Alexander Aring cfce94653d 6lowpan: add support for getting short address
In case of sending RA messages we need some way to get the short address
from an 802.15.4 6LoWPAN interface. This patch will add a temporary
debugfs entry for experimental userspace api.

This patch changes the naming for interface private data for lowpan
intefaces. The current private data scheme is:

Alexander Aring 5609c185f2 6lowpan: iphc: add support for stateful compression
This patch introduce support for IPHC stateful address compression. It
will offer the context table via one debugfs entry.
This debugfs has and directory for each cid entry for the context table.
Inside each cid directory there exists the following files:

 - "active": If the entry is added or deleted. The context table is
   original a list implementation, this flag will indicate if the
   context is part of list or not.
 - "prefix": The ipv6 prefix.
 - "prefix_length": The prefix length for the prefix.
 - "compression": The compression flag according RFC6775.

This part should be moved into sysfs after some testing time.

Also the debugfs entry contains a "show" file which is a pretty-printout
for the current context table information.
