The code in shell_ops.c that calls telnet_write will assert if it
returns non-zero. For a telnet shell it's normal that the
network might disconnect unexepectedly, so that should not
trigger an assert.

For code clarity, this commit adjusts the use of `return` statements
in functions with a void return type as follows:
- Transform `return foo();` into separate statements:
`foo();`
`return;`
- Remove unnecessary `return` statements when
they don't affect control flow.

Do not depend on init level but start the socket service
already in net core init because DNS init code depends on
socket service API to be ready to serve. And we call DNS
init at the net core init.

Rename write() to telnet_write(), and read() to telnet_read() so
that if we enable CONFIG_POSIX_API, the compiler will not complain
about those two functions as they conflict with POSIX API ones.

Current TELNET implementation wrongly assumed that if the command is
present, it will always be included at the beginning of the packet/data
buffer. Such assumptions however are not valid for STREAM sockets,
where the actual stream data could be fragmented in any way.
Therefore, the command parsing needed rework, so that we analyze each
byte received for the command escape code, and once received we enter
"command parsing" mode. Once no more commands are identified in a data
streak, the command bytes are removed from the data buffer before the
buffer is provided to the shell subsystem for processing.

Rework TELNET shell backend to use socket API for communication and
socket service library for socket monitoring.
Additionally, rework the TX part so that non-blocking TX is used when
sending from the system work queue. In case transfer is not possible at
the moment, the TX work is rescheduled instead of blocking the system
work queue.

If there's not enough networking buffers at certain moment,
they might become available later. So instead of closing connection
(and failing assertation) sleep and retry. This avoid the following
assertion failure when there's much of data to send:
net_pkt: Data buffer (1500) allocation failed.
net_tcp: conn: 0x20076024 packet allocation failed, len=1460

EAGAIN error is returned if the tcp window size is full. Retry
sending the packet instead of closing the connection if this
error occurs.
Also the full payload may not be sent in a single call to
net_context_send(). Keep track of the number of bytes remaining
and try to send the full payload.

Adding support for echo option if telnet commands are supported. This is
useful when the telnet client is in character mode. It allows to use the
arrow keys, ctrl-c and more. Something to keep in mind is that when
character mode is turned on by the client, network traffic is
considerably increased as each typed character is sent over the wire.
Note: echo mode is only supported if SHELL_TELNET_SUPPORT_COMMAND is
enabled.

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

When telnet client queries about remote echo support, we reply that we
won't do it (which reduces the traffic), however the echo was not
actually disabled on the shell. In result characters were double-echoed
in the character mode (by both local echo from the client and remote
echo from the server).

In case multiple commands were sent in a single packet, only the first
one was processed. Fix this by processing them in a loop.
As the subnegotiation command have variable length, and we currently
don't have any support for subnegotiation, stop processing packet when
