Two version of the origin replace exist from now on:
- `origin-replace` - replaces only the origin address
- `origin-replace-full` - replaces all the values,
so name, id, version and IP family with address.
Values for replacing are taken from the rtpengine instance,
so local values provided by the daemon.
Additionally: documentation updated accordingly.
Additionally: revert changes in pub-sub test.

Move the `call_subscribe_request_ng()` fully to a usage

Carry the origin IP and net family via flags
to the monologue, so can be reused later when creating SDP.
Always use given SDP session origin IP address and family
for the SDP being prepared, unless sdp origin replacement
is required via given flags (in this case just used
an advertised IP of rtpengine).
Additionally: fix unit tests for subscribe cases accordingly
to the policy.

- `stream_params` -> `call_media` in ` __media_init_from_flags()`

During the parsing of `rtpp_flags` use the
`call_ng_flags_flags()` directly instead of the
`bencode_list_add_str()`, hence reduce amount
of iterations required to parse generic flags.
Additionally:
`call_ng_flags_flags()` is made visible for usage
within external files.
`helper_arg` union has been moved to the header.
Change-Id: I34399a0d3940a1276feb1210e4421cbcdf656e9d
Is added by:
- explicit generic flag "directionl"; or
- if the "from-tag" flag is used
Introduce the `directional` flag for `sdp_ng_flags` struct.
In use by:
- `media_block_match1()`
Additionally:
add `IS_OP_DIRECTIONAL()` marco check.
Change-Id: Ifd56ea2ad8277d7dec136def1c028c5e2b680ff1
For the sake of proper processing for From/To tags,
we need to know which message type originated interaction
with the rtpengine (from behalf of kamailo module).
This can be of two types:
- request
- reply
This can also be re-used later, if there is a need
to detect whether that was a request or reply.
P.S.: opmode and message type shouldn't be confused,
it's not the same, since SDP offer can come in the request
as well as in the reply message (late offer/answer).
So the opmode reflects what exactly is being done in terms of
rtpengine operations, meanwhile the message type shows, which
message type originated this processing.
Change-Id: I8336175d3cfcf521418ac18b71cb4a6d5730705d
Synchronize the `enum call_opmode` with the
kamailio module list of operation modes, as well
as with the `enum ng_command`.
This allows to operate based on `call_opmode`
in a more specific way, for example for a proper
setting of From/To tags based on directional flag,
which in its turn is being set using `call_opmode`.
Additionally introduce a macro checker, which covers
all previously non-existent operation mode types
as OP_OTHER, for backwards compatibility in conditions.
Change-Id: Idf4b9d910b81ee24be51008996c3fd02d8336a38
Add support of rtpp_flags parsing for the daemon.
From now on, it's possible to parse option flags
on the daemon side instead of the kamailio module.
It's identical to what the module does, but the
difference is:
- module sends general call identification such as:
call-id, From/To tags, viabranch using bencode
- meanwhile all generic/non-generic option flags
are added to the `rtpp_flags` bencode member as str
- parsing of that is done as usually using the
`call_ng_main_flags()` / `call_ng_flags_flags()`
and additionally using new parser `parse_rtpp_flags()`
New file implementation and header introduced:
- control_ng_flags_parser.c
- control_ng_flags_parser.h
Otherwise no functional changes, and the parsing itself
remains working following the same algorithm.

In the file implementations follow the rules:
1. Firstly goes the correlated header file, then one empty row.
2. Secondly go system headers, so in angle-brackets, then one empty row.
3. Thirdly, go custom header files, so in double quotes,
then one empty row.
4. If there is "xt_RTPENGINE.h", it's mentioned next, but separately,
then one empty row.
5. If there are pre-processor definitions, they are added.
6. And eventually at least 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 the sequence,
and also possibly on some inline objects definitions, but if possible
to follow the rules, it's being done.

From now on the `call_subscription` concept gets
deprecated, and instead of it the `media_subscriptions`
concept gets applied.
Benefits of this change is:
- ability to subscribe one-to-multiple medias (different monologues)
- media level manipulations, without affecting whole SDP session
- no need to use medias offset, to detect proper subscription's media
- there is no need of particular medias order, they can be
subscribed to each other in any possible way
(even though RFC still requires to always have proper ordering)
Deprecated objects:
- `struct call_subscription`
- `GQueue subscriptions`
- `GQueue subscribers`
- `GHashTable * subscriptions_ht`
- `GHashTable * subscribers_ht`
Deprecated functionality:
- `__unsubscribe_one()`
- `__unsubscribe_all_offer_answer_subscribers()`
- `__unsubscribe_from_all()`
- `__subscribe_offer_answer_both_ways()`
- `__add_subscription()`
- `__unsubscribe_one_link()`
- `call_get_call_subscription()`
- `call_subscriptions_clear()`
- `call_subscriptions_free()`
Offtopic: additionally this commit adds helper func:
- `call_media_subscribed_to_monologue()`

In the `dialogue_unconfirm()` (previously `dialogue_unkernelize()`)

and correlated to them medias to unconfirm them.
This change is bound to the switch from monologue
subscriptions to media subscriptions.
Additionally: Refactor unkernelize/unconfirm in `call.c`
To provide a sense of the functions clearer,
the namings of the following function singatures

- `dialogue_unkernelize()` -> `dialogue_unconfirm()`
- `__monologue_unkernelize()` -> `__monologue_unconfirm()`

We have to move the list of attributes with following types
to the `call_media`'s `sdp_attributes` using `stream_params`:
ATTR_SSRC
ATTR_MSID
ATTR_OTHER
This is then required by the `insert_sdp_attributes()`
used by:
- `sdp_replace()` -> `replace_sdp_media_section()`
- `sdp_create()`
Additionally: move the `insert_sdp_attributes()`
to the usage of the `append_attr_to_gstring()`, which
gives SDP attrs manipulations control over attributes
being inserted into SDP. Previously not supported.
Additionally: `process_media_attributes()` takes new
argument `bool strip_attr_other`, in order to control
whether or not to strip `ATTR_OTHER/ATTR_SSRC/ATTR_MSID`.
For now there is only one user of it `replace_sdp_media_section()`,
but for later on, we can control this using this bool.
Additionally: `print_sdp_media_section()` takes new
argument `bool print_other_attrs`, in order to control
whether or not to strip `ATTR_OTHER/ATTR_SSRC/ATTR_MSID`.
This is required, because the sdp replacing/creating mechanism
needs a controllable way of adding them, users are:
- `janus_videoroom_join()`
`janus_videoroom_configure()` - always need them
- `call_publish_ng` - always needs them
- `call_subscribe_request_ng` - never needs them
(otherwise leads to a duplication of such attributes)
- `call_offer_answer_ng()` - requires them always
- `call_subscribe_request_ng()` - never needs them
(otherwise leads to a duplication of such attributes)

set it through call_get_or_create().

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.

Transcoding is flow-specific, so it doesn't make sense to have a flag

subscribers) have transcoding enabled.
