Support clean exit for SIGTERM / SIGQUIT for valgrind testing.
Update all the coap_ calls to use the new API, and the updated structures.
Introduce using session instead of context.
Correct all the compiler warnings.
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.
From jsucaet's error description (Credits to Marc Haesen for revealing this bug):
The intent of the current code of coap_send is to release the allocated
memory upon success and not to release when an error has occured. However
this is broken (returning from coap_send with an error and a deallocated
pdu ptr is possible).
In the patch, I propose to let the calling function (of coap_send) be
responsible for free'ing the allocated pointer.
