To not come across the sink's mutation (e.g. `endpoint.address.family`)
just lock way earlier, before to start processing and
translating endpoint to the kernel related structs.
Otherwise the other signaling path may mutate something
which will make the sink unactual and provide
to the `__re_address_translate_ep()` NULLed or garbage structs.

16de9688d6 resets the `socket.family` to NULL,
that makes the direct appeal to the corresponding
object unsafe.
E.g. `ps->selected_sfd->socket.family->name` when
filling the streams.
Add a simply guard and log `none` in case
the ip family is NULL.

(cherry picked from commit 5937851296)
ICE drops packets early in media_demux_protocols() (via
ice_peer_address_known()), which means in media_packet_address_check()
we can immediately set any socket as confirmed that has received
anything.
Take receiving socket into account to determine whether the endpoint is
a match.
Disable endpoint learning with ICE. ICE is in charge of determining
endpoint address and local socket.
`media-handover` and `strict-source` handling remains in place. With
`media-handover` set, we allow changing endpoint and local socket based
on what is actually received, overriding the nomination from ICE.

``__assign_stream_fds`` cleared the stream fd queue without decrementing the ref count. This
prevented ``monologue_destroy`` from releasing the ports on unsubscribe.

In case of the reverse direction of a subscription, no stream handler will be found. Previously, the
decrypt struct was left zeroed, the kernel module rejected this with ``EINVAL`` and the daemon logged:
```
[core] Failed to push relay stream to kernel: Invalid argument
```
This patch sets ``REC_NULL``/``REH_NULL`` and marks the target as non-forwarding, matching what is
expected by ``validate_srtp``.

Currently the function has two cycles (while-outer-cycle and
for-inner-cycle).
The inner one operates on the given `pp` pointer and can potentially
mutate it (the pointer isn't const), hence the outer cycle will
continue with a mutated pointer.
Instead just use a local scope pointer to manipulate linked list's
data.
P.S.: the `pp` pointer isn't a double pointer, so unlikely was
expected (even by design) to be modified (e.g. its address or what
it actually points to).

Previous approach based on the strhash used
to support an upper case variant of "cli" command.
Just preserve it.
Current NG_COMMANDS based macro generation, uses
only lower cases based on the command name from

one exception for the "CLI".

For the following arrays:
- `ng_command_strings`
- `ng_command_strings_esc`
- `ng_command_strings_short`
Because there are still external users of them,
which should be reworked in the future to use the
`ng_command_defs` instead.
Change-Id: I4086513e295b00cc23ee035b004e896a83294bf9
With the newly introduced `ng_command_find()` lookup func.
Add the local `ng_command_def` and maintain via it.
Check whether:
- the handler has been defined
- the handler gets properly selected
- the command is defined (known)
Accordingly update the opmode of the command context.
By default define as `OP_OTHER` always.
For the case when no handler has been defined, introduce
the error reply "No handler found".
Accordingly trigger selected handler after
the command was found.
The main payoff here is that the command processing
flow becomes quite transparent and easy to maintain:
- parse command string
- lookup command definition
- set opmode from table
- call uniform handler
- shared error/success reply handling for all commands
Deprecate strhash based `__csh_lookup()`/`CSH_LOOKUP()`.
Accordingly adap the daemons's and tests Makefile,
remove the strhash objects with the normal control_ng one.
Additionally:
introduce the special `resultstr = "pong"` for the
ping command case, because all other commands have "ok".
Change-Id: Ifff7d7f61ae4d25fd220460f4485d794c9a7cbd5
Instead of the previous approach using the strhash,
introduce if-based lookup from `NG_COMMANDS`.
The usage of strhash is deprecated because it:
- forses string literals in switch cases, hence gives
no possibility to use variables
- makes then shortcuts using macro not possible to be used
- it makes the part with the command find and
actual commands definition duplicate, because
one has to maintain both of them when adding/removing commands
- switch is redundant and feels heavy, meanwhile the same
thing can be generated using marco based on `NG_COMMANDS`
introduced before, which are the main source of the truth
Newer approach:
- avoid usage of for/while cycles (because CPU consuming)
- sorts the lookup based on the cmd name (string) length,
what makes the command find efficient, because exlcludes
unnecessary comparisons
- uses the `memcmp()` at the very last
- for example, for the "offer" command it may run the `memcmp()`
only two times, because there are only two commands with
the length 5 our of supported 35 commands in list now
Additionally:
include `string.h` for `memcmp()` operations.
Change-Id: Iae70de87b88cd444ae162ba2b7c6aa7690731ee3
Introduce a common NG commands table `ng_command_defs`
for all type of things: OP enum, name, escaped name,
short name and most important the handler.
This table operates on and returns a dedicated struct `ng_command_def`,
which has all the information required on the command (like
all type of things mentioned above) and may have either
single-parameter or double-parameter signature (for cases with
the `addr` requiring commands such as the offer command).
Also add unified signatures for X and XA handlers,
they will be used later accordingly. Most of those use single-parameter,
and those exceptional use the second one.
Also add dummy plug-functions for ping and block/unblock silence media.
The ping one doesn't have any particular handler, but because a new
structure of NG commands wants to see a real declaration of the func
handler, just give it. For the block/unblock silence media, there aren't
even handling of commands in the control NG, they are just dummy OPs,
so fulfill the actual NG commands structure, and give them dummy funcs.

Keep enum `ng_opmode` generated from the command list,
and also keep `ng_command_strings[]`, `ng_command_strings_esc[]`

And add the wrapper func name into the array, to be able
to appeal to it later, when processing any coming NG command.
