When accessing the array members via the pointer they
are still read-only, but the entries themselves are mutable.
So just make the elements constant pointers.
Also comply with the indentation style, and use tabs, not spaces.

In case the allocation of pcre for streams regex
fails, but not for the info, we never free
the latter one, because on returning an error,
just calling `die()`, hence no de-allocation
procedures are fulfilled.

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`
- `->socket.local.address.family`
before to blidnly appeal to it.
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,
and most probably will return with:
"There is no sink media capable of DTMF playback"

For-cycle expects the `sink_ml` for setting the `call_media`
at the upper level of the cycle, but instead the `monologue`
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.

No functional changes. Refactors are:
- use `UINT_MAX` instead of `-1`
- add definition `KERNEL_IDX_NONE = UINT_MAX`
- use `KERNEL_IDX_NONE` to se none value
- use `KERNEL_IDX_NONE` to check the none in conditions

In case when adding blob id, we allocate a list of things, like:
`AVFormatContext`, `AVIO` buffer, `AVIOContext`,
and we manage to copy it before returning an error.
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
while ICE checks are running at the same time, referencing the same
stream_fds. Solve this by holding a reference to the stream_fd in the
ICE pair object.
Additionally, add a check for a possibly closed socket when running
checks.

The `name` is caller-owned, while the cache itself
also keeps a separate key object
in the `media_player_media_files_names`.
This can desynchronize the hash key and the list key.
Hence prefer using the owned key instead.

The only caller of `media_player_get_cache_times()`
does comparisons based on microseconds, but the called
function to calculate `mtime` and `atime` does this in seconds.
Hence the result is used incorrectly, because it compares
that value against `rtpe_now - rtpe_config.db_expire_us`,
which is again in microseconds.

The `OP_...` enum is meant to only represent commands list.
Then make the list from the NG commands macro
the actual source of truth for the enum count.
This eliminates human mistakes, when introducing a new command,
because no more need to update enum manually.
Additionally:
- move the command list macro to the header
- existing extern declarations remain untouched
- `OP_OTHER` remains sentinel
- eventually replace the manual enum with macro based one

Instead of keeping separate arrays (essentially it's
a duplication) for command strings, escaped strings
or short version of commands, just create one single
macro pattern, which keeps these as an array.
And then using designated array initializers,
use the marco pattern to generate accordingly
an array of the required type (usual strings,
those escaped or the short version of them).
This prevents the human mistakes, or at least
makes them less possible in case of new command
introduction.

If someone wants to stop the media for this particular monologue,
and it already has the MP allocated, which is marked for MoH,
then just ignore the stop media command.
This is to not let the play media/stop media procedures

Both the play media and the music on hold use
the `media_player::call_play_media_for_ml()` as an entrance
towards the `media_player::media_player_new()` and
`media_player::media_player_play_init()`.
Prevent allocation of new MoH over ongoing one,
as well as the `play media` command over ongoing MoH.
Otherwise a media player will be re-used to override
ongoing activity.
Explicit policy must be used:
First the MoH has to be stopped
by getting back to the SDP `sendrecv` state, before
any other MoH request, or play media request can be fulfilled.
