Fixed bug #12154: a query returned: Column <name> cannot be null. The problem was due to a bug in the function setup_table_map: the flag maybe_null was set up incorrectly for inner tables of nested outer joins. join_nested.result, join_nested.test: Added a test case for bug #12154. mysql-test/t/join_nested.test: Added a test case for bug #12154. mysql-test/r/join_nested.result: Added a test case for bug #12154. sql/mysql_priv.h: Fixed bug #12154: a query returned: Column <name> cannot be null.

Added a case for bug #4976 when one of the inner tables is empty. select.result, join.result: Reversed the previous change of the erronious fix for bug #4976. sql_select.cc: The previous fix for bug 4976 was reversed as it erroniously converted an outer join into an innner join when on_expression does not refer to outer tables. This is not valid if inner tables return an empty set. Setting dependency on outer tables was added for the above cases. To fix the crash in the test case of bug #4976 a guard was added that blocks running the crashing code for nested outer joins. sql/sql_select.cc: The previous fix for bug 4976 was reversed as it erroniously converted an outer join into an innner join when on_expression does not refer to outer tables.
