a99755424f media-manager: Don't run deinitialize GStreamer in finalize() 
This makes running tests harder as we cannot call gst_init() after gst_deinit()
has been called.

This is what the API reference has to say about it at
https://gstreamer.freedesktop.org/documentation/gstreamer/gst.html?gi-language=c#gst_deinit

It is normally not needed to call this function in a normal application as the
resources will automatically be freed when the program terminates. This function
is therefore mostly used by testsuites and other memory profiling tools.

876f12df95 sip: media-manager: Don't include sofia-sip/nua.h in public header 
It isn't needed in the implementation either. It was only useful because it
included system headers like sys/types.h and sys/socket.h which we should now
include directly.

This will make it easier to move the media manager into the core sources.

cdb6f90acc account: Rework account states 
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).

38f9e0b608 sip: media-manager: Get rid of global session IP

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

   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
