35a2519091 net: l2: ppp: add generic function for handling Conf-Req
Introduce new ppp_config_info_req() function that can be used in order
to handle options received within Conf-Req packet. As an input it takes
array of supported options. If received Conf-Req packet contains unknown
options, then a Conf-Rej packet is automatically generated with all of
those options. If all of received options are supported, then function
continues to parse each provided option individually by calling option
specific callbacks.

5326d11e8c net: l2: ppp: add generalized "my options" negotiation
So far there was no generalized way how to handle negotiation of "my
options" (those sent with Conf-Req packet to peer). Peer response for
proposed options and their values were not tracked in any way, so
rejected (by peer) options were sent over and over again in subsequent
Conf-Req packets. In case of IPCP it means that all sent options such as
IP_ADDRESS, DNS1, DNS2 were mandatory for being supported by peer in
order to successfully finish negotiation. For example if 'pppd' was the
configured peer (e.g. when using with QEMU and net-tools scripts),
without ms-dns being configured (which is the default), then "my
options" negotiation failed.

Introduce generalized mechanism for negotiating "my options", so it is
easier to maintain current set of supported options and easily add new
options to the implementation in future. FSM instance inititialization
function can provide information about supported "my options".
Information is is passed as a table of 'struct ppp_my_option_info'
containing:

 * option code (type),
 * callback for adding option to Conf-Req packet,
 * callback for received Conf-Ack with that option,
 * callback for received Conf-Nak with that option.

Store also runtime information about each negotiated option. First of
all remember which options have been rejected, so they are not sent to
peer once again in the next Conf-Req packet. This will solve issue with
IPCP negotiation when peer doesn't support DNS1 or DNS2 options. Keep
also track about which options have been acked, so such information can
be verified before bringing FSM instance up.

f0f56ff773 net: l2: ppp: generalize option parsing function
Rework implementation of ppp_parse_options() to be more generic and
flexible to use. Pass callback and user data for parsing each option
separately.

Keep old functionality of ppp_parse_options() accessible via
ppp_parse_options_array() function. This will make sure that old code
using this function doesn't need to be changed now. There are plans
however to remove ppp_parse_options_array() once there are no more users
of it in future.

08988999ca net: l2: ppp: prepare Configure-Req with net_pkt API
Use net_pkt API to assemble Configure-Req messages. Compared to net_buf
API it allows us to simplify code.

Remove append_to_buf() helper functions, as their functionality is now
totally replaced by net_pkt API. Additionally net_pkt API handles data
that wraps several net_buf packets, which was not the case with
append_to_buf().

50b2cafc42 net: l2: ppp: use net_pkt API for replying to Configure-Req
Use net_pkt instead of net_buf API for replying to Configure-Req. We use
the fact that for now we reply with either Configure-Ack or
Configure-Rej only. In both cases we can allocate net_pkt ahead, because
we know its maximum length (which is equal to length of received
Configure-Req packet).

Make also an improvement in generic FSM code and reply with
Configure-Rej to all Configure-Req for which there is no config_info_req
callback set. Use that to drop LCP specific Conf-Req handling code,
because there is no option properly supported there yet.

b091181fa5 net: l2: ppp: rework ppp_parse_options() to return error code
So far ppp_parse_options() has returned enum net_verdict. This type was
never used directly by network stack. Instead, caller was always
checking for NET_OK and returning error code in case of failure.

Change implementation of ppp_parse_options(), so it returns error code
in case of error and 0 when succeeded. This better fits its generic
purpose.

The problem showed up after a recent OpenThread upmerge, where changes

`otJoinerStart` call can be preempted by the OT thread, leading to an

aec5f0a3ef net: mqtt: Prevent double CONNACK event notification on server reject
Currently, the application could receive a duplicate CONNACK event, in
case the server rejected the connection at MQTT level (with an error
code provided with CONNACK message). A subsequent connection close (with
`mqtt_abort` for instance) would produce the duplicate event.

Fix this by reporting back to the MQTT engine, that the connection was
refused, so it can close the connection rightaway. Rework the event
notification logic, so that DISCONNECT event instead of a duplicate
CONNACK event is notified in that case.

Also, prevent the MQTT engine from notyfing DISCONNECT event in case of
socket errors during initial connection phase (i. e. before
`mqtt_connect` function finished).

3c2d0f37a3 logging: avoid identifier collisions
MISRA-C Rule 5.3 states that identifiers in inner scope should
not hide identifiers in outer scope.

The log output instances all named "log_output" in backends
collide with the "log_output" parameter of various functions.
This renames the variables in the backends to make them
more descriptive. Same goes for the buffers for some of
these instances as they are all named "buf", and "hostname"
being used in the network backend,  so they are renamed.

There are a few places where variables are overriden within
an inner scope (e.g. inside loop and if block) so they are
also renamed.
