IP packet passing through 6lowpan compression and 802.15.4
fragmentation has an issue. (RFC 6282 and 4944) RFC4944, 5.3
says "fragment header's datagram_size and datagram_offset
values as the size and offset of the IPv6 datagram before
compression".
At the moment datagram size and offset values are after
compression. Due to multiple bearer (15.4 and bluetooth) support
and multiple incoming buffers support functionality is divided
to compression and fragmentation parts. And datagram size and
offset values for BT are after compression. Small packet (which
doesn't need fragmentation) doesn't go through this. So cacheing
compressed and uncompressed header lengths and with hdr difference
preparing fragments as per original buffer (total buf size and offset).

When using the CSMA MAC driver, a new packet can be queued before
all the fragments of the previous one were sent. The transmit_packet_list()
function will start sending the old fragments with the new net_buf context.
Keep a per-context neighbor_list to avoid that

Adds extern "C" { } blocks to header files so that they can be
safely used by C++ source files.

The IP and L2 buffer debugging is now activated if one enables
CONFIG_NETWORKING_WITH_LOGGING option.

Because the L2 buffers are only used by 802.15.4 sub-system,
we must not compile and link them to the kernel.
