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).

Instead of keeping one global hash/list of all received ICE fragments,
indexed by string call ID and from-tag, move the hash/list of ICE
fragments into the call object, now indxed only by the from-tag.
This requires a call object to exist before an ICE fragment can be
stored. Change the order of operations to always create a call object
first, then parse the SDP, then check for ICE fragment processing. The
determining factor now is only whether the monologue exists.
Duplicate the raw SDP into the call's memory arena instead of onto the
heap.
ICE fragments now don't need to store the pre-parsed SDP any more, and
the trickle ICE handling code is guaranteed to always have the fully
parsed SDP information.
Strings for fragment indexes can now be allocated from the call's memory
arena.
Obsolete the extra thread used to delete old ICE fragments. This is now
done in-line with regular call timeout processing.

Move the SDP offer/answer model to the sdp_create
approach instead of using the sdp_replace one.
This assumes the SDP body including session level
attributes (s=, o=, t= etc.), as well as the media
attributes, are formatted using currently given
session context.
In other words, rtpengine collects all possible
information during all of the offer/answer exchanges
within the dialog, which in its turn affects each
monologue's context, from which each new SDP message
will be built up.
This approach replaces the older one, which instead
used to go through the currenty processed SDP and
just replace those attributes, that rtpengine
is required to affect, leaving the rest untouched.
Additionally: all of the existing offer/asnwer model
tests were fixed to comply with the currect change.
Most of it is just an offset of attributes, which are
stored a bit higher/lower within the same media or global
SDP session.
Also a good part of unit test fixes targets a move of
`c=` line from the session level to the media one (so
each media has from now on its own `c=` attribute). This
does discontinue a support for session level connection
information.

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.

... 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).

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.

Synchronize the `enum call_opmode` with the

as with the `enum ng_command`.
This allows to operate based on `call_opmode`

setting of From/To tags based on directional flag,
which in its turn is being set using `call_opmode`.
Additionally introduce a macro checker, which covers
all previously non-existent operation mode types
as OP_OTHER, for backwards compatibility in conditions.

Add support of rtpp_flags parsing for the daemon.
From now on, it's possible to parse option flags
on the daemon side instead of the kamailio module.
It's identical to what the module does, but the
difference is:
- module sends general call identification such as:
call-id, From/To tags, viabranch using bencode
- meanwhile all generic/non-generic option flags
are added to the `rtpp_flags` bencode member as str
- parsing of that is done as usually using the
`call_ng_main_flags()` / `call_ng_flags_flags()`
and additionally using new parser `parse_rtpp_flags()`
New file implementation and header introduced:
- control_ng_flags_parser.c
- control_ng_flags_parser.h
Otherwise no functional changes, and the parsing itself
remains working following the same algorithm.
