must be in the correct order; fixed.

Rev 20 of the tarball has no new function, it is just slimmed down.
I replaced our large statically linked binaries with dynamically linked ones.
Also found and stripped a couple of other binaries.

The resulting tarball goes from 5.7MB to 0.9MB.

The Makefile changes are to incorporate the NOSTATIC=1 environment hack
to enable building the dynamic binaries above.

only works for FC4 (not RHL7 or RHL9) because that function only exists in
the libpcap on FC.  Fortunately, I don't think RHL7 and RHL9 exhibit the
problem in the first place.

Add pcapper.noevents target to Makefile to build without event system

Event system:

When compiled with -DEVENTSYS, can be made to wait for time to start
in an experiment before starting to count packets. Times are also
reported relative to experiment time start. Use the '-e' flag to
enable.

SUID support:

If compiled with -DDROPROOT, and it seems that pcapper was started
setuid root (euid == 0, and ruid != 0), drops root permissions after
opening BPF (or raw socket in Linux.) This allows it get permissions
to read packets, but still be killed by the user. This is particularly
useful with the testbed's program objects.

New command-line options:

-s: Print out packet counts to stdout, in addition to listening
        on a socket ('-f -' does the same thing, too)
-p: Count only payload sizes, not header sizes
-e: Wait for event system time to start in pid/eid
-z: Don't count zero-length packets in the packet counts (useful
        with '-p')

Also, now creates a GNUmakefile the _right_ way.
