Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

+ *	NET3:	Support for 802.2 demultiplexing off Ethernet (Token ring
+ *		is kept separate see p8022tr.c)

+ *
+ *		Demultiplex 802.2 encoded protocols. We match the entry by the
+ *		SSAP/DSAP pair and then deliver to the registered datalink that
+ *		matches. The control byte is ignored and handling of such items
+ *		is up to the routine passed the frame.
+ *
+ *		Unlike the 802.3 datalink we have a list of 802.2 entries as
+ *		there are multiple protocols to demux. The list is currently
+ *		short (3 or 4 entries at most). The current demux assumes this.
