Subject: [PATCH] data: don't send change updates for login-history

The login-history property of user objects can be quite large.
If wtmp is changed frequently, that can lead to memory fragmentation
in clients.

Furthermore, most clients never check login-history, so it's
wasted memory and wasted cpu.

This commit disables change notification for that property.  If
a client really needs to get updates, they can manually refresh
their cache when appropriate.

         <doc:para>
           The login history for this user.
           Each entry in the array represents a login session. The first two
           members are the login time and logout time, as timestamps (seconds since the epoch). If the session is still running, the logout time
           is 0.

         <doc:para>
           The a{sv} member is a dictionary containing additional information
           about the session. Possible members include 'type' (with values like ':0', 'tty0', 'pts/0' etc).
