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.
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.
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 implementation of option filters based on coap_opt_filter_t
has changed to improve support for long option numbers. An option
filter is now a sparse field of a fixed size that can hold up to
COAP_OPT_FILTER_LONG options with a number larger than 255, and
up to COAP_OPT_FILTER_SHORT options with a number of 255 or less.
The space taken by coap_opt_filter_t is
2 * ((((COAP_OPT_FILTER_SHORT + 1) >> 1) + COAP_OPT_FILTER_LONG) + 1),
or 12 bytes with the default settings for COAP_OPT_FILTER_SHORT == 6
and COAP_OPT_FILTER_LONG == 2.
Three new functions have been added to the option filter API:
* coap_option_filter_set() to store an option number in a filter,
* coap_option_filter_get() to check if a filter contains a given
option number, and
* coap_option_filter_unset() to remove an option number from a
filter.
The previously existing functions coap_option_setb(), coap_option_getb(),
and coap_option_clrb() continue to work on the new option filter
unchanged but now are deprecated.
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/.
