Modified Files:
	src/share/man/man4: ugen.4
	src/sys/arch/i386/conf: GENERIC GENERIC_LAPTOP
	src/sys/dev/usb: files.usb ugen.c usb.h

Log Message:
Add UGEN_BULK_RA_WB, which allows users of ugen(4) to request read
ahead and write behind, improving performance for the Universal
Software Radio Peripheral (USRP) used with GNU Radio.

Enable UGEN_BULK_RA_WB in GENERIC and GENERIC_LAPTOP; behavior is
unchanged unless the new ioctl is called.

This code was written by Joanne Mikkelson under funding from DARPA's
ACERT program.
