[Serusers] New save_noreply() function for the registrar module

[Maxim Sobolev]

Folks,

We found that in some cases it is necessary to have a function which
will save contact without sending reply to the UA. For example, it is
useful when there is a need to do stateless forwarding of the REGISTER
request, but at the same time save it in the local registration
database (sending reply in this case will disable any retransmissions
that might be necessary to ensure that the request actually reached the
destination). Attached patch provides necessary functionality, it would
be nice to have it included into the next release.

Thanks!
