Figured out a way to split the "address" part of the buffer from the packet

data itself.  This makes for a much cleaner interface.

sys/divert.c
dll/divert.c
include/*.h
	DivertRecv and DivertSend now use IOCTLs instead of reads/writes.
	The 'address' parameter is passed by pointer to the driver, which
	writes directly to it (after sanity checks).
	This means that the data buffer now only contains the packet, which
	help to avoid some messy code.

examples/*/*.c
	Update the examples to reflect the new API.

doc/divert.html
	Update the documentation to reflect the new API.
