Fixed as per Tim's comments on r61179:
* made insertOneRow and getSequenceData private
* renamed fieldInfo to fieldInfoMulti and made it private (for internal use on Oracle only)
* wrapped fieldInfoMulti in fieldInfo with error if $table parameter is an array
* reverted tableName function to only support a non-array parameter
* wrapped all tableName calls with array parameter with array_map with callback
* wrapped fieldInfo into textFieldSize function to avoid reimplementation of functionality
* fixed unnessesary multiple calls to tableName with same parameter inside a single procedure
