize,
this will casue regression when making other nodesize choice.(for example 16k size now)

Ross Kirk 7ff512ce38 btrfs-progs: Make btrfs_header_chunk_tree_uuid() return unsigned long 
Internally, btrfs_header_chunk_tree_uuid() calculates an unsigned
long, but casts it to a pointer, while all callers cast it to unsigned
long again.

Wang Shilong 77801d34d0 Btrfs-progs: pass flag to control whether run ioctl in btrfs_scan_for_fsid() 
If some fatal superblocks are damaged, running ioctl will return failure,
in this case, we should avoid run ioctl.

David Sterba e9270f6209 btrfs-progs: separate command and implementation of chunk-recover code 
The command has been moved and we should rename the files accordingly,
so the entry point is now in cmds-rescue.c and the core functionality
in it's own file.

Return codes of btrfs_recover_chunk_tree have been simplified not to
require a define and another file for defintion.
