lib/pwio.c, lib/pwio.h, lib/shadowio.c, lib/shadowio.h: Added

* src/login.c: Always free the pwd and spwd structure when we
retrieve a new one. This will clear the password of the previous
user from the memory.
* src/login.c: user_passwd is used to keep point to the password
of the user being authenticated.
* src/login.c: (non PAM) Fail if the user's entry cannot be found

* src/faillog.c: Move print_one() closer to print().
* src/faillog.c: reset(), setmax(), set_locktime() can also change

create entries for users which have no entries if the value has to
be set to 0.
* src/faillog.c: reset(), setmax() and set_locktime(): better
handling of users whose entry is outside the faillog file.

utmp.c to chowntty.c. checkutmp() now only uses an existing utmp
entry if the pid matches and ut_line matches with the current tty.
This fixes a possible DOS when entries can be forged in the utmp
