The `answer` processing empties out the list of codecs and leaves only
those that were accepted in the answer. Side effect of this is that if
another answer with a different list of codecs comes through, them the
codec-accept function is missing the original list of offered codecs and
can yield an incorrect result.
Fix this by storing a copy of the offered codecs at the end of the
`offer` processing, and then restore this list at the beginning of each
`answer` message.

In many transcoding scenarios resampling is not actually required. We
can shortcut the operation by just returning the original frame, instead
of a cloned and newly allocated one. We just need to distinguish between
the cases to determine whether the frame returned by resample_frame()
needs to be freed.

In some cases, in particular when multiple input codecs are transcoding
to the same output codec (e.g. audio + DTMF -> audio), it's possible
that one of the input decoders produces frames in a format different
from the one expected by the encoder. Add an encoder-side resampler to
compensate for that.

Some compilers seem to think that there is some uninitialised usage
here. Work around this.

If recording-method is pcap, then proc is zero-initialized, so
meta_filepath is empty. This shows many logs such as:
[core] Failed to open recording metadata file '(null)' for writing: Bad address
Prevent them by returning earlier.

Use an object with local storage for sdp_address instead of just setting
a pointer. This makes it possible to put a different address.

The opmode is already determined uniquely when processing the NG
command. There is no need to explicitly set it again elsewhere. Simply
carry along the originally determined opmode.

These macros were used for development only and are not needed any more.
Their names collide with an upstream patch, making compilation fail on
kernels >= 6.12. Just remove these wrapper macros altogether.

Allow to-tag updates in answers only until a non-provisional response is
received. Add a flag to optionally suppress this feature.

If we receive an answer from a to-tag that hasn't previously seen and no
corresponding monologue exists (created from a previous offer),
previously we would treat this is a separate and new call branch, create
a brand new monologue and dissociate the previous one. This may lead to
unexpected results as this new monologue has been created without the
same initialisation as was done for the original one, and so may be left
with incorrect or incomplete data (e.g. SRTP keys, codec information,
interface bindings, etc).
Improve this by treating an unexpected and unseen to-tag as an alias to
the already existing to-tag. Going forward both tags can be used
interchangeably to refer to the same monologue.
Add a flag to suppress this new behaviour, in case some situation is
made worse by it.

When re-establishing connection to redis via hostname,
at a point of time upon new re-resolve hasn't been done yet,
use a hostname for logging of failing attempts to connect,
so that it doesn't confuse users with the older IP.
For the backwards compatibility, this will still log an IP
for those setups using the IP address and not a hostname.

Refactor media level manipulations, no funcitonal change.

In order to be able to control, which media types
one wants to have in the call session,
add support of the "sdp-media-remove" flag.
Syntax:
"sdp-media-remove" : ["<media-type>", "<media-type>", ...]
Additionally, add according unit tests.

During the monologues lookup in
`call_get_dialogue()`,
instead of relying on the very first available
other side subscription, when doing a lookup
of this side, try to look into all of them
to find available media with existing subs.

While handling offer/answer exchanges, do:
- index based lookup for sender's side (both offers and answers)
- index based lookup for receiver's side, but for offer only
- subscription based lookup for receiver's side, but for answer
Additionally: fix "media playback after delete" test,
because each new offer/answer exchange towards new branch,
means to have new via-branch value.

Don't unsubscribe offer from its existing
subscriptions, because it may have multiple
branched receiver's monologues, and hence medias.

When calling `__subscribe_medias_both_ways()`,
add sender to receiver, and not the other way.
This is just for simplicity of code reading
(so kinda: from -> to).
