The number of rounds and number of salt bytes was fixed to their lower
allowed values (resp. configurable and 8), hence voiding some of the
advantages of this encryption method. Dictionary attacks with
precomputed tables were easier than expected, but still harder than with
the MD5 (or DES) methods.

seedRNG instead of srand, and fix the same overflow. This caused
the number of rounds to always be the smallest one.

password was not changed when pam_chauthtok fails (in addition to
the PAM error, which may not be comprehensible for the users).
