JDK-6346964 - Support dynamic enabling of extended DTrace probes
Description
With 6346964, support dynamic enabling of the extended DTrace Java probes (such as method-entry, object-alloc) is possible. While 6346964 covers changes to JVM to enable dynamic turning on/off of ExtendedDTraceProbes flag, this rfe is to track DTrace-to-JVM interface through a shared object. DTrace will use the shared object interface to turn on/off ExtendedDTraceProbes (or fine-grained variants of it).

EVALUATION We are providing libjvm_dtrace.so and interface header so that DTrace can "tell" JVM to turn on extended DTrace hotspot probes.
