Since the 4-byte CPU ID on native is in most cases generated from the 2-byte
PID of the native process, choosing the lower half of the hash of the CPU ID to
set the radio address led to always setting it to the hash of 0 in this
cases. This changes it to use both halves of the hash and taking the
modulus so this corner cases can be avoided.
udp_recvfrom wrote the sender port number in host byte order into the
provided sockaddr6_t. Because all send functions expect the port number
in network byte order this introduces a superfluous conversion step in
case one wants to reuse the address for replying.

Added debug output that warns about packets that are dropped
because the transceiver buffer was full or because the transceiver
failed to notify aiting upper layers.
Boards should define HWTIMER_SPIN_BARRIER that is used to decide
whether it makes sense to set a timer and yield or call hwtimer_spin
instead.
Used by `core/hwtimer.c` and `sys/vtimer/vtimer.c`.
A default value is provided and a warning is printed when it is used.
`bloom_t` is defined as a struct.
`_t` can mislead the user to think of bloom_t
as a typedef (see our coding conventions) instead of a struct.
Thus, I modified `struct bloom_t` to be a *typedefed* struct.
Another solution would be to rename bloom_t to sth. like bloom_s
everywhere and use `struct bloom_s` instead of `bloom_t`.
Currently, the tcp and udp implementations are bound to each other in a
module called *destiny*. Thus, when using only one of them then the
other one gets also compiled into the binary and initialized,
which results in unnecessary RAM usage and workload for the CPU.
The approach in this PR defines a common module named *socket_base*,
which contains functions used by the posix layer. Compiled by it's own,
those functions return negative error codes, to symbolize upper layers
that they are not supported. When also including the modules *udp* or
*tcp* respectively, functions from *socket_base* get overwritten with the
correct functionality.
Defining *udp* or *tcp* in a Makefile also includes *socket_base*.
Defining *pnet* in a Makefile also includes *socket_base*.
If there's no IPv6 address configured so far to any interface, 6lowpan
should not try to handle incoming packets. This can easily lead to
looping packets.
The transceiver check if it is already running when initializing.
However, this check was done by comparing its pid for >= 0, which is not
sensible anymore since valid PIDs only start at 1.
In many places we needlessly use `sched_active_thread->pid` whilst we
already have `sched_active_pid` with the same value, and one less
indirection.
`thread_getpid()` is made `static inline` so that there is no penalty in
using this function over accessing `sched_active_pid` directly.
Quoting myself:

In #1564 we came to the conclusion that we don't need this code.
Closes#1564.
This is a malloc-free implementation of the Concise Binary Object
Representation (CBOR) data format for the RIOT-OS.
This implementation mostly stand-alone, and it should be pretty easy to
port to other platforms. We're only using the C STL and some custom
network-related functionaliy which could be easily replaced by depending
on arpa/inet.h.
The CBOR API is straight-forward to use and provides encoding/decoding
functionality for all major C types, such as:
- int
- uint64_t
- int64_t
- float
- double
- char*
- struct tm
- time_t
It is possible to conditionally compile this module via CFLAGS:
- CBOR_NO_SEMANTIC_TAGGING: All semantic-tagging features removed
- CBOR_NO_CTIME: All ctime related features removed
- CBOR_NO_FLOAT: All floating-point related features removed
- CBOR_NO_PRINT: All features depending on printf removed
`tcp_t::stack_size` is only examined by the shell command `ps` and
`DEBUG_PRINT`. For the latter one only if `DEVELHELP` was enabled.
This PR guards the member `tcp_t::stack_size` in `#ifdef DEVELHELP`.
Only if DEVELHELP was activated its value get printed by `ps`.
Closes#1287.
Instead of using differing integer types use kernel_pid_t for process
identifier. This type is introduced in a new header file to avoid
circular dependencies.
