Only the time connected (if connected) or disconnected (if disconnected) is
currently reported for each manager. Change to reporting both in seconds since
the last connect and disconnect events respectively. An empty value indicates
no previous connection or disconnection.
This can help diagnose certain connectivity problems, e.g. flapping.

Bug #4833.
reconnect uses the same connection state names as rconn with the exception of
the above. This commit makes their states identical, which should reduce
confusion for people debugging connection problems.
Commit a4613b01ab (ovsdb: Change the way connection duration time is reported
in Manager table.), pushed earlier today, requires this commit, so OVSDB has
been unbuildable from then to now.
These initial bindings pass a few hundred of the corresponding tests
for C implementations of various bits of the Open vSwitch library API.
The poorest part of them is actually the Python IDL interface in
ovs.db.idl, which has not received enough attention yet. It appears
to work, but it doesn't yet support writes (transactions) and it is
difficult to use. I hope to improve it as it becomes clear what
semantics Python applications actually want from an IDL.
