ENG-6085: The catalog compilation verifier in VoltCompiler needs to
use the ClassLoader from the jarfile generated in the first pass of
the compiler so that it can find stored procedure and import classes
- Make stored procedures based on inner classes actually work.
- Don't use org.voltdb in the TestVoltCompiler import tests
ENG-6085: Wrap all the catalog manipulation in a try/catch, return
unexpected errors to callers.
