  Modified files:        (Branch: RELENG_4)
    usr.bin/login        login.c 
  Log:
  MFC Rev 1.66:
  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.
  
  MFC Rev 1.67:
    Fix some bogus strncpy(3) to strlcpy(3) changes I made in the previous
    revision.  <utmp.h> structures don't leave room for a NUL character.
    Also fix "UNKNOWN" which should have just been UNKNOWN.
