5ca1ba484b openvswitch: Remove Linux bridge compatibility.
Currently brcompat does not work on master due to recent
datapath changes. We have decided to remove it as it is
not used very widely.

acf6085512 ofproto-dpif: Use a single underlying datapath across multiple bridges.
This commit switches to using a single backing datapath (called
"ovs-datapath") for all bridges of that datapath's type.  Previously,
resources couldn't be shared across bridges, since each was in its own
datapath.  This change will allow sharing of tunnels and cheaper patch
ports to be added in the future.

Since bridges share a common datapath, the ovs-dpctl commands won't
provide bridge-specific information.  Users wishing to have that
information should use the new "ovs-appctl dpif/*" commands as
documented in ovs-vswitchd(8).

5aa7547411 docs: Add references to the database schema documentation.
I field lots of questions about "where's the documentation?"  Perhaps this
will help.

The changes to ovs-vsctl(8) add a couple of references to
ovs-vswitchd.conf.db(5) but they also rephrase a couple of paragraphs in
what seems to me an easier to understand style.
