e2fsck: add -m option for multithread
-m option is added but no actual functionality is added. This
patch only adds the logic that when -m is specified, one of
-p/-y/-n options should be specified. And when -m is specified,
-C shouldn't be specified and the completion progress report won't
be triggered by sending SIGUSR1/SIGUSR2 signals. This simplifies
the implementation of multi-thread fsck in the future.
Completion progress support with multi-thread fsck will be added
back after multi-thread fsck implementation is finished. Right
now, disable it to simplify the implementation of multi-thread fsck.
