Modified files:
usr.bin/login login.c
Log:
o Replace occurrences of strncpy(3) with strlcpy(3); most of
the uses of it were wrong anyway.
o Always check for NULL returns on strdup(3).
o Fix a possible buffer overflow in strcpy(3).
o Fix a format string vulnerability.
o t->ty_type in stypeof() could be NULL and eventually cause
a segmentation fault in setenv(3), so check for that.
