Remove coap_list_t structure and replace with coap_optlist_t to maintain
backward code compatability.
Make use of the new coap_optlist_* functions
Use the new coap_optlist_t structure
Remove unneeded header includes
warn() -> coap_log(LOG_WARNING, )
debug() -> coap_log(LOG_DEBUG, )
As coap_send() automatically releases the specified pdu, it must
not be accessed after coap_send() has returned.
This change fixes CID 1458399 reported by Coverity scan.
The value of the observe option is kept for each resource rather than being global to the context.
The value of the observe option must wrap to be stay below 2^24.
The value of the observe option must be different from the initial value when a notification is sent.
Make coap_pdu-t independent of the header style.
Use C99 sized types when applicable.
Use transaction ids in host byte order in the library.
Make coap_pdu_t payload storage grow on demand.
Add parsing and encoding of PDUs with UDP or TCP style headers.
Adapt examples and unit tests to the new PDU format.
When building outside the source tree compilation fails on
examples, because the libcoap headers expect to be all in the
same directory but coap.h is generated under the build
directory, so it is necessary to add an extra include path
for it.
Also, build directories should always appear before source
directories in the include path, so that any leftover
generated files in the source tree are ignored.
Remember the query string used during the observe request and pass it to the resource handler.
Support partial notification of observers based on the query string.
The message id in the CoAP header is used for reliability when
transferring a CoAP PDU over a non-reliable transport protocol
such as UDP. For message de-duplication, it is useful to have
a monotonously increasing number space within a session. Therefore,
the context-global value has been moved to coap_session_t.
The function coap_new_message_id() now takes a coap_session_t
object as its argument.
In the main of examples/coap-server.c wait_ms was set to
COAP_RESOURCE_CHECK_TIME * 1000, then coap_run_once() was invoked
with parameter timeout_ms as COAP_RESOURCE_CHECK_TIME * wait_ms,
i.e., squaring the resource check time.
This bug has been fixed by removing COAP_RESOURCE_CHECK_TIME from
the call to coap_run_once().

coap-client now prints PDUs that are sent and received in log level
INFO so that these are output with '-v6' or higher. These messages
are now visible without turning on the full debug.
coap_async_state_t now contains a reference to the session that is
associated with the respective async state. As the response must
be sent over this session, the local_if parameter of check_async()
is not used anymore and can be removed.
coap_send() now takes ownership of the coap_pdu_t object passed
as second argument. Therefore, it is no longer necessary to release
the PDU structure in case of an error.
Zero-length strings passed to -u are valid user names for DTLS.
The function cmdline_read_user() therefore returns 0 when the
argument passed with option '-u' is an empty string.
Compact coap_address_t.
Use coap_queue_t for all queues.
OpenSSL warning for close alert should be info level.
Fix OpenSSL log level not working.
Use the application defined MTU in OpenSSL.
coap_log() optimization to avoid generating the log message text before testing the log level.
coap_can_exit() should check the new retransmit queues.
Fix retransmit time sometimes not correctly computed relative to sendqueue_basetime.
Add coap_write() API call for applications with their own main loop.
This change excludes the coap subdirectory from the include path
reported by pkg-config --cflags to avoid name conflicts with other
installed packages. Applications now must add the prefix 'coap/'
to include directives for libcoap header files, e.g.
#include <coap/coap.h>
Jean-Claude Michelou has reported this problem in Bug #82 [1].

A minimal Makefile now could look be written as:
PKG_LIBCOAP=libcoap-1
CPPFLAGS=$(shell pkg-config --cflags-only-I $(PKG_LIBCOAP)) -DWITH_POSIX
LDFLAGS=$(shell pkg-config --libs-only-L $(PKG_LIBCOAP))
LDLIBS=$(shell pkg-config --libs-only-l $(PKG_LIBCOAP))
Merge changes from PR #47 related to windows platform support.
Add full windows platform support including correct error checking and working regression tests and examples.
Remove need to build applications using libcoap with -DWITH_POSIX and to include coap_config.h. This applies to the examples as well.
