* Move RowSignature from druid-sql to druid-processing and make use of it. 1) Moved (most of) RowSignature from sql to processing. Left behind the SQL-specific stuff in a RowSignatures utility class. It also picked up some new convenience methods along the way. 2) There were a lot of places in the code where Map<String, ValueType> was used to associate columns with type info. These are now all replaced with RowSignature. 3) QueryToolChest's resultArrayFields method is replaced with resultArraySignature, and it now provides type info. * Fix up extensions. * Various fixes
