This patchset will do the following bug fix mostly on incorrect flags.
1) INCONSISTENT flag never cleared bug
2) RESCANNING flag never cleared unless umount.
Also add 2 qgroup level related checks:
1) Kernel check on qgroup assign to ensure dst's level is higher than
src.
2) Restrict qgroup id under 1<<48, to ensure qgroup id won't have level
higher than 1.
At last, add semi-automatic qgroup info update on relationship assign.
The automatic part only happens when all extents of src are exclusive.
If not, it will set INCONSISTENT flag and return >0 to info user land
progs to do rescan.
