The uip_ds6_nbr_get_ll() returns const addr but we need to
overwrite the addr so cast is needed here.
The const pointer returned by nbr-table.c:nbr_table_get_lladdr(),
which is called by uip_ds6_nbr_get_ll(), actually points to
neighbor cache which is dynamic and will never be stored in read
only memory, and thus is safe to cast to non-const.

This mega patch changes how Contiki uses buffers. In standard
Contiki there is only couple of static and global buffers.
This makes the stack non-reentrant and only usable in one
thread. This patch replaces the global buffer with buffer
supplied by caller (net_buf.h). The Contiki stack is still not
fully re-entrant after this (packet reassembly needs more TLC)
but it is a good start.

bonded devices:
'The Client Characteristic Configuration descriptor value shall be
persistent across connections for bonded devices. The Client Characteristic
Configuration descriptor value shall be set to the default value at each
connection with non-bonded devices'.
To handle this now each configuration has a valid field indicating if the
configuration is valid.

this way need to be processed without delay and through a separate
