The sk(4) driver has moved to /sys/dev/sk

Remove bridge(4) from the tree. if_bridge(4) is a full functional
replacement and has additional features which make it superior.

Use a consistent style and one much closer to the rest of /usr/src

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.

Reoganize/update the SysKonnect driver:

- Break out the support for the XMAC II's PHY into an miibus driver.

- Reorganize the probe/attach stuff using newbus. Each XMAC is now
attached to the parent GEnesis controller using newbus. This is
necessary since each XMAC must also have an attached miibus, and
the miibus read/write register routines need to be able to get
at the softc struct for each XMAC, not the one for the parent
controller. This allows me to get rid of the grotty code I added
for selecting the unit numbers for the ifnet interfaces: the unit
numbers are now derived from the newbus-assigned unit numbers,
which should track with the ifnet interface numbers. I think.
At the very least, there should never be any collisions.

- Add support for the SK-9821 and SK-9822 1000baseTX adapters. Special
thanks to SysKonnect for loaning me two adapters for testing.

Add ${DEBUG_FLAGS} to CFLAGS in bsd.kmod.mk, not in scattered module
makefiles. Bad examples in fxp/Makefile keep getting copied to new
makefiles.

Removed special rules for building and cleaning device interface files
and empty options files. The rules are now generated automatically in
bsd.kmod.mk. Cleaned up related things ($S and ${CLEANFILES}).

Zap some unused echo "#define NFOO 1" > foo.h style defunct stuff.

Don't generate 'bpf.h' since it's not used.

Change the name of the installed KLM to contain a leading "if_".
Except for miibus which is now installed as miibus.ko.

$Id$ -> $FreeBSD$

Convert the VIA Rhine driver to newbus and set it up to be compiled as
a module. Also modified the code to work on FreeBSD/alpha and added
device vr0 to the alpha GENERIC config.

While I was in the neighborhood, I noticed that I was still using
#define NFPX 1 in all of the Makefiles that I'd copied from the fxp
module. I don't really use #define Nfoo X so it didn't matter, but
I decided to customize this correctly anyway.

Create module directories for the xl, ti, tl and sk drivers and add
them to the Makefile so that modules will be generated for /modules.
