Implement socket poll function for TLS socket. In addition to regular
poll checks, we have to check if there is some decrypted data pending on
mbedTLS.

Add switch to a socket layer that will enable switching socket API to
TLS secure sockets. At this point there is no secure sockets
implementation, so secure socket calls redirect to regular socket calls.

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.
Remove some 'default ""' properties on string symbols too.
Also make definitions more consistent by converting some
config FOO
<type>
prompt "foo"
definitions to a shorter form:
config FOO
<type> "foo"
This shorthand works for int/hex/string symbols too, not just for bool
symbols.

If we use newlib the isdigit (and other similar functions) return an
error as char can possibly be viewed as signed:
usr/include/ctype.h:57:54: error: array subscript has type ‘char’ [-Werror=char-subscripts]
#define __ctype_lookup(__c) ((__ctype_ptr__+sizeof(""[__c]))[(int)(__c)])
Explicity cast to unsigned char so we deal with both this warning and
possible warning when -Wpointer-sign is enabled.

Having 24 parameters in a debug print is a bit extreme especially
as it is causing warning from new logger. Split the debug print
to three pieces each having 8 parameters which is more reasonable.

The problem is that net_if_call_timestamp_cb only checked if the
callback was registered for the PORT which invoked the whole action.
There is a possibility, that the callback will be registered, and packet
A will be passed to eth driver. Before the driver is finished with
packet A, network layer will start handling another packet (B) - so it
will unregister the callback for packet A and register it for B. After
that the network driver will finish processing packet A and invoke the
timestamp callback. The mechanism would then only check if a callback is
registered for the port of the driver and invoke the callback for the
packet that was registered earlier (so A instead of B).
This commit fixes that by storing info not only about the port but about
the packet too.

Do not clear pending PDELAY_REQ pointer when sending a new one.
Unref the state->tx_pdelay_req_ptr first and only then set the

Make sure that the calculated ratio values are used just once.
Without this, if the ratio is even insignificantly larger than 1, the
actual clock quickly drifts to really large numbers. This causes the
sync procedure to restart too often.

The problem with the previous approach was that the response timestamp
callback which calls net_pkt_unref could be skipped if the callback was
already registered for another packet. The net_pkt_ref function was
always called which led to memory leaks.
This commit simply disallows handling multiple pdelay requests at once.
If the timestamp callback is already registered, the received request
will not be handled.

The issue was that the length field of the tlv extension in the sync
follow up packets was wrong. It is supposed to skip the length of the
header of that extension. The easiest fix was separating the header and
the actual contents into separate structs and that's what this commit
does.

This allows zephyr to listen LLMNR DNS queries sent by Windows
and respond to them. See RFC 4795 for details.
The feature requires that hostname is set properly to the
zephyr device and LLMNR is configured properly.
Typically following config options are enough for this support:
CONFIG_NET_HOSTNAME_ENABLE=y
CONFIG_NET_HOSTNAME="zephyr-device"
CONFIG_DNS_RESOLVER=y
CONFIG_LLMNR_RESPONDER=y

An ARP entry, if not free, will be either in pending list or in the ARP
table. What differentiate both is the type of data they hold: either a
pending packet or an actual ethernet address.
It is then possible to unite these 2 attributes to save 4 bytes
per-entry.

Until now, each ARP entry had a k_delayed_work to be used as a timer
when the ARP entry is a pending one, waiting for the ARP request to
succeed in order to get to the ARP table.
But k_delayed_work is not a small object (40 bytes). Thus reworking the
ARP request timer by having one central k_delayed_work and a timestamp
in every ARP entry properly handled at every timeout (1+ entry might
have reached the timeout then).

Instead of looping over the entries array, which will keep the same
order, let's use slist: one for free entries, one for pending ones and
finally one as the actual ARP table.
This permits some optimizations in how to look up and making small
heuristics by changing entries order when it seems relevant.
