ee587244f4 net: ip: Enable Kconfig based debug options for the IP stack
It will be possible to enable/disable debug messages from IP stack from
make menuconfig, instead of modifying the relevant files to do so.

857017a9e3 net: contiki: Traverse UDP connection list properly
We have an array of UDP connections so just go through
the list in a most simple way. Set only the UDP connection
pointer if we found something and clear it otherwise.

This helps to avoid weird errors where multiple UDP connections
were added but only the first one was found during list traversal.

6f059122f7 net: contiki: Init UDP connection list properly
It is better to initialize the UDP connection array
fully in init instead of setting only the port number
to zero. This way we do not have any garbage bytes
left around.

4a21035141 net: uip: Traverse only through valid UDP connections
The uip6.c:uip_process() was not checking the upper bound of
the UDP connection list when traversing the connection list.
Now the code checks the upper bound of the array (UIP_UDP_CONNS)
and will not go beyond the max number of items in the array.

63512ac2f3 net: udp: Do not mark the packet to be dropped if received ok
If the udp packet was successfully delivered to the application,
and if the application did not want to send anything back to
sender, then then uip_slen(buf) will be 0.
In this case we MUST NOT set uip_len(buf) to 0 as that would
cause the net_buf to be released by RX fiber. In this case it is
application responsibility to release the buffer.

586f3adf6e net: Handle IPv6 packet reception
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.

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.
