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.

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.

Convert existing sdp manipulation helpers
to work with arrays directly, independently from
which array is actually given.
Moreover, don't use the `G_N_ELEMENTS()`,
since we already have the `__MT_MAX`
as the size of the array, so we can directly use
that instead of relying on the G_N_ELEMENTS macro
(for array size checks).

Add `call_ng_process_flags()` based parsing
as for other opmodes, like offer and answer.
This keeps the backwards compatibility with
the older "flags" parsing approach on the
module side, as well as adds the possibility
to parse rtpp-flags on the daemon side.
As an advantage, there is no need to use
specific local parsing for things like
to/from tags, call-id, delete-delay etc.
Additionally:
- this commit introduces flags-flags parsing
for the "fatal" flag.
However, as before is only taken into account
by the `call_delete_ng()` processing,
so no functional change.
- this commit introduces main-flags parsing
for the "delete-delay" flag, which is also
only taken into account by the `call_delete_ng()`
processing, so no functional change.
- this commit adds To-tag options flag prasing
into the `call_ng_flags_flags()` function,
and is used by `call_delete_ng()` specificially,
for cases when more specific identification of
monologues to be deleted is used.

Support session level group attribute
for the sdp_create approach.
Additionally: fix the `testVideoroomWebRTCVideo` test,
because as it turned out it used to lose the `a=group:`
attribute before.

Added support of the CT (conference total) bandwidth
attribute for the SDP session level. See RFC8866.
Will be required later for the SDP formatting in `sdp_create()`.

... so that the desired wav channel can be controlled when producing a
mixed audio file
When a mixed wav file is created, the channels in the wav container are
currently allocated in the same order as each SSRC is received, meaning
it is impossible to know which channels have been allocated to the offer
or answer side of the call. Furthermore if there is a reinvite or media
file played, these are also allocated in the order that SSRC is received
- so an "answer" could end up sharing a channel with an "offer" with no
way of knowing this.
This patch allows you to specify how many channel slots should be
allocated within the mixer, and allows you to then specify which slot is
assigned to each media in the call (this will usually be 2 slots in
total, slot 1 for answer, slot 2 for offer or vice versa).

Two version of the origin replace exist from now on:
- `origin-replace` - replaces only the origin address
- `origin-replace-full` - replaces all the values,
so name, id, version and IP family with address.
Values for replacing are taken from the rtpengine instance,
so local values provided by the daemon.
Additionally: documentation updated accordingly.
Additionally: revert changes in pub-sub test.

Instead of using separate data members to
bring data with the `call_monologue` structure,
just use the whole `sdp_origin` object type (structure)
as a pointer and keep it aling with real SDP origin
of according monologue's side.
Refactor the code accordingly for `sdp_create()`
users (firstly only here).
Additionally introduce functions to alloc/de-alloc
`sdp_orig` object:
- `sdp_orig_dup()` returns a pointer to copied object
- `sdp_orig_free()` deallocates it

Always ensure to set the actual sdp session timing

Otherwise just use default value "0 0".
A new dedicated func `sdp_out_add_timing()` introduced
for that.

Always ensure to set the actual sdp session level

A new dedicated func `sdp_out_add_bandwidth()` introduced

Additionally: explicitely set b=RR/b=RS to -1 when creating
a brand new monologue (e.g. for subscriber requests case)
so it's not considered as 0 inadvertently.

In order to be able to set `sdp_origin` related things

Direction parsing.

Codec related flags parsing.
A bencode list for codec related flags keeping (while

During the parsing of `rtpp_flags` use the
`call_ng_flags_flags()` directly instead of the
`bencode_list_add_str()`, hence reduce amount
of iterations required to parse generic flags.
Additionally:
`call_ng_flags_flags()` is made visible for usage
within external files.
`helper_arg` union has been moved to the header.

Additionally:
add `IS_OP_DIRECTIONAL()` marco check.

For the sake of proper processing for From/To tags,
we need to know which message type originated interaction
with the rtpengine (from behalf of kamailo module).
This can be of two types:
- request
- reply
This can also be re-used later, if there is a need
to detect whether that was a request or reply.
P.S.: opmode and message type shouldn't be confused,
it's not the same, since SDP offer can come in the request
as well as in the reply message (late offer/answer).
So the opmode reflects what exactly is being done in terms of
rtpengine operations, meanwhile the message type shows, which
message type originated this processing.

Handle the `output-destination` flag in the same way as the `metadata`
flag, eliminating the need to do it explicitly everywhere it's relevant.
Add a few alternative spellings of `output-destination`.
Rename the member from flags to `recording_file` to make it more clear
what it is.
Add save/restore capabilities of that field to the Redis code.
Unify printing of monologue LABEL into the same function that handles
the metadata.
Update documentation to better explain this option, and use the new
clearer name.
