Maintain pw_fields, and output same to password database.

Browse Source 
!!!!!!!!
NB
!!!!!!!!
You MUST pwd_mkdb /etc/master.passwd before attempting to use the new
libc, or things may go wrong.  (I doubt anything actually /will/ go
wrong, but the actual behavior is undefined.  YOU HAVE BEEN WARNED.)
The database format is, however, backwards-compatible, so old executables
will still work.
