Subject: Add a script based on the "menagerie-fuzz" buildbot test.  Running
 "./tools/fuzz-test.sh /path/to/capture/files/*" will iterate over the
 specified capture files, using editcap to introduce errors and tethereal to
 check for bugs.  It will do this until tethereal exits abnormally or a
 dissector bug is encountered.
