ifstat Display the network traffic going through active interfaces
on the system. Idle interfaces will not be displayed until
they receive some traffic.
For each interface being displayed, the current, peak and
total statistics are displayed for incoming and outgoing
traffic. By default, the ifstat display will automatically
scale the units being used so that they are in a human-read-
able format. The scaling units used for the current and peak
traffic columns can be altered by the scale command.

"The unifdef utility exits 0 if the output is an exact copy of the input,
1 if not, and 2 if in trouble."
This causes an 'Error code 1 (ignored)' in the world output, which upsets
the whereintheworld scripts that the tinderboxes use.
However, this stuff here is a relic. We do not enable HAVE_TCL_INTERP
nor HAVE_PERL_INTERP.. The Makefile hooks to turn them on have gone ages
ago, and this stuff was here for release building purposes only. Rather
than fight with the tinderbox builds, clean house a bit and remove the
last remaining unused relics of this stuff.
* The partial-evaluation of #elif sequences was broken and the
spaghetti logic of its implementation was too hard to understand.
I've re-done it using a straight-forward table-driven push-down
automaton.
* The pre-processor line parser did not allow for all of the weird
places that people might put comments, which could have caused it
to add syntax-errors to the output by removing a #if line containing
the start- or end-marker of a comment.
* The lexer didn't need to special-case the handling of string-literals
or character-constants, but it did need to learn about line-continuations
(backslash-newline).
* The input routine was buggy and bit-rotten and trivially replacable
with fgets(). I've also made the program static- and const-safe and
improved the presentation-order. The formatting of the state-transition
tables remains non-stylish.

MFC-after: one-week
from "unix" back to "local". Add some compat stuff so both
ways work for some time.
