The clear-cache functionality is shared by several commands:
- btrfs check
For --clear-cache and --clear-ino-cache.
- btrfstune
Mostly for block-group-tree feature conversion.
- btrfs-convert
To enable the now default v2 space cache.
Thus it's no longer proper to keep clear-cache.[ch] under check/
directory, move them to common/ directory.
