Contribution description

This adds the capability to nanocoap_server to send separate response, that is a delayed response outside the CoAP handler.
The CoAP handler will first send an empty ACK (if the request was conformable), then some other function can send the actual response at a later time, using nanocoap_sock_send_separate() with the request context information serialized into nanocoap_sock_response_ctx_t.

Testing procedure

A /separate endpoint was added to examples/nanocoap_server:

$ aiocoap-client coap://[fe80::748f:e6ff:fed7:426d%tapbr0]/separate
This is a delayed response.
