swapctl functionality. The idea is to create a swapctl command that is
fairly close to the OpenBSD and NetBSD version. FreeBSD does not implement
swap priority (and it would be a mistake if we did) so we didn't bother with
that part of it.

bandwidth for other processes. Since the sleeping is done from
userland, this avoids the locking issues that affected the kernel
version.
The algorithm used here is to measure a moving average of the times
taken by a sample of read operations and then delay 1 in 8 reads
by 16 times the measured average. This should correspond to a factor
of 3 slowdown, but in practice the factor is larger (3.5 to 4) due
to hz rounding effects.

live filesystem. To obtain a consistent dump image, dump takes
a snapshot of the filesystem and then does a dump of the snapshot.
The snapshot is removed when the dump is complete.
Also add an operator warning that the `L' option should be used
if dump is run on a live filesystem without the `L' option being
specified. The alternative would be to silently use a snapshot
any time that a live filesystem is dumped, but this change in
dump semantics seemed too drastic at this time.

only preallocates a small number of inodes. The dump program tries
to scan through all the allocated inodes on a filesystem which
causes bad behavior if they have never been allocated. Thus dump
must calculate the set of inodes that have actually been allocated
and scan only those inodes.

partitions to Vinum and was broken by recent more stringent overlap
checks. This is arguably the wrong way to do it. A better method
would be to have the loader understand a subset of Vinum partitioning
and allow an install directly to Vinum, but until then, this is the
best we have.

o When parsing the MBR, explicitly check for a PMBR and create
a PMBR map node if one is found.
o When parsing the MBR, recurse to handle extended partitions.
This allows us to flatten nested MBRs when migrating to a

o Have the migrate command bail out if it encounters a partition
