This makes sure the bigger members are always list first in non-packed
struct to minimize the use of padding for alignment by the compiler.

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.

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.
Copied from Bluetooth sub-system.

Move packetbuf from net_buf to net_mbuf, update 802.15.4 stack
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
uip_driver.c|h does.

For commands that generate an intermediate zero status (e.g.
HCI_LE_Create_Connection) we should allow for successful
bt_cmd_send_sync() completion at this point. Since the code treats a
NULL return buffer as failure we must provide an actual buffer to
indicate success. There's not really any useful information in the buf
for a cmd_status but passing it to the caller lets us notify of the
successful completion.

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.
