Instead of using 32 bit enum values for event numbers, convert
the code to use 64 bit long bit fields. This means that the
user API is changed to use 64 bit event values instead of 32
bit event values.

If we're parsing a CoAP request with an observe option of '1', but there is
no matching observer, return an error instead of returning a zero.

If the CoAP server receives a message that doesn't fit into the receive
buffer, we should stop processing the message and respond to the client
with 4.13 "Request Entity too large".

CONFIG_ZVFS_POLL_MAX is now used to control the maximum number of poll()
entires. Thereby, CONFIG_NET_SOCKETS_POLL_MAX is redundant and shall
be deprecated.
Modify the defaults for NET_SOCKETS_POLL_MAX and ZVS_POLL_MAX so that
the deprecation actually makes sense instead of symbol removal. In case
the application still sets the old config, it will modify the
ZVS_POLL_MAX default.

There's not much to be done in case waking up the server thread with
socketpair send() fails, but at least we can log an error on such event
(to please coverity).

Update coap_service_send and coap_resource_send to take an optional
pointer argument to the newly introduced coap_transmission_parameters.

Replace function parameter 'retries' with pointer to structure
holding coap transmission parameters. This allows setting the
retransmission parameters individually for each pending request.
Add coap transmission parameters to coap_pending structure.
Update migration guide and release notes.

The CoAP request handler returns errno codes in the following cases:
* ENOENT if no handler found; respond with 4.04
* ENOTSUP if an unknown request code received; respond with 4.00
* EPERM no handler found for the method; respond with 4.05

A CoAP client can re-issue an observe request (same endpoint and token)
to refresh it's subscription. No new observer should be registered in
this case.
