Add support for MySQL mediumint auto increment
Add support for SSL modes in the PG connection string, fix #137.

In passing, refactor the *pgconn- dynamic bindings in favor of directly
using the connection property list straight from the connection string
parser, processing it when necessary. That allows to make it simple to
add an internal :use-ssl property.
Cleanup a double pg-setting setting.

That is now taken care of in the main query macros.
