* Removed tne preprocessor defines for coap_tick() and coap_clock_init() --
this made the code less readable and seemed to be of little use.
* Introduced the new type coap_time_t to represent wall clock time. On POSIX,
this is the number of seconds since the epoch, while on embedded systems
without a real time clock, this could be the number of seconds since the
last reboot. The new function coap_ticks_to_rt() is used to convert
coap_tick_t to coap_time.h. Currently, this is a division by COAP_TICKS_PER_SECOND
on all platforms.
* POSIX: coap_tick_t is now defined as unsigned long to avoid overflows in
coap_ticks().
Changed various functions to pass the local interface using the
new coap_endpoint_t abstraction. This change uses the functions
implemented earlier in commit 786ca6da (branch dcaf) but does not
use callback functions for network I/O.
This change closes bug #23 "server responds from wrong endpoint
(ipv6 address)" (POSIX only, CONTIKI and LWIP tbd).
Adding and removal of observes is now handled by libcoap. The application's
GET handler only needs to add the Observe option (see server.c:hnd_get_time()).
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.
* POST now returns Location header
* check critical options
* added option Accept from draft-bormann-coap-misc-06.txt
coap-client now has option -A to take list of accepted types
