On processing a DNS server option, which re-initializes the DNS resolve
context, also cancel all pending DNS queries before closing the old DNS
resolve context. Otherwise, `z_clock_announce()` will later work on the
re-initialized context once the queries expire and crash because the
reference to the timeout function `query_timeout()` has been cleared.

The earlier code was always queuing the FIN that is sent when
connection is closed. This caused long delay (200 ms) before the peer at
the other end noticed that the connection was actually closed.
Now check if there is nothing in the queue, then send the FIN
immediately. If there is some data in the queue, flush it when a valid
ack has been received.

With `CONFIG_NET_NATIVE`, offloaded drivers can specify capabilites with
`NET_IPV4/6` configs, so there is no longer need to handle socket
offloading separately.
Also, initialize hints structure with zeros, as according to man pages
unused fields should be set to 0:
`All the other fields in the structure pointed to by hints must contain
either 0 or a NULL pointer, as appropriate.`

Randomly generating ID the first time coap_next_id() is called is more
in accordance with CoAP recommendations (see
https://tools.ietf.org/html/draft-ietf-core-coap-18, section 4.4)
"It is strongly recommended that the initial value of the
variable (e.g., on startup) be randomized, in order to make successful
off-path attacks on the protocol less likely."
Doing this in a dedicated init function is the cleanest and most
idiomatic approach. This init function is not exposed publically which
means it will be called only once, by the network stack init procedure.

The main and idle threads were being defined statically,

value. This wastes a bit of memory and isn't accessible
to user threads anyway, just expose the actual thread
objects.
