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.

With the more modern codec handling, there shouldn't be any more need to
unconditionally remove unsupported codecs if some codecs are requested
for transcoding.

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.

Allow invalid payload types for rejected RTP streams.
Allow empty codec store for zero-port streams.
Has some side effects on tests.

With the newly introduced `ng_command_find()` lookup func.
Add the local `ng_command_def` and maintain via it.
Check whether:
- the handler has been defined
- the handler gets properly selected
- the command is defined (known)
Accordingly update the opmode of the command context.
By default define as `OP_OTHER` always.
For the case when no handler has been defined, introduce
the error reply "No handler found".
Accordingly trigger selected handler after
the command was found.
The main payoff here is that the command processing
flow becomes quite transparent and easy to maintain:
- parse command string
- lookup command definition
- set opmode from table
- call uniform handler
- shared error/success reply handling for all commands
Deprecate strhash based `__csh_lookup()`/`CSH_LOOKUP()`.
Accordingly adap the daemons's and tests Makefile,
remove the strhash objects with the normal control_ng one.
Additionally:
introduce the special `resultstr = "pong"` for the
ping command case, because all other commands have "ok".

Add the 'all' keyword for the codec accept option in publish mode:
- 'all': keep all codecs supported for transcoding and their
supplemental codecs, removing only unsupported ones
- 'all' + 'any': keep all codecs from the offer without removing any

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.

Add RED (RFC 2198) codec definition to codeclib as a supplemental codec.
Modify codec_store_accept_one() to preserve supplemental codecs whose
clock rate matches the accepted primary codec. Skip supplemental codecs
in codec_store_is_full_answer() since they are optional in SDP answers.

In case of bitstream style codecs which still use an encoder which
operates on fixed frame sizes (e.g. G.726), passing the maximum allowed
frame/packet size to the packetizer is not enough. Instead it needs to
know separately how much data it is expected to return. Add another
argument to pass this information.
This also fixes the incorrect math to adjust the frame duration in case
of chunked output.

The format of a received audio frame can differ from the required format
for the audio player (Opus decoder supporting multiple sample rates).
Add a resampler in case resampling is needed.
