sql.py: When creating a temporary entity (table, function, etc.), instead create it as a permanent entity in debug mode so it can be viewed after the program is run

sql.py: DbConn: Store whether in debug mode (log_debug != log_debug_none) for easy use by methods

bin/map: connect_db(): Turn on autocommit mode in debug mode if commit is on, so that incremental results can be seen in the DB

sql.py: DbConn: Use internal autocommit handling instead of DB connection autocommit attr to avoid autocommits inside a savepoint

sql.py: DbConn: Added autocommit option to turn on autocommit mode. Use set_session() instead of SQL command to set isolation level.

sql.py: mk_insert_select(): embeddable: Fixed bug where the function may do different things when run, because the function (and other statements whose cached strings depend on the function name) may be run after the function definition would have changed, by versioning the function name and using CREATE FUNCTION instead of CREATE OR REPLACE FUNCTION so that its definition never changes

sql.py: Parse "function already exists" errors as DuplicateFunctionException

sql.py: mk_select(): joins: Fixed bug where join_not_equal did not do what it was designed for, which is filtering out matches of the join condition (before the bug fix, it effectively did a cross join with matching rows excluded, causing duplication of rows). Renamed join_not_equal to filter_out to reflect its intended use. Support table-scoped column names in the WHERE conds list.

sql.py: put_table(): Fixed bug where ORDER BY column needed to have table0 name prefixed (if it didn't already have a table name), to avoid ambiguous column references

sql.py: mk_select(): Fixed bug in joins where right_col had the table name prepended before it was copied for use with a different table name in join_using and join_not_equal
