Hook ubt and ubtbcmfw back up to the build.

Hook up new USB modules.

Disconnect drivers that haven't been ported to MPSAFE TTY yet.

As clearly mentioned on the mailing lists, there is a list of drivers
that have not been ported to the MPSAFE TTY layer yet. Remove them from
the kernel configuration files. This means people can now still use
these drivers if they explicitly put them in their kernel configuration
file, which is good.

People should keep in mind that after August 10, these drivers will not
work anymore. Even though owners of the hardware are capable of getting
these drivers working again, I will see if I can at least get them to a
compilable state (if time permits).

No need to generate vnode_if.h anymore

Build usbdevs.h

Move to generating pccarddevs.h on the fly, both for the kernel and
the modules.

Also generate usbdevs.h automatically now, but a non-kernel file is
stopping that at the moment.

bsd.kmod.mk does not deal with manpages anymore.

Fix make buildkernel.

These makefiles work when building in the sys/modules directory, but
not with the objdir stuff that buildkernel uses. This is because they
used -I../../../blah rather than -I${.CURDIR}/../../../blah.

# I didn't fix the abuse of CFLAGS to specify -g since I wanted the
# barest minimal change since we're in a code freeze.

Hat for armchair anarchists: core member fixing src tree damage

The second try a committing the bluetooth code
Has been seen to work on several cards and communicating with
several mobile phones to use them as modems etc.

We are still talking with 3com to try get them to allow us to include
the firmware for their pccard in the driver but the driver is here..
In the mean time
it can be downloaded from the 3com website and loaded using the utility
bt3cfw(8) (supplied) (instructions in the man page)
