Make tcpip_input() to return 0 if there is an error when
processing the packet. Value != 0 indicates a successfull
packet processing and in this case the application will
free the packet.

Assign local UDP port number if not explicitely set by the caller. Use
the timer as a source of uniqueness as there is no random function
available.
If the local UDP port number has been set, verify that it is available
and not already assigned.

When read from the Rx FIFO, pass the network buffer to the uIP IPv6
stack using the tcpip_input() function. As the event is handled, not
all cases where the buffer is to be discarded can be detected.
Thus, if ICMPv6 errors will not be sent, indicate that the packet is
to be dropped by setting its length to zero.

To make it easy to periodically verify that we have sane stack sizes
it's helpful to have some code to evaluate how much of the stacks are
used. There's already a CONFIG_INIT_STACKS option which pre-fills the
stacks with 0xaa bytes, so we make use of it and in case the option is
enabled run the extra code to evaluate how much of each stack was
used. The trigger for the evaluation is a disconnection event.

with net_mbuf (which is smaller in size, and mostly wrapper for
packetbuf) and split sicslowpan(ipv6/sicslowpan.c|h) functionality
to compression and fragmentataion. This patch contains
null_compression and null_fragmentation which is exactly what

We do not need large 1280 bytes long buffers in lower IP stack
layers. After long packet has been fragmented to smaller chunks
it depends on the radio technology how long buffers we need
to use. For 802.15.4 we can use 128 bytes long buffers.

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.
