pci support. This really needs to be fixed properly some day, but judging
by the fact that the nopci case hasn't compiled for quite a while, there
does not seem to be much urgency.

This driver actually works slightly better on -stable than on -current
(the system locks on detach on -current), so it should be MFC'd somewhat
sooner.
This driver currently points out a difficulty in the sound device framework.
The PCM unregister routine is allowed to refuse the detach if the device is
in use. In the case of a USB device, however, this unregistration is much more
mandatory in nature, since the device is *actually* gone when this call is
made. The sound subsystem really should not refuse an unregistration and
should take its own steps to reject further I/O. As a result, if you detach
a USB sound device while it is in use, you can expect a panic shortly
thereafter.
This device cannot currently record audio. Some routines are unwritten as
of yet in uaudio.c to support recording.
This device hangs my -current box on detach. I don't know why. This does
not happen on my -stable machine.

xstrdup. There is a crash() function that do cleaning before exiting the
program. The new functions are wrappers that make use of crash() in case
of allocation failure. warn, exit -> err.

shell function and alias lookup. The -p option has been implemented, the
UPE -v and -V options have not. The old `command' command has been renamed
to `builtin'.
data structures pick up security and synchronization primitives, it
becomes increasingly desirable not to arbitrarily export them via
include files to userland, as the userland applications pick up new
#include dependencies.

windows. Right now we only support pci chips that are memory mapped.
These are the most common bridges in use today and will help a large
majority of the users.
I/O mapped PCI chips support this functionality in a different way, as
do some of the ISA bridges (but only when mounted on a motherboard).
These chips are not supported by this change.
but is useful to have handy. EFI GPT partitions are used instead of the
fdisk+disklabel combination. They are pure 64 bit LBA, are fully
extensible, support up to 16383 partitons per disk, etc.
