Jon Shallow 21e045bb8f coap-server: Make sure observe updates are sent off asap ...

examples/coap-server.c:

Track time spent in the epoll branch for the select() and coap_io_process()
calls to correctly adjust wait_ms.

Adjust wait_ms to be the remaining amount in the current second, so that
any 'time' observers get the updated time just after the new second starts.

include/coap2/net.h:

Add in support to track that an observe is pending transmission - primarily
a saving of needing to look up if a observe needs to be sent.

include/coap2/resource.h:

Add in support to track the context that 'owns' a resource.

src/resource.c:

Track the context that 'owns' a resource in coap_add_resource().

Track the fact that when we are making a resource partially dirty by recording
that an observe is pending in coap_notify_observers().

In the epoll case, make sure that timerfd triggers immediately when a pending
observe is set so that the application will return immediately from any select()
etc. call to process the libcoap outstanding activity (in particular pending
observes) in coap_resource_notify_observers().

Only call coap_notify_observers() in coap_check_notify if there are any
observes pending.

man/coap_observe.txt.in:

Minor clarifications in the examples.
