Use the operations on 802.15.4 header structs introduced in a previous
patch to create and parse all headers in the mac802154 stack. This patch
reduces code duplication between different parts of the mac802154 stack
that needed information from headers, and also fixes a few bugs that
seem to have gone unnoticed until now:
* 802.15.4 dgram sockets would return a slightly incorrect value for
the SIOCINQ ioctl
* mac802154 would not drop frames with the "security enabled" bit set,
even though it does not support security, in violation of the
standard

The struct as currently defined uses host byte order for some fields,
and most big endian/EUI display byte order for other fields. Inside the
stack, endianness should ideally match network byte order where possible
to minimize the number of byteswaps done in critical paths, but this
patch does not address this; it is only preparatory.

Add support for communication over IEEE 802.15.4 networks. This implementation
is neither certified nor complete, but aims to that goal. This commit contains
only the socket interface for communication over IEEE 802.15.4 networks.
One can either send RAW datagrams or use SOCK_DGRAM to encapsulate data
inside normal IEEE 802.15.4 packets.
Configuration interface, drivers and software MAC 802.15.4 implementation will
follow.
Initial implementation was done by Maxim Gorbachyov, Maxim Osipov and Pavel
Smolensky as a research project at Siemens AG. Later the stack was heavily
reworked to better suit the linux networking model, and is now maitained
as an open project partially sponsored by Siemens.
