These were mostly in option structs but there were a few gross string
pointer arguments given as 0.

With -w one can wait for a rescan operation to finish. It can be used when
starting a rescan operation or later to wait for the currently running
rescan operation to finish. Waiting is interruptible.

valgrind complains open_file_or_dir() causes a memory leak.That is because
if we open a directoy by opendir(), and then we should call closedir()
to free memory.

This adds the quota rescan command to be used if qgroup tracking should get
out of sync. Can also be used to query the status of a running rescan
operation.

Extending usage messages with some info on the quota functionality:
- The -i option of "subvol create" and "subvol snapshot" was not
documented
- The -c option of "qgroup limit" is the default option
- The "qouta rescan" command is not yet implemented, while it should be
executed after enabling quota on a non-empty filesystem.

The definition of the function open_file_or_dir() is moved from common.c
to utils.c in order to be able to share some common code between scrub
and the device stats in the following step. That common code uses
open_file_or_dir(). Since open_file_or_dir() makes use of the function
dirfd(3), the required XOPEN version was raised from 6 to 7.
