Mode for opening sessions.
This replaces three booleans that were passed in order: ignore_lock, create,
and force. It's structured so that one can use it as a bit field with the
values in the same order, i.e. ignore_lock = 1 << 2, create_new = 1 << 1, and
force_new = 1.
enumeration members
-------------------
SESSION_NORMAL_OPEN = 0 (All False)
Open will fail if the URI doesn't exist or is locked.
SESSION_NEW_STORE = 2 (False, True, False (create))
Create a new store at the URI. It will fail if the store already exists and is found to contain data that would be overwritten.
SESSION_NEW_OVERWRITE = 3 (False, True, True (create | force))
Create a new store at the URI even if a store already exists there.
SESSION_READ_ONLY = 4, (True, False, False (ignore_lock))
Open the session read-only, ignoring any existing lock and not creating one if the URI isn't locked.
SESSION_BREAK_LOCK = 5 (True, False, True (ignore_lock | force))
Open the session, taking over any existing lock.
