a test for the shutdown situation

Here is another small test case.

Output on another free VM looks like this:

jamvm test.shutdownhook.Test
waiting ...
Shutting down!
Exception in thread "Thread-3" java.lang.Error
   at test.shutdownhook.Test$3.run (Test.java:26)
   at java.lang.Thread.run (Thread.java:674)
Exception in thread "Thread-2" java.lang.NullPointerException
   at test.shutdownhook.Test$2.run (Test.java:19)
   at java.lang.Thread.run (Thread.java:674)

On gcj the shutdown hooks are not called when stopping it via ctrl-c.

The Sun JVM does not run shutdown hooks and similar stuff when running with
-Xrs[0].

The signal handler (here called "shutdown()") can't legally be unwound if
::java::lang::System::exit throws an exception.  Studying the libgcj runtime
code, I'm not sure if this might happen.  The Java class lib spec says "This
method never returns normally", suggesting that an exceptional return is possible.
We could simply catch everything in shutdown() and then call exit().  With that
and the removal of ::gcj::reduceSignalUsage this patch would be fine for POSIXy
systems.
