Introduced Music on Hold functionality:
- available only for the offer/answer model,
no other scenarios (publish, subscriber etc.)
are covered with it
- it gets advertised always at the beginning of
the call (original offer/answer exchange)
- can be added for both sides: offerer/answerer
- the one who advertises its MoH capabilities
with its SDP offer or answer, can later trigger
MoH using sendonly SDP and unhold remote
party using sendrecv SDP
- MoH covers only audio type of media sessions
- there is no specific selection of media sections
to be held, thus, if one audio media puts the
call on hold, the whole call is held
- list of parameters to be given when advertising
MoH capabilities: a sound source (file, blob or db source);
sendonly/sendrecv hold; zero-connection hold;
At least an audio file source must be given
- MoH cannot be mixed with the play media functionality,
the last one triggered will override previous one
- MoH must be unheld to stop the media being sent
towards a recipient, otherwise only a termination
of monologues will stop this packets stream

Move part of the `call_stop_media_ng` function body
to a separate function, to let it be available
for external function calls not particularly related
to play media NG function call.

Make most of implementations static to file
because used only locally:
- `media_player_play_file()`
- `media_player_play_blob()`
- `media_player_play_db()`
- `media_player_add_file()`
- `media_player_add_blob()`
- `media_player_add_db()`

`media_player_opts_t` is already used to pass
blob, file and db_id, hence makes no sense to pass
it one more time and reset parameters of
`media_player_opts_t` strcuture in actual implementation
to the same value again.
Change-Id: I97f4236b2c9565f12af44dc4aba85ebfc6d8cefa
Use `media_player_opts_t` object to pass file, blob and db_id
parameters via the following functions:
- `media_player_add_file()`
- `media_player_add_blob()`
- `media_player_add_db()`
Change-Id: I7612cd63d08bc00911ba68c0a5a81796d50d4722
Rename the following functions into
something more relevant so that it
doesn't correlate with the general
init function `media_player_init()`
which isn't call specific.
- `media_player_init_file()` > `media_player_add_file()`
- `media_player_init_blob()` > `media_player_add_blob()`
- `media_player_init_db()` > `media_player_add_db()`
Change-Id: I8efd877bfd4c7c300aec7efe6fbbb654f52de460
Pass file, blob and db_id via `media_player_opts_t`
structure members instead of using separate arguments
in `call_play_media_for_ml()`.

Move part of the `call_play_media_ng` function body

This function connects two call legs (two monologues), possibly from
different call IDs, into a single media flow. It pays attention to media
types and automatically engages transcoding if needed. The order of
media sections of different types can be differend between the call legs
that are being connected. Subsequent reinvites will produce SDPs with
the media sections in the correct order.

This function retrieves two calls from the global call hash while
avoiding deadlocks. This is needed because a "call_get(A) + call_get(B)"
would deadlock against a concurrent "call_get(B) + call_get(A)"
Unused at this point.

This function merges two distinct call objects into one. All contained
objects are moved, and the "source" call is then destroyed. Both call
IDs can then be used to refer to the same internal call objects. Call ID
aliases are kept in a list in the call object.
Change-Id: I8a37775fe0dc3e7ccfeb83e2a3b7d751601450fc
Create a dedicated helper function to remove a call from the global call
hash based on a particular call ID.
No-op as this just splits out the relevant code.

When media subscriptions are removed implicitly by
__subscribe_medias_both_ways(), we must update all RTP sink pointers of
all the streams of the affected medias. Otherwise these sinks will be
left unchanged despite the subscriptions having been removed.

To support scenarios with mismatched media sections between two sides of
a call that aren't based on explicit SDP manipulations, attempt to
lookup the peer media based on an existing subscription also for offers.
Add extra checks (media type, media ID, monologue pointer) to make sure
that the obtained media object is actually the correct one.
Use a fallback on the existing index-based lookup in case no matching
media can be found.
As a side effect, the numbering and ordering of media objects created
during offer/answer is now reversed as the function is called in a
different order. Adapt tests as needed.

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.

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.

There is enough overlap between the two enums that it doesn't make sense

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.
