pico_tree_insert: check return value and free memory if needed

Issue #387: Added some more checking/freeing stuff/todos

[IEEE802.15.4] - refactored

Issue #387: Check return value of pico_timer_add() and pico_timer_add_hashed()

Coverity IDs 65624/65625: Cast 32-bit operand in time calculations to
pico_time(64-bit) instead of casting the result of the calculation to pico_time
This prevents overflowing of the 32-bit calculation before casting to
pico_time

IPv6-ND: Ensure no null-pointer deref

[6LoWPAN]- Added check for globally routable prefix in enable_6lbr-routine. So specifying an invalid prefix will result in error.

[6LoWPAN] - Fixed couple of issues:

* Added small queue for duplicate forwarding suppression
* Fixed memory leak when frames were considered a duplicate
* Fixed duplicate ping-request when a new ping-entry was added to the routing-table
* Duplicate suppression is now based on origin-, final-addresses and sequence-number, for BCAST-frames the sequence number is that of the BCAST header.
* Fixed issue were BCAST frames weren't forwarded because sixlowpan_is_duplicate was checked twice.
* Added check for nodes to if they are not themselves the originator of the frame, if this is the case, the frame is discarded.

TODO - refactor memmove

[6LoWPAN-ND] - 6LNs now sends neighbor solicitation via unicast to router with Address Registration Option (ARO) to check for duplicates. Confirmation on router-side TODO.

Yay, a commit in the dashboard again!
[6LoWPAN-ND] - Now hosts also start retransmitting router solicitations when their default router becomes unreachable

[6LoWPAN-ND] - Hosts retransmit router solicitations when no default router configured, lifetime expires
