'RELENG_3_3_0_RELEASE'.

This commit was manufactured to restore the state of the 3.3-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

	+ ECP parallel port chipset FIFO detection
	+ DMA+FIFO parallel I/O handled as chipset specific
	+ nlpt updated in order to use the above enhanced parallel I/O.
	  Use 'lptcontrol -e' to use enhanced I/O
	+ Various options documented in LINT
	+ Full IEEE1284 NIBBLE and BYTE modes support. See ppbus(4) for
	  an overview of the IEEE1284 standard
	+ Detection of PnP parallel devices at boot
	+ Read capability added to nlpt driver to get IEEE1284 compliant
	  printer status with a simple 'cat /dev/lpt0'
	+ IEEE1284 peripheral emulation added to BYTE mode. Two computers
	  may dialog according to IEEE1284 signaling method.
	  See PERIPH_1284 option and /sys/dev/ppbus/ppi.c

All this code is supposed to provide basic functions for IEEE1284 programming.
ppi.c and nlpt.c may act as examples.

and local variables, goto labels, and functions declared but not defined.

basic i/o functions, bit-banging mechanism is implemented by dev/iicbus/iicbb.c
