Subject: r11022:  r10309@SERNOX:  metze | 2005-09-19 11:08:37 +0200  - add
 winsdb_connect() function, so that the winsdb can be opened by the
 wrepl_server/ code  - remove maintaining of a min_version field, as it was
 implemented incorrect, and is maybe not needed at all  - fix handling of
 max_version, (we started with 0, on each server start)
