If the receiver of a previously passthrough T.30 stream gets switched to
a generated PCM stream from a T.38 gateway, continue the sequencing of
the previous SSRC. Technically this is not necessary as the generated
PCM stream gets a new SSRC, but at least Asterisk seems to ignore this
and expect sequencing to continue, and will ignore PCM if the sequence
jump is too large.

(cherry picked from commit cf9a1fd396)
Use the call's memory arena to store strings (in particular the media
blob), and use intrusive allocation storage for the blob str itself.

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

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.

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.

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).

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.
Change-Id: I278f7bc5a6663e9232e812d10f6902616c67c497
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()`
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()`.

Turn repeat count into an int. No need for a long long.
Store start_pos in media_player.
Set start_pos and repeat count at the relevant code points once, instead
of passing it into multiple functions.
Take the opportunity to turn these shared options into a struct.

In the header files follow the rules:
1. Firstly goes ifndef/define construction, then one empty row.
2. Secondly go system headers, so in angle-brackets, then one empty row.
3. If there are important pre-processor definitions, which affect
the following custom file headers, they are added next, then one empty row.
4. Thirdly custom header files, so in double quotes,
then at least one empty row.
5. If there is "xt_RTPENGINE.h", it's mentioned next, but separately,
then one empty row.
6. Then pre-processor definitions, and one empty row before the code.
In some situations it's allowed to step aside from the rules,
when inclusions are dependent on each other, so on specific sequence,
and also possibly on some inline objects definitions.
But, if possible to follow the rules, it should be done.
