cvsserver: Checkout correctly on Eclipse

Initial checkouts were failing to create Entries files under Eclipse.
Eclipse was waiting for two non-standard directory-resets to prepare for a new
directory from the server.

This patch is tricky, because the same directory resets tend to confuse other
clients. It's taken a bit of fiddling to get the commandline cvs client and
Eclipse to get a good, clean checkout.
