ChangeLog, journal.c, problem.c, problem.h:
  problem.c, problem.h: Change PR_0_JOURNAL_UNSUPP_INCOMPAT and
  	PR_0_JOURNAL_UNSUPP_ROCOMPAT so they aren't fatal errors, but prompt
  	to see if the user should abort.  Removed the
  	PR_0_JOURNAL_RESET_COMPAT problem code.
  journal.c (e2fsck_journal_load): If there are incompatible journal
  	flags, just return an error code.
  	(e2fsck_check_ext3_journal): If e2fsck_journal_load returns an error
  	code indicating that there are incompatible journal flag, check to see
  	if we should abort, and then offer to clear the journal.
