This will make sure that we're not using a stale IP address if we're resetting
the account after an IP change.

38f9e0b608 sip: media-manager: Get rid of global session IP
Since we're now passing the IP to be used to retrieve the capabilities
for the SDP message body, this has become dead code.

8b126484cb sip: Use per origin IP instead of a global IP
Sofia detects a NAT by presence of the "received" parameter in the Via header in
the response to a REGISTER. Sofia will then update the Contact header to use the
IP as reported by the registrar.

The "received" parameter MUST be included in the response according to
https://datatracker.ietf.org/doc/html/rfc3261#section-18.2.1
when the registrar detects a difference between the domain part of the top Via
header and the packet source address but practice has shown that this will not
always be the case.

Addditionally this change allows us to have origins bound to different network
interfaces which would be useful when a registrar can only be accessed through a
VPN.

This also fixes an issue with SDP introduced in
36880c3d34 which was only seen on some SIP
providers:

The session name ("s=") line is not relevant for establishing a connection,
the connection data (c=") line is.

See https://datatracker.ietf.org/doc/html/rfc4566 section 5.3 and 5.7

ba00665c36 sip: origin: Decouple TLS usage from target address
Since we cannot do encrypted media streams yet, we should hardcode whether or
not we want to use SRTP to FALSE, so that sips target URLs can be used in SIP
calls at all.

Otherwise we might miss the IP of the remote peer leaving us unable to
establish a connection for RTP.

From https://datatracker.ietf.org/doc/html/rfc4566#section-5.7

   A session description MUST contain either at least one "c=" field in
   each media description or a single "c=" field at the session level.
   It MAY contain a single session-level "c=" field and additional "c="
   field(s) per media description, in which case the per-media values
   override the session-level settings for the respective media.

The assumption that the IP of the remote peer can always be found in the

16897eebe6 sip: origin: Include transport parameter in NUTAG_URL and friends
This makes sure all of the supported protocols have a chance of working.

Since nua_set_params does not update NUTAG_URL (carefully rechecking the docs
verifies this), it is safe to remove the code in update_nua().

However, this means that we will have to recreate the nua stack,
which incidentally is currently being worked on:
