This triggers an initial "no carrier" indication if the sender is slow
to start PCM.

0x40000000 was already used by SHARED_FLAG_END_OF_CANDIDATES. Move
MEDIA_FLAG_REORDER_FORCED to unused slot 0x00800000 instead.

Grab source monologue and source media only once, and pass the object
down to the various functions, instead of doing the retrieval several
times in multiple places.

We know whether we're printing for monologues or for medias, so there's
no need to have a generic function signature.

(cherry picked from commit e0e4ba5b7c)
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 18579227a9)
Add a simple function that acts as an encryption callback to just update
the ext_seq (index) of the egress SSRC context. The kernel module
already does this, but the daemon only did it when SRTP was involved.
This now tracks egress packet indexes in all cases.

(cherry picked from commit 0da49000ba)
A call that gets created but then doesn't get initialised would have its
Redis DB left at zero. At destruction it would then try to switch to DB
zero. Fix this by using an appropriate initial value.

Use the call's memory arena to store strings (in particular the media
blob), and use intrusive allocation storage for the blob str itself.
Change-Id: I3a3d480869d61a2e66a24e88ad135bacca947072
This allows us to deallocate all held strings in one go without having
to iterate much.
Requires adjusting tests, Makefiles and dependencies.

Change old code to directly return `str` objects instead of pointers to
allocated ones. Largely a no-op change but makes some code easier and
eliminates some old kludges.
Change-Id: I2be19dd24bb7ff046d86cc32a3af235283e65dd0
Introduce global generic memory arena variable, instead of having just
a call-specific memory arena. This makes it possible to use memory arena
outside of call contexts. Define previous call-specific functions in
terms of the generic ones.

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.
Change-Id: I0f2a284955dbc045b51920174f1f4fbefcb93907
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)`
Change-Id: I75562eee60220885e233fa965bf22da92850a8f4
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

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.

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
