coap_malloc_type() and coap_free_type() provide an abstract API for
dynamic memory management on different platforms. resource.c still
is in transition and needs more cleanup.
The CoAP resource management is based on uthash and utlist for
platform POSIX but used a custom list implementation for Contiki.
This modification replaces the list handling by utlist macros
entirely. A set of convenience macros has been defined to access
the resources stored in a CoAP context with respect to the
preprocessor symbol COAP_RESOURCES_NOHASH.
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.
* 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().
On some systems we must the struct in_pktinfo and in6_pktinfo defining
by ourself. But on POSIX systems the definition is made by the header
netinet/in.h, so check if there is a flag HAVE_NETINET_IN_H been set and
skip the self made definition.
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/.
