This avoids a race in durable handle reconnects if the reconnect comes
in while the old session is still in the tear-down phase.
The new session is supposed to rendezvous with and wait for destruction
of the old session, which is internally implemented with
dbwrap_watch_send() on the old session record.
If the old session deletes the session record before calling
file_close_user() which marks all file handles as disconnected, the
durable handle reconnect in the new session will fail as the records are
not yet marked as disconnected which is a prerequisite.

The initial idea was to have some "atomicity" in this API. Every
caller interested in a record would have to do something with
it once it changes. However, only one caller really used this
feature, and that is easily changed to not use it. So
remove the complexity.

Typicall, when we watch a record, we wait for a process to give up some
resource. Be it an oplock, a share mode or the g_lock. If everything goes well,
the blocker sends us a message. If the blocker dies hard, we want to also be
informed immediately.
