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.

strictly event driven. The old implementation was rather process
like and the new one is still implemented as a process.

* Change retransmission scheme both for unicasts and for

broadcasts. Only count retransmissions that actually caused
transmission (according to the hardware).

Move misc. routines to new file.

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.
