Subject: [PATCH] Support for .execute method at Connection level

Prepared statements can be expensive or unavailable for some
drivers, so Connection.do can skip 'prepare' when no @params given
and the driver support direct execution implementing the .execute
method in its Connection class.
MySQL in particular can't prepare some kinds of statements.
