number of dma overruns/underruns for systems under heavy dma load.
As a side effect, broken enhanced floppy controllers that sometimes
don't detect dma overruns/underruns will give less errors.

Sorted some declarations.
Fixed missing __P(())'s.
Removed `timeout_func_t (pointer to timeout function) typedef. It was
mainly used in bogus casts. The more useful `timeout_t' (timeout function)
typedef should be used instead.
Cleaned up callout declarations and comments.
extern in <sys/malloc.h> and it should not have been staticized for
the !(KMEMSTATS || DIAGNOSTIC) case.
Fixed the !(KMEMSTATS || DIAGNOSTIC) case. The MALLOC() and FREE()
macros are evil, but code generally doesn't allow for this and some code
involving else clauses did not compile.
Finished staticization.
or a partition is larger than the slice.
Now `disklabel -Brw sdX auto' should fail properly on sliced disks
without partition of type 165, e.g., on zip disks with the factory
default formatting. Previously it set a bogus in-core label for
the compatibility slice and used this to corrupt the MBR (the slice
has offset 0 and size 0, but setting the label in effect corrupted
its size to nonzero).
`disklabel -Brw sdX auto' already failed properly on normally (not
dangerously dedicated) sliced disks _with_ partition of type 165,
because the compatibility slice has a nonzero offset so the MBR
remained inaccessible when the size was corrupted.
This bug only affected in-core labels. On-disk labels are checked
carefully when they read and written.
Hide the bogus FDC ``chip type'' display behind a (mostly) undocumented
option, since people started to trust the bogus claim. Once we're going
to handle 2.88 MB controllers, we have to redo the chip detection, by
now just leave it hidden.

you recompiled libc one of the last couple of days):

We aren't sure if this new code and the old sound code will co-exist in a
kernel, so the device pcm0 line is left commented out in LINT.

While i was at it, also fixed a broken return value for the VT_RELDISP
ioctl, iff the third arg was legally VT_TRUE, but the destination
screen was in process mode so the actual switch had to be deferred.
This was breaking the ability to directly toggle between two X servers
running on two VTs, since the server getting the bogus error return
was running wild, and competing with the other one for the hardware.
(Sigh, this was a very long-standing bug.)

detail is passed back and forwards). This mostly came from NetBSD, except
that our interfaces have changed a lot and this funciton is in a different
part of the kernel.
