Log Message:
implemented DROP ARRAY and fix bugs in CREATE ARRAY
- in functions that dup/copy tables/columns, we should also dup/copy the new
fields of sql_table and sql_column that were introduced for arrays,
- replaced many (but not all) isTable with isTableOrArray to reuse code, e.g.,
also deal with arrays during processing of transactions
- an example where isTable must not be replace by isTableOrArray is: since we
now only have persistent arrays, the code that does something with temp tables
should not include arrays.
