RFR(M): JDK-8041639: Don't link the java_crw_demo shared library from product tools

[Dmitry Samersoff]

Hi Everybody,

Please review:

http://cr.openjdk.java.net/~dsamersoff/JDK-8041639/webrev.01/

The fix moves code from java_crw_demo to libhprof. Also I remove mtrace
and minst demos that uses java_crw_demo library.
