Enable checking:
maxrepeat - reject passwrods which contain more than N consecutive
characters.
maxsequence - rejected passwords which contain character sequences
(abcde).
dictcheck - check passwords using cracklib
usercheck - check whether the password contains the user name.
The class checking provided by libpwpolicy is not used because this
overlaps with the existing IPA checking. This includes the options
dcredit, ucredit, lcredit, ocredit, minclass and maxclassrepeat.
The pwquality min length is fixed at 6 so if there is a conflict between
the system policy and pwquality log that length is enforced at 6.

The man page for qsort(3) says that the comparison function is called
with pointers to pointers to char but memcmp(3) wants a pointer to void
so we need to cast and dereference.
Without this the qsort() call wasn't properly sorting the elements so
a random password was being removed rather than the oldest when the
list overflowed.

User always receives the same error message if he changes his password
via "ipa passwd" command and the new password fails configured
password policy. He then has to investigate on his own the actual
reason why was the policy violated. This patch improves our SLAPI PWD
plugins to provide a better error message explaining the violation
reason.
