Mark those SDPs which trigger processing
of music-on-hold.
Is defined by the config option:
`moh-attr-name`. If not defined then
is not used.
Will be useful for cases when it's important
for remote components to detect ongoing hold.

Support inactive hold, because some
client implementations (such as Zoiper5)
are using `a=inactive` for their holds.
For us this means, either of this
puts the other side on hold:
- `sendonly: !MEDIA_ISSET(media, SEND) && MEDIA_ISSET(media, RECV)`
- `inactive: !MEDIA_ISSET(media, SEND) && !MEDIA_ISSET(media, RECV)`

Make the macro return the appropriate pointer type, and make sure the
free function takes an argument of the same type. This also eliminates
some boilerplate type-casting code.

If with the sendonly SDP offer capable of MoH,
there is a flag `repeat-duration` coming at the
same time, then warn a user of rtpengine
that the configuration option is used with MoH
and it's not possible to take the flag's value.
Change-Id: Iacf3ddd85749da3ad98758e386952ab7cec5ca8d
Introduce `moh-max-repeats` configuration option,
which controls the `rtpe_config.moh_max_repeats`
used when initializing media player options
for the music-on-hold functionality.
By default is always set to 999,
if not defined otherwise.
Change-Id: I247dc532a6871934e44f9c4002313363356937fb
Make `moh-max-duration` available for both
music-on-hold functionality as well as
for the media player.
For that to work, do the following:
- keep `moh-max-duration` config option only for MoH,
if not set (so 0) by default is 1800000ms (half an hour)
- for the play media functionality introduce flag option
`repeat-duration`, by default is disabled
Policy changes:
- duration counter can be used in common with repeats
counter, but then takes a precedence over it.
Hence if first a duration is underflown, then EOF triggered.
Otherwise if the duration counter is still positive, but
repeats are negative, then do EOF based on repeats.
- the repeats counter will always count down during each
iteration, even when used together with the duration counter
For MoH to survive, the repeats counter is simple set to 999
to let the duration counter always win over repeats one
- MoH cannot take duration disabled, since otherwise
would make no sense for it. Hence always takes internally
defined value 1800000ms (half an hour) if not defined
by the configuration option
Backwards compatibility:
- is kept in regards of repeats counter
- is kept in regards of the play media functionality

Add a couple of tests for the following cases:
- use both zero-connection + mode sendrecv flags
at the same time
- answerer puts on hold (instead of offerer)
Change-Id: I5f849aa6b79a2e7e31512fbad9d2b82a6f5b0027
Sendrecv mode flag controls whether the sendrecv
state is forced to sendrecv, instead of the default
one sendonly, in the SDP body going towards recipient
(the one who will receive the MoH media).
Is declared as: moh=[mode=sendrecv]
Can be useful for corner cases, where the remote side
wants to see sendrecv state for whatever reason,
when getting MoH media and hence also remain in sendrecv
state in regards of the MoH originator.
Must be advertised once during the session origination,
nd then will affect the SDP body as soon as SDP sendonly
body is received (from the behalf of one, who advertised MoH
capabilities).
Backwards compatibility: doesn't affect non-MoH calls.
And doesn't affect offer/answer exchanges within MoH calls,
which do not put the remote side on hold.
Additionally: introduce a common function for the MoH flags
handling: `call_ml_moh_handle_flags()`, which does all
the required iterations/checks for the whole bunch of flags
at once.
Additionally: previously existing MoH tests adopted.
Additionally: new test introduced to check the SDP content,
when using mode sendrecv flag.
Remark: this flag is not mutually exclusive with
the zero-connection MoH flag.
Change-Id: I5bf6699f6890d8b927107cc143a18116efe45087
Zero-connection flag controls whether the connection
address offered in the SDP body going towards recipient
(the one who will receive the MoH media), is set
to all zeroes.
Is declared as: moh=[connection=zero]
Can be useful for older client implementations,
who want to see zeroed media when receiving sendonly
and getting put on hold.
Must be advertised once during the session origination,
and then will affect the SDP body as soon as SDP sendonly
body is received (from the behalf of one, who advertised MoH
capabilities).
SDP body recovers to the real IP addresses being inserted
into recipient's SDP, as soon as the media gets unheld.
Backwards compatibility: doesn't affect non-MoH calls.
And doesn't affect offer/answer exchanges within MoH calls,
which do not put the remote side on hold.
Additionally: previously existing MoH test adopted.
Additionally: new test introduced to check the SDP content,
when using zero-connection flag.

Move conditioning and handling of MoH
into a separate helper to make code a bit
more laconic.
No functional changes.
Change-Id: I89502bbdfe75e0b96c42ac0bde405e3ed04403fa
Add duration limit for the moh functionality.
This is required due to a possibility to get
monologues and hence packet streams stuck
forever and sending audio to recipients
which already don't exist.
A configuration option that controls that:
`moh-max-duration` - gets a value in milliseconds.
By default is set to 1800000 (half an hour).
Change-Id: Id50a0a10ce5b52b3876a3122fb16a71accec90ff
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()`
Change-Id: I0db13e1f851e6c59d29ffb5adf5cb8d01bfd5bcc
`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()`

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.

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.
Change-Id: I6d1ac3bb5cb27443c31f0f3b9ce8f47c416cd3ce
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.
