RFR- 7200297 jdwp and hprof code do not handle multiple sun.boot.library.path elements correctly

[BILL PITTORE]

This bug was reviewed by serviceability and hotspot-runtime-dev lists 
since it dealt with jvmti agent code.
  Comments welcome. The intent is to push into tl/jdk tree and then 
eventually back into jdk7u-dev hopefully.  Webrev here:
