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.
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.
Issue #37 [0] argued that coap_split_uri() should not change the
string that was passed as its first argument. The old behavior
was to normalize the scheme and the host part of the given URI by
converting both to lower case. This commit drops that normalization
step and leaves the original string as is. As a consequence,
implementations that employ virtual hosts now must canonicalize
the host part by themselves.
CAUTION: The constness is not (yet) reflected in the str components
of the result parameter of type coap_uri_t. Care must be taken not
to accidently change an immutable component of the coap_uri_t object.

Resume the cleaning of the public header files, no functional changes.
Reformatting the infos in the head of the header files, restructure header
inclusion check to be more generic. Reorder some include directives in a
alphabetical order. Remove including instructions for C++ stuff, it's
already done in the coap.h header, and the user only has to include this
header file.
Dropping the prefixing of the include guarding of uthash.h because it would
cause trouble with the macro handling in TinyDLS.
Thanks Olaf for reminding this!
The parser iterator did not break up URIs correctly. As this
cannot be fixed easily, the parser iterator has been removed.
coap_split_path_impl() now operates directly on the message
buffer instead of the iterator abstraction.
This bug also caused t_parse_uri12() in the URI test suite
to fail.
In preparation for changing the make buildsystem to a fully autotools
controlled system moving the core libcoap source files to a better logical
place.
All the library related header files moving to include/coap/ to get
all the public and local header files in a separate place. Also moving
the C source files of the libcoap library to the folder src/.
