As this requires a patched GNOME Contacts, we want to be able to query if the
necessary actions to add new contacts is available before trying to use it.
Not all portions from the user interface are listening directly to messages from
accounts, so the manager should propagate them to allow the UI to pick them up.
Closes#340
Introduce a state-changed signal which also gives a reason for why the state
changed. This will allow the UI to give some meaningful feedback to the user.
Additionally we can get rid of a number of things that were not really states,
but rather reasons for why a state changed (f.e. authentication failures).
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
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.

If the origin is used for PSTN telephony extract the number from the
SIP dialstring (i.e. sip:+49160123456789@my-sip-host.de) and pass that
to call object for contact matching.
