Call relevant Contiki uIP functions to setup the internal
structures in the uIP stack.

Jukka Rissanen 6ba3a02eed net: uip: Avoid casting warning when accessing link local addr
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.

Jukka Rissanen 251a45b602 net: Use our network buffers instead of global ones in Contiki
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.

Jukka Rissanen 3633410706 net: uip: Pack and alias network buffer related structs
We need to make sure that the structs that are cast to received
network buffer are packed. We also need to enable __may_alias__
attribute for these structs in order to avoid "dereferencing
type-punned pointer" warnings.

Variable called "initialized" is only needed if the nameserver
pool size is bigger than 1 (UIP_NAMESERVER_POOL_SIZE > 1).

has UIP_TCP or UIP_CONF_IP_FORWARD defined.

Real timer implementation needs function prototypes.
This is just to satisfy the compiler. Needs more TLC.

Jukka Rissanen 75d4b3f0c2 net: Initial networking support
Base is from Contiki git tree at git://github.com/contiki-os/contiki.git
commit 6ac939bc58ea76aa37e9b86af55ad51cfc3434e9

This one does not do anything useful yet. It sets the baseline for
subsequent patches.
