Tests for different drivers will have their own files, but all derive
from a common prototype test series where applicable, similar to the
existing arrangement for database function tests. However, the prototype
will reside with other test cases rather than in the library path. The
database function test series will hopefully be moved as well in time.
This sees the addition of a dateOutFormat parameter to ValueInfo::normalize(), as well as a general simplification of how parameter binding works.
Some value type-casting results are slightly different, but this simply makes SQL statement objects consistent with the rest of the system.
