The revision argument should be a checkout parameter. open() is talking
about creating a session, and I don't think REV has a place there.

I would agree that SVN_INVALID_REVNUM would meant "latest". I'd also think
creating SVN_LATEST_REVNUM would be fine.

The RA interface could also grow a new query functions: get_revnum_by_date.
We don't have tags, so there isn't a need for revnum_by_name or somesuch.
The interface already has get_latest_revnum; not exactly sure where that
will play, but it can be left for now.
