During the `monologues_intact` stage of the `call_get_monologue_new()`
use media subscription in order to:
- update `os` ml, if still not set before
- update subscription ml's tag with totag, if not set before
After the first possible subscription's `offer/answer` ml
has been found and all work done, break cycling expecting
that this is one-to-one (so offer/answer) model, where only
medias of two monologues are involved.

Rework the logic of fromtag monologue detection in the
`call_get_dialogue()`.
Fristly, try to match using given from tag (if there is one).
Secondly, try to match using given viabranch.
Thirdly, try to use top-most subscription of the top-most
media related to the totag monologue (newer behavior).
Fourthly, if still not found just create a brand-new one.
This change relates to the fact, that we stop using call monologue
subscriptions model and switch to the media based one.

Due to introduction of media subscriptions model.
Rely on subscription monologue's empty tag,
while trying to detect, whether or not to destroy given monologue
but with a clause that:
- this ml is subscribed to medias of other signle ml
It's important to keep this check because
if the `delete` is done with from-tag and to-tag,
just right away after an `offer` without the to-tag
and without use of via-branch, then the call's data
can potentially remain dangling without being deleted completely.
So looking up the offer side of the call through the from-tag
and then checking, if the call has not been answered
(answer side has an empty to-tag), gives a clue whether
to delete an entire call.
Additionally, introduce a helper function:
- `ml_medias_subscribed_to_single_ml()`
which checks, whether this monologue medias are subscribed
to a single other monologue medias.

From now on, the newer media subscriptions based concept has been
introduced, which means the call monologue is able to have:
- medias, which have non-even amount of subscribers and subscriptions
- medias of different monologues in the media's subscriptions list
- medias of different monologues in the media's subscribers list
Further, improve the `call_get_dialogue()` accordingly so,
that a detection, whether or not a from-monologue has already seen
before given to-monologue, will be based on from-monologue's media subscriptions.
Absent to-monologue medias in from-monologue subscriptions list means —
to-monologue has been never seen before, and we have to update tags accordingly
as well as subscribe matched medias of to/from-monologue to each other.

Moving from call subscriptions to media subscriptions.
Add a possibility to run `media_stop()` and `__monologue_stop()`
for all related to this monologue media subscribers.
This is an improvement, which gives the following benefits:
- all subscribers are handled inside of the func, less code out of it
- the function gets in sync with new media subscriptions concept

Use media subscriptions model in the `kill_calls_timer()`
to find subscribers and related monologues in order
the to update the `xmlrpc_helper` data.

In the `dialogue_unconfirm()` (previously `dialogue_unkernelize()`)
use media subscriptions to find subscribers/subscriptions
and correlated to them medias to unconfirm them.
This change is bound to the switch from monologue
subscriptions to media subscriptions.
Additionally: Refactor unkernelize/unconfirm in `call.c`
To provide a sense of the functions clearer,
the namings of the following function singatures
have been changed:
- `dialogue_unkernelize()` -> `dialogue_unconfirm()`
- `__monologue_unkernelize()` -> `__monologue_unconfirm()`

Report to whom a `call_monologue` is subscribed and
who is subscribed to it using media level subscriptions
instead of using monologues one.

Add handling of SDP session level attributes for:
- `monologue_subscribe_request()`
- `monologue_subscribe_answer()`
This will be used by `janus.c` related functionality.

Move `a=extmap:` attribute to the `call_media`'s
`sdp_attributes` using `stream_params`.
Required by the `insert_sdp_attributes()` used in `sdp_create()`.
Additionally revert `extmap` unit test checks in the
`testVideoroomWebRTCVideo`.
Change-Id: If63e4e8733ea0899f34fae1f1d38997e9e2c081c
Move `a=ssrc-group:` attribute to the `call_media`'s
`sdp_attributes` using `stream_params`.
Required by the `insert_sdp_attributes()` used in `sdp_create()`.
Change-Id: I67025dc83dd8e5e46422b6dc1bc54aa9c838dfea
We have to move the list of attributes with following types
to the `call_media`'s `sdp_attributes` using `stream_params`:
ATTR_SSRC
ATTR_MSID
ATTR_OTHER
This is then required by the `insert_sdp_attributes()`
used by:
- `sdp_replace()` -> `replace_sdp_media_section()`
- `sdp_create()`
Additionally: move the `insert_sdp_attributes()`
to the usage of the `append_attr_to_gstring()`, which
gives SDP attrs manipulations control over attributes
being inserted into SDP. Previously not supported.
Additionally: `process_media_attributes()` takes new
argument `bool strip_attr_other`, in order to control
whether or not to strip `ATTR_OTHER/ATTR_SSRC/ATTR_MSID`.
For now there is only one user of it `replace_sdp_media_section()`,
but for later on, we can control this using this bool.
Additionally: `print_sdp_media_section()` takes new
argument `bool print_other_attrs`, in order to control
whether or not to strip `ATTR_OTHER/ATTR_SSRC/ATTR_MSID`.
This is required, because the sdp replacing/creating mechanism
needs a controllable way of adding them, users are:
- `janus_videoroom_join()`
`janus_videoroom_configure()` - always need them
- `call_publish_ng` - always needs them
- `call_subscribe_request_ng` - never needs them
(otherwise leads to a duplication of such attributes)
- `call_offer_answer_ng()` - requires them always
- `call_subscribe_request_ng()` - never needs them
(otherwise leads to a duplication of such attributes)

The index j we get is not the position in the output array/list, but
rather the index into the source array. Simply append each new element
to the array in order.
Also make sure we don't skip over empty elements in the array when
building the JSON list, so that the order is preserved.

For the use case with a separate base chain, we want to preempt other
firewall rules by default and insert our immediate jump rule at the

behaviour.
