Per RFC 4867 section 8.1, absent fmtp parameters imply defaults (bandwidth-efficient mode, no CRC,
no robust-sorting, no interleaving). Previously, codec matching was rejected when either side had no
``a=fmtp`` attribute for the AMR payload type, causing AMR to be dropped as a "stray answer codec".
This patch changes this behavior to instead "parse" fmtp even when absent so that the format struct
is populated with zero-initialized defaults and fmtp_parsed is set.

Previously, the ports used for a monologue subscription would leak upon re-subscribe.
``__assign_stream_fds`` cleared the stream fd queue without decrementing the ref count. This
prevented ``monologue_destroy`` from releasing the ports on unsubscribe.

It doesn't make sense to produce an answer SDP with ICE attributes (and
enabling ICE processing) if the offer didn't indicate ICE support.

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.

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

Instead of opening local sockets directly during call setup, just create
the appropriate objects first, and then open the actual sockets in a
second step.
Move the opening step down, after the bundle logic has run. This way we
can avoid opening sockets that aren't needed.
Removes an intermediate step of obtaining consecutive ports.
