RFR(S): JDK-8059038 Create new launcher for SA tools

[Dmitry Samersoff]

Hi Everybody,

Please review the changes:

http://cr.openjdk.java.net/~dsamersoff/JDK-8059038/webrev.04/

I'm about to file CCC request for it but would like to get internal
feedback before that.

This fix is introducing native launcher jhsdb for serviceability agent.

jhsdb

will launch command line debugger clhsdb

jhsdb jstack file core
jhsdb jmap file core
jhsdb jinfo file core

will launch corresponding SA based utility.


-Dmitry
