ffmpeg's CNG expects a fixed frame size, or at least a maximum frame
size, as it allocates internal buffers on construction based on that
frame size. Calling the decoder with a larger frame size therefore leads
to an internal buffer overflow. Calling it with a smaller frame size is
fine.
Retain the simple one-shot CNG for the most common case (frame size
smaller than the max). For larger frames, call the CNG in a loop and
manually construct a return frame.

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`.

Make both `media_player_opts_t.db_id` and `media_player_content_index.db_id`
unsigned because:
- they aren't used with any guards/init values
- most DB-media API functionality actually uses `unsigned long long`
So this makes the ids consistent with the usage of them
in the actual code.

To not leak on media changes (ssrc differs), release
previous `->ssrc_out`, then overwrite the pointer.
`get_ssrc()` returns an owned reference.

Before to start the media player, check if the
seek process for the start frame failed, because
otherwise it starts from the unexpected position,

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

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".
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.

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.
