Currently the helper accepts 0 length, but callers actually
can try to mutate it with `- 1` what means overflowing it.
e.g. `extmap_short_is_valid_data()` has a bitwise operation
including length `(id << 4) | (ext->len - 1)`

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).

When binding the port to a socket, init fd to -1
because 0 is actually a valid id for fd in the system,
this `struct socket_port_link spl = {0};` puts `.fd = 0`
and if socket binding fails, then `.fd == 0` which is
a totally valid fd.
Instead init it to -1 and then let `add_socket()` to
actually fill the structure's data properly,
if however that one fails to bind, then again return
`.fd = -1`.

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
the table, so not mess things more, just add
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.

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".

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.

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

When iterating through medias, check whether there is something in;
- `->streams.head`
- `->selected_sfd`

If transform setup can ever produce incomplete media,
this might crash while building the response.

When iterating through the monologues medias while
looking for the media sink, filter those, which aren't audio.
Such a media type will likely have no audio subscriber,

"There is no sink media capable of DTMF playback"

For-cycle expects the `sink_ml` for setting the `call_media`

is used, which is supposed to be used in the nested for-cycle.
Looks like a copy-paste typo. Major fix.

The loop is 1-based, but checks the outside
of bounds with `i <= 1`. If the length is 1 and
iterator is 1, this already fails.
Hence allow `i` to be 1, and also check it's not
beyound the media array length.

In case when adding blob id, we allocate a list of things, like:
`AVFormatContext`, `AVIO` buffer, `AVIOContext`,

On immediate failure this leaves the player
in a partially initialized state, just be explicit and
use the `media_player_coder_shutdown()` before to
return an error.

There seems to be a race condition with stream_fds/sockets being closed

checks.

This can desynchronize the hash key and the list key.
