  mid_registrar: Add the "o" save() flag

The "o" flag will cause 200 OK replies to REGISTER requests to "Only
include request contacts".  Technically speaking, this is against RFC
3261, § 10.3, (8), which says:

      8. The registrar returns a 200 (OK) response.  The response MUST
         contain Contact header field values enumerating all current
         bindings.  Each Contact value MUST feature an "expires"
         parameter indicating its expiration interval chosen by the
         registrar.  The response SHOULD include a Date header field.
