Fix typo; s/ouput/output

Remove bus_{mem,p}io.h and related code for a micro-optimization on i386
and amd64. The optimization is a trivial on recent machines.

Remove support for FreeBSD < 4.recent from this driver.

Remove vnode.h and adjust includes to compensate for pollution.

Move the bktr(4) <arch>/include/ioctl_{bt848,meteor}.h files to dev/bktr
as these ioctl's aren't MD. This also means they are installed in
/usr/include/dev/bktr now. Also provide compatability wrappers for
where these headers lived in 4.x.

Use __FBSDID().
Also some minor style cleanups.

Prefer new location of pci include files (which have only been in the
tree for two or more years now), except in a few places where there's
code to be compatible with older versions of FreeBSD.

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.

Add BCTV3/PCI entry.

Rename functions bctv_* to bctv2_* and macros BCTV_* to BCTV2_* for
coexistance of BCTV2 and BCTV3.

Rename CARD_IO_GV to CARD_TO_BCTV2.

Add auto recognition of BCTV3/PCI.

Make PLL mode the default for Bt878s. You no longer need options BKTR_USE_PLL

Split the Bt848 driver into seperate files for
audio, tuner, card make, os dependent code and core bt848/i2c code.

Also, rewrite tuner code for FM Radio to make the code cleaner.
