It might be useful to know whether or not there has been any problem during the check. This commit add new variable problem_history into e2fsck_struct in order to store error codes. When problem occur and fix_problem() is invoked, problem code is stored into problem_history. Note that only real problem are stored, hence problems with PR_NO_PROBLEM are ignored. This commit also adds PR_NO_PROBLEM flag into problem for informative purposes only.
