Instead of always blindly picking the matching supp codec for the
receiver codec, pick it only if there is no appropriate sink supp codec,
or both are compatible (which implies a payload type mismatch).

Move o= replacement logic into sdp_out_add_origin. Copy fields from
input source ML if present, or keep unchanged. Generate if not present.

This is needed to correctly print media labels for SIPREC in case the
input SDPs already had media labels.

The `created_from` address string includes the port, which must be
removed when substituting it for the RPC URL.

For a repeated subscribe-request on an existing monologue, make sure
that existing media sections are re-used for the same subscriptions as
they were previously, and only create new ones in an append-only fashion
for media subs which didn't previously exist.

New NG protocol commands that mix audio from a source participant
into a destination participant's stream without a full offer/answer
exchange.
- inject start: creates one-way subscription with audio_player mixing
- inject stop: removes injection and restores original codec routing
- Supports cross-call injection via source-call-id (merges calls internally)
- inject attribute persisted through Redis for HA failover
- Audio-only; matches media by media-id, index, then type fallback

Provide an extra codec-store for the lookup of the answer codec. This is
needed for codec switches during an extra answer, as the original codecs
are kept in a different codec-store.

Use a pointer to the arena plus a comparison test to determine whether
to ref or to dup the string, instead of a function pointer. The function
pointer alone wasn't enough as there can be multiple arenas.

The Kamailio control module unconditionally adds the current to-tag to
the control message if rtpp-flags parsing is active. This is generally
not desirable in the case of an initial subscribe-request, as we want a
generated to-tag when the existing to-tag belongs to another dialogue.
Special-case this to ignore the included to-tag if none has been given
explicitly.
