tdf#116944 Warn user before database migration

Warn user with a pop-up dialog before migration.

To do that we have to know the database URL at UI level. In order to get
that I updated XDataSource interface with getConnectionURL().

The dialog offers two options: proceed with or without migration. If the
user choose "yes", we store that information in XDataSource. The
migration itself will be made in buildLowConnection().
