overlays and config parsing

["Pierangelo Masarati" <ando@sys-net.it>]

In some cases, it may be useful that overlays see configuration directives
__before__ the database, to allow intercepting and overriding them. 
Directives ignored by the overlays would get to the database anyway; the
specific overlay may allow the directive to eventually get to the
database, maybe changed as appropriate.

Comments?
