Move the source code for these two modules out of src/sys/modules.

Drop <bsd.man.mk> support from <bsd.kmod.mk>.

Not objected to by: -current

Use .include <bsd.kmod.mk> to get to ../../*/conf/kmod.mk instead of
encoding the relative path.

Pull in sys/conf/kmod.mk, rather than /usr/share/mk/bsd.kmod.mk.
This means that the kernel can be totally self contained now and is not
dependent on the last buildworld to update /usr/share/mk. This might
also make it easier to build 5.x kernels on 4.0 boxes etc, assuming
gensetdefs and config(8) are updated.

$Id$ -> $FreeBSD$

Fixed bogus SRCS definition which broke `make depend'. Plain `make'
worked accidentally because the rule to generate ${OBJS} from ${SRCS}
is sloppy.

Fixed style bugs.

PCX loader for pseudo-device splash.
