Standardize SQL PrettyPrinter + Generic DDLs

[apavlo]

1. We should use a prettyprinter for the SQLStmt queries and DDL files. I did this for the TPC-H queries because the old formatting was atrocious. But I was not able to find an online prettyprinter that had the right formatting.

   • There is some old code from H-Store where I use a Java constant for table names. I forget why I did this but we don't need it anymore. Example:

     benchbase/src/main/java/com/oltpbenchmark/benchmarks/tatp/procedures/DeleteCallForwarding.java

     Line 33 in 59a7a7d

     "SELECT s_id FROM " + TATPConstants.TABLENAME_SUBSCRIBER + " WHERE sub_nbr = ?"

   • It would be nice if we could make sure DDL files are formatted correctly automatically.
   • We don't need to worry about dialect files (for now).

2. We need to make sure that the generic DDLs do not use DROP TABLE...CASCADE. This is a minor thing that is not supported in SQLite. We should probably codify the rules of what is the minimum SQL features for these DDL files. @timveil already did the right thing and made it so that MySQL is no longer assumed to be the generic DDL.
