The f_ctx variable renamed in this change has a considerable variable
span. This makes the code hard to read as the variable name is neither
defined in the IEEE 802.15.4 standard nor can it be deduced from the
variable name.

Currently the insertion of an authentication tag requires a memcpy() call
and breaks encapsulation.
This change removes the need for memcpy() and improves the encapsulation
by calculating and reserving the required headspace early on while
keeping insertion where it belongs in the outgoing security procedure.
This is also a preparation for improved standard compliance of the
outgoing security procedure which is scheduled for a later commit.

This change makes the packet socket and ieee802154 l2 drivers aware of
AF_PACKET sockets, see https://github.com/linux-wpan/wpan-tools/tree/master/examples
for examples which inspired this change.

6LoWPAN fragmentation is not related to IEEE 802.15.4 proper but is just
part of its IPv6-specific L3-adaptation layer. To make this more obvious
we rename all resources related to 6LoWPAN fragmentation.

This change decouples the IEEE 802.15.4 (L2) layer from all IPv6 (L3)
concerns.
Applications may now choose to set CONFIG_NET_6LO=n and
CONFIG_NET_L2_IEEE802154=y at the same time.
Setting CONFIG_NET_6LO=n will build a vanilla IEEE 802.15.4-2006 specs
compliant L2 layer without any reference to 6LoWPAN or IPv6. This allows
application developers to design custom non-IP protocols on top of
IEEE 802.15.4-2006 and thereby makes the L2 layer much more re-usable.
Fixes#48585.
