Start using the media subscriptions model
(based on newly introduced `media_subscription` objects)
in scope of:
- `ng_stats_monologue()`
- `ng_call_stats()`

Previous implementation assumes that we use the `call_subscription`
objects in:
- `call_offer_answer_ng()`
- `call_update_lookup_udp()`
- `call_request_lookup_tcp()`
when appealing to the `call_get_mono_dialogue()`, in order to
get the `call_subscription` objects, in order to then pass it
for usage in the `monologue_offer_answer()`, where the most important
again is to use monologue references stored inside
the given `call_subscription` objects.
Instead of using the `call_subscription`, just use `call_monologue`
objects as a base data objects for this work,
which will allow us in the coming commits to deprecate
the `call_subscriptions` based model and
get to the subscription model based on medias.

To be able to use this feature from controlling agents which don't
directly support the new dictionary keys, add an alternative syntax via
the `flags` list. This is in line with all other similar dictionary keys
(e.g. `codec-` etc)

Similar to the other list building helper functions, add one that builds
a key/value table. The benefit is that this can then be used as a
callback in a different context.

These functions iterate over lists, building hash tables or queues
respectively. Eliminate code duplication.

Operating on an empty queue is essentially a no-op, so there's no point
in doing an extra check first to see if the queue is empty. Remove this
extra check for the CMD_ADD case.

Use an indexed array to generically support all possible media types
instead of hard-coding a few possible types. This makes lookup faster
and is also future-proof.
Add helper functions to allocate and lookup the appropriate object.

Add second callback function to be able to handle lists that not just
contain strings, but also arbitrary other elements.
Rename the old call_ng_flags_list to call_ng_flags_str_list to reflect
this.
Unused at this point.

Transcoding is flow-specific, so it doesn't make sense to have a flag
for it in a call_media section. Instead we use the transcoding flag set
on the call_subscription objects (on subscribers), and set/unset a flag
on the monologue struct, depending on whether any media flows (going to
subscribers) have transcoding enabled.

Instead of just return the monologues involved in an offer/answer,
return the respective subscription objects that have the monologues
pointing to each other. This makes it possible to set flags within these
objects.

Make it possible to set output-destination immediately when starting the
reording, not only afterwards.

For efficiency reasons `substitute` kind of SDP manipulations
commands have been moved to the `GHashTable` instead of the `GQueue`.

Add a flag to inhibit kernel mode while DTMF injection is active. Tie in
DTMF playback trigger function: Remove stream from kernel, set inhibit
flag, play DTMF, then unset inhibit flag when all events have been
injected.

When the `discard-recording` flag is given in one of the commands to
rtpengine (e.g. in the `delete` command), the metafile is renamed to a
.DISCARD suffix and then deleted.
The recording daemon then, seeing the .DISCARD suffix, proceeds to
immediately close all recordings, delete the files if any, and delete
the entries from the DB.

Rename the original call_delete_branch() to call_delete_branch_by_id()
and provide a new call_delete_branch() which takes a reference to a call
object instead of a call ID.

Move trickle ICE handling out of __media_init_from_flags and into a
higher-level function. This obsoletes the special magic return value to
indicate a trickle ICE failure.
All methods accepting trickle ICE updates must now explicitly call the
trickle ICE update function.
The requirement to have a full dialogue for trickle ICE updates is
removed as trickle ICE only affects one side.
Change-Id: I0850e1858876ca7bcdd39b7144b53b5a4afed53e
Moving code for handling (queuing, dequeuing) trickle ICE fragments into
ice.c, where it makes no sense. No functional changes.

This is slightly more performant as it does the retrieval and removal
with just one lookup instead of two.

Using a pointer array instead of a linked lists allows us to directly
reference a media section by index number, without having to spool into
the linked list.
No functional changes.

Require all callers of media_block_match() and play_media_select_party()
ot provide their own "flags" and do the cleanup of them afterwards.

It substitutes a specified `a=` line taken from the concerned
media attributes list. If such line has been not found,
the attributes list remains untouched.
It subsitutes one attribute at a time, so one attribute into
another attribute.

Track audio writes in the mix buffer to set the `active` flag to true
whenever a write occurs, which makes it possible to create the buffer in
an inactivate state and implicitly set it active on demand.
Handle the mix buffer not returning any data in the RTP sending logic
(which is what happens for an inactive buffer) by simply not sending any
packets.

Similar to the existing media_player, but instead of simply producing
its own standalone output media stream, the audio_player takes over the
entire media stream flowing to the receiver, including media forwarded
from the opposite side of the call, as well as media produced by the
media_player.

In order to improve the efficieny of the code (make lookups
faster) use GQueues for CMD_ADD manipulations and
GHashTable for CMD_REM manipulations.
This gives the following benefits:
- faster lookup (check), if any SDP command is to be applied
(no need to iterate through all values of commands, as it used to be)
- keep a sequence for CMD_ADD values given by option flag(s)
In order to keep the code more lightweight and clear,
add a separate struct ptr to queues and hash tables into
the call_interfaces header.
