Operating on an empty queue is essentially a no-op, so there's no point
in doing an extra check first to see if the queue is empty. Remove this
extra check for the CMD_ADD case.

Use an indexed array to generically support all possible media types
instead of hard-coding a few possible types. This makes lookup faster
and is also future-proof.
Add helper functions to allocate and lookup the appropriate object.

Media types must be given explicitly anyway, so we don't need to warn
when we encounter a different one, as it's entirely expected that we
won't operate on it.

For efficiency reasons `substitute` kind of SDP manipulations
commands have been moved to the `GHashTable` instead of the `GQueue`.

1) a=ice-options can be a session-level attribute. Use the correct
lookup function to check for both media-level and session-level
attributes.
2) The RTP endpoint address must be filled in before we do the trickle
ICE check, which uses 0.0.0.0:9 as determining factor.
3) Adapt a test case.

Using a pointer array instead of a linked lists allows us to directly
reference a media section by index number, without having to spool into
the linked list.
No functional changes.

Deprecate the `append_attr_to_gstring()` and combine the functionality
of it with the `append_attr_char_to_gstring()` to not have multiple
functions doing same thing.

Improve an efficiency of the code in terms of not checking anything
inside the function, if the `sdp_manipulation` flags are absent.

Do not use the `g_queue_is_empty()` to check the emptiness
of the `add_commands_*` GQueue. It's enough to check the pointer
and the first `->head` value.

Do not proceed to the `g_hash_table_lookup()` if the `attr_name`
is empty.
Additonally: improve slightly the same check for the CMD_SUBST.

It substitutes a specified `a=` line taken from the concerned
media attributes list. If such line has been not found,
the attributes list remains untouched.
It subsitutes one attribute at a time, so one attribute into
another attribute.

In order to improve the efficieny of the code (make lookups
faster) use GQueues for CMD_ADD manipulations and
GHashTable for CMD_REM manipulations.
This gives the following benefits:
- faster lookup (check), if any SDP command is to be applied
(no need to iterate through all values of commands, as it used to be)
- keep a sequence for CMD_ADD values given by option flag(s)
In order to keep the code more lightweight and clear,
add a separate struct ptr to queues and hash tables into
the call_interfaces header.
Change-Id: I7e45aca4062750c7b8959473edb410ed76cc04e7
New section of option flags has been introduced for SDP body
attributes manipulations.
Three levels of the SDP session are concerned:
- session level (global one)
- media level - audio
- media level - video
Three different actions are supported for now:
- add
- remove
The value of the command has a wildcard matching approach.
Other attributes apart `a=` can not be edited by this functionality.
So such headers as: `c=`, `s=`, `o=` cannot be touched.

(cherry picked from commit 3f06c18793)
Because of the repeating code snippets, which insert attributes
into the SDP chop->output GString, it's just better to introduce
a separate function for that.
This will give one additional advantage — there will be only one
place, where we can control (for example, depending on manipulation
rules) whether to print this attribute or not.

To better organizea code and not duplicate same functionality
in the future, it's better to handle an insertion of
the sdp_attribute object using a dedicated hanlder.
New handler:
attr_insert(struct sdp_attributes *attrs, struct sdp_attribute *attr)

Defined in RFC 8842. If a tls-id was previously given and a the new SDP
shows a different tls-id or none at all, we must restart DTLS.

In order to rewrite certain session-level SDP lines, we need to
reference a packet_stream which contains the correct information. But we
cannot simply rely on the first media section having a usable packet
stream, as the first media section could have been rejected. Iterate
media sections until we find a usable one.

Add a flag to force increasing the SDP version,
even if the SDP hasn't been changed.
And cover it with tests.
Flag name: 'force-increment-sdp-ver'
Additionally fix the name of the 'sdp-version' flag
in the 'rtpengine-ng-client' tool.

`flags` being NULL is not really a use case we have right now, but it
might be in the future. Make sure we don't crash.

Explicitly copy SDP up to the format list before printing it out. This

Setting the mux flag when rtcp-mux is given is fine, but we must still
provide an RTCP endpoint in case rtcp-mux ends up not being used, either
through an implicit RTCP endpoint or through a=rtcp.
