KDC on Tru64 was hanging because of another case where Yarrow code
assumes locks are recursive.  Probably didn't trigger on Linux,
Solaris, or NetBSD because they have /dev/random and Tru64 does not.

* yarrow.c (yarrow_input_maybe_locking): Renamed from
yarrow_input_maybe_locking, made static.  New argument indicates whether or not
to do locking.
(krb5int_yarrow_input): New wrapper function.
(yarrow_input_locked): New wrapper function.
(Yarrow_detect_fork): Call yarrow_input_locked.
