It should be noted that this changes breaks ABI on 64 bit architectures

of the shminfo structure has changed.

well (in the sense of constructing small patches) for executable code.
Both portsnap (coming to the base system Real Soon Now) and FreeBSD
Update (coming to the base system a bit later) use bspatch.
This is the same code as the bsdiff-4.2 which has been in the ports
tree (misc/bsdiff) for the past year, with the following exceptions:
1. The license is now the traditional 2-clause BSD;
2. Instead of forking and execing bzip2, the code now uses libbz2; and
3. Some minor changes have been made to fit this code into the base
system (adding $FreeBSD$ tags, putting bsdiff and bspatch into separate
directories, etc.)
This code is rather ugly and has lots of style bugs (mostly because I
wrote it before I had ever heard of style(9)). Some day I'll come
back and clean it up.

with a number of positive benefits:
- Start using UMA(9) statistics for mbufs and clusters, which avoids
using the mbuf allocator statistics which suffer from races under
load on SMP. This should eliminate "negative" mbuf counts in
netstat -mb.
- We are now able to track cached (free) mbufs and clusters and count
it towards memory allocated by the network stack.
- We are now also able to track memory allocated to mbuf tags since
libmemstat(3) can also query malloc(9). We don't print this except
as part of the total (for now - #if 0).
- We are now able to track mbuf/cluster/packet allocation failures,
although they are not currently printed (#if 0).
- Don't print out sfbuf statistics when running on a kernel core, as
currently that code is able only to query sysctl for statistics.

1) An unquoted space is always a separator, even when not "in_arg".
2) When a new destination buffer must be allocated during variable
substitution, only copy data from the active buffer to the new
one when we *are* "in_arg".
These were noticed when testing variable-substitution of variables
which have null values, and are not inside quoted strings...
