Print statistics after sb2 finishes (and/or error+warning messages)

- a new uility, "sb2-monitor", will be started by "sb2" to produce statistics
  and/or error messages after the command started by "sb2" finishes (actually,
  the messages are produced by a new helper script, "sb2-exitreport", which
  gets started by sb2-monitor)
  N.B. sb2-monitor tries to be as transparent as possible, preserving signals
  etc., but that is a somewhat complex task. see the source code for furher
  comments.
- logging level is now "warning" by default (previously the default was
  to keep logging off, and simply loose all errors and warnings)
- added two new sub-commands to sb2-show: "log-error" and "log-warning" can
  be used to add messages to the log. An easy way to test the operation of
  "sb2-monitor" is to run "sb2 sb2-show log-error testmessage", and
  "sb2 -d sb2-show log-error testmessage" for even more details about the run.
- There is also a new test program, signaltester.c, which can be used when
  testing&developing sb2-monitor.
