Fixed problem with the radio driver changing transmission power to max when not specified at transmission. Also fixed bug where the lock was released when setting the transmission power.
...
Thanks to Djamel Djenouri and Marcus Lundén for identifying the problem.

Renamed the rimebuf module to packetbuf to signal that the module is used outside of a pure Rime context (e.g., the sicslowpan code uses it).

There is problem with the CC2420 driver: under high traffic load the packets often get mangled in the receive FIFO. Not sure why this happens or how to best prevent it. As a temporary workaround, I've added an additional CRC16 check to the incoming packets. This eats two bytes from each packet, but at least protects against the erroneous packets we've seen quite a few of lately. The reception code was also cleaned up, which resulted in a smaller code size.

Change typedef of uip_ipaddr_t from a vector type to a union.

typedef union uip_ip4addr_t {
u16_t u16[2];
u8_t u8[4];
} uip_ip4addr_t;
typedef uip_ip4addr_t uip_ipaddr_t;
This implies that one must consistently pass pointers to
uip_ipaddr_t:s and not mix and match pointers with
uip_ipaddr_t:s as was done earlier.
