Move some existing header inline code into source files.
Update coap_resolve_address_info() to remove need for client based app
code to have to understand IPv4/IPv6 code.
Remove IPv4/IPv6 specific code from examples code.
Update examples-code-check.c to cross-check NAME and SYNOPSIS entries.
Update examples-code-check.c to cross-check SYNOPSIS and RETURN VALUE entries.
Make the formating style of RETURN VALUES consistent.
This means that apps need to have no knowledge of what IP support is available.
Updates coap_uri_into_options() and coap_resolve_address_info()
which have only been recently added to develop branch and are not in any
previous release.
PR #1122 [1] has updated the reference to coap.space. As this site
provides a secure version but no redirect, the URI scheme is changed
to https.

If keepalive is enabled, make sure that they continue when a server
stops / starts. Limit the retry timeouts to the number of seconds
defined by coap_context_set_keepalive() so that interim NAT devices
are always kept "warm".
Addded in a new event COAP_EVENT_KEEPALIVE_FAILURE and updated docs
accordingly.
If the server is responding to a mcast request with a packet that is a
part of larger body (i.e. responding with Block2 option) the requests
for the missing packets have to be using unicast, which continues
to be supported.
The application can determine the unicast remote address before the next
coap_send() by using coap_session_get_addr_remote().
Add in a new function coap_session_get_addr_mcast() to get the mcast IP
if the client session was set up to talk to a mcast address.
Add in optional callbacks for when dynamic resources are setup and deleted.
Add in optional callbacks for when observe subscriptions start and stop.
Add in optional callbacks for when the observe counter is updated (can be
ratelimited) for a resource as well as track when a resource is deleted.
Add is support for new functions
Main functions with libcoap tracking support are
coap_persist_startup()
coap_persist_stop()
coap-server has -t option to track observe information.
UDP sessions supported, as well as OSCORE over UDP.
Documentation updated
libcoap tracking support (as opposed to application tracking) is configurable.
This allows for code reduction if not all logging levels are required.
Done by defining ./configure --enable-max-logging-level=X, where X can have
the value of 0 through 8 inclusive.
COAP_LOG_EMERG is always logged.
Can save up to 40k bytes.
