Generate database schema from database model instead of C++ model

We now first create the so-called database model from C++ model and
then use that to generate the database schema. The new approach also
adds more general support for primary/foreign keys, including multi-
column keys. Finally, for MySQL we now generate out-of-line foreign
key definitions. Because MySQL does not support deferred constraints
checking, deferred foreign keys are written commented out, for
documentation.
