[sane-devel] adding dev/ppbus/ppi.h detection to configure

[stef]

	Hello,

	I'd like to have sane configure script detecting the dev/ppbus/ppi.h
file. On freebsd, this file is associated with the /dev/ppi0 device which lets users
accessing the parallel port through a few ioctls, instead of doing inb/outb.

	I have already modified the umax_pp backend to make us of it. But I need 
sane to set HAVE_DEV_PPBUS_PPI_H


	Would be patch for configure.in:
diff -ur --new-file sane-backends-1.0.11/configure.in sane-backends-1.0.11-umax_pp/configure.in

	And for config.h.in:
