Olaf Bergmann 909cccd05d Support for response code 7.31 to cancel observation relationships. 
This new behavior is described in Section 4.6 of draft-ietf-core-observe-12.
The idea is to send a response with code 7.31 and the token to identify
the subscription.

chrysn 205520b601 zero-copy package reception 2013-11-17 16:53:08 +01:00
chrysn 1961caeebc use lwip pbufs for pdu allocation 
so far, this only replaces the allocator; it is not used yet for
zero-copy operations.

chrysn e32a0f3497 add coap_add_option_later function 
the coap_add_option_later works like coap_add_option, but does not take
data. instead, it allocates the option empty, and returns an address the
application has to fill with data later.

this is especially useful for the etag and block options; the
application can write out its variable data, generate a checksum while
writing, and fill the etag when the data is already written to the pdu.
with the block options, the more flag can be set at the last moment.

Olaf Bergmann c6412f2038 Rework of option parser to support "Klaus encoding" (coap-13), unit tests 
The subdirectory "tests" now contains a growing set of unit tests for the
libcoap API. To use this, you will need CUnit (see http://cunit.sourceforge.net)
and must configure with the option --with-tests.
