RFR(M): 7165259 Remove BugSpot

[Staffan Larsen]

Please review the following change to remove the BugSpot UI for the Serviceability Agent. My understanding is that BugSpot was intended as a more general native debugger not only focused on the JVM, but that it was never fully implemented. I don't think there is a need for a general-purpose debugger in SA and would like to clean up the code. One effect of this change is that PStack and PMap will no longer be able to operate on executables other than the JVM.

This change was first proposed last year in this thread: http://mail.openjdk.java.net/pipermail/serviceability-dev/2012-April/005811.html

This change also removes some old JVMDI code in SA (JVMDI is no longer supported in HotSpot).
