Fix crash in ha_calpont_impl_close_connection()

    Fix leak in ci.tableMap.

    Removed extra returns in pushdown_init to avoid crashes.

    create_select_handler now detects INSERT..SELECT.

    buildConstColFromFilter now uses any kind of filter to supply
    relevant columns.

    Remove strings used by vtable redo phase.

    Make FromSubQuery aware of Pushdown handlers.

    Changed debug_walk to work around changed Item framework.

    Temporary disabled derived handler and unsupported features checks.
