Remove option headers that do not exist and are not used
from the Makefiles in sys/modules.
(opt_devfs.h, opt_bdg.h, opt_emu10kx.h and opt_uslcom.h)

add an option BKTR_USE_FREEBSD_SMBUS that enables compiling the module

Let modules use the kernel's opt_*.h files if built along with
the kernel by wrapping all targets for fake opt_*.h files in
.if defined(KERNBUILDDIR). Thus, such fake files won't be
created at all if modules are built with the kernel.

Some modules undergo cleanup like removing unused or unneeded
options or .h files, without which they wouldn't build this way
or the other.

We don't need to generate vnode_if.h anymore

Add a overhaul of the soundchip initialization for the MSP34xx chipsets
found only many tv-cards.

We currently use more ore less evil hacks (slow_msp_audio sysctl) to
configure the various variants of these chips in order to have
stereo autodetection work. Nevertheless, this doesn't always work
even though it _should_, according to the specs.
This is, for example, the case for some popular Hauppauge models sold
sold in Germany.

However, the Linux driver always worked for me and others. Looking at
the sourcecode you will find that the linux-driver uses a very much
enhanced approach to program the various msp34xx chipset variants,
which is also found in the specs for these chips.

This is a port of the Linux MSP34xx code, written by Gerd Knorr
<kraxel@bytesex.org>, who agreed to re-release his code under a
BSD license for this port.

A new config option "BKTR_NEW_MSP34XX_DRIVER" is added, which is required
to enable the new driver. Otherwise the old code is used.

The msp34xx.c file is diff-reduced to the linux-driver to make later
modifications easier, thus it doesn't follow style(9) in most cases.

Remove bktr.h/NBKTR. Set BKTR_FREEBSD_MODULE in opt_bktr.h instead.

Fix kernel build.

Major rework of the iicbus/smbus framework:

- VIA chipset SMBus controllers added
- alpm driver updated
- Support for dynamic modules added
- bktr FreeBSD smbus updated but not tested
- cleanup

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

Update to build both bktr and bktr_mem modules
