Postgres FD Implementation

Replace use of the long-deprecated Bonjour API DNSServiceRegistrationCreate 

with the not-so-deprecated DNSServiceRegister.  This patch shouldn't change
any user-visible behavior, it just gets rid of a deprecation warning in
--with-bonjour builds.  The new code will fail on OS X releases before 10.3,
but it seems unlikely that anyone will want to run Postgres 8.5 on 10.2.
