OVN is separated into its own repo. This commit removes the OVN source,
OVN tests, and OVN documentation. It also removes mentions of OVN from
most documentation. The only place where OVN has been left is in
changelogs/NEWS, since we shouldn't mess with the history of the
project.
There is an exception here. The ovsdb-cluster tests rely on ovn-nbctl
and ovn-sbctl to run. Therefore those ovn utilities, as well as their
dependencies remain in the repo with this commit.

In some of our destructive testing of ovn-dbs inside containers managed
by pacemaker we reached a situation where /var/run/openvswitch had
empty .pid files. The current code does not deal well with them
and pidfile_is_running() returns true in such a case and this confuses
the OCF resource agent.
- Before this change:
Inside a container run:
killall ovsdb-server;
echo -n '' > /var/run/openvswitch/ovnnb_db.pid; echo -n '' > /var/run/openvswitch/ovnsb_db.pid
We will observe that the cluster is unable to ever recover because
it believes the ovn processes to be running when they really aren't and
eventually just fails:
podman container set: ovn-dbs-bundle [192.168.24.1:8787/rhosp15/openstack-ovn-northd:pcmklatest]
ovn-dbs-bundle-0 (ocf::ovn:ovndb-servers): Master controller-0
ovn-dbs-bundle-1 (ocf::ovn:ovndb-servers): Stopped controller-1
ovn-dbs-bundle-2 (ocf::ovn:ovndb-servers): Slave controller-2
Let's make sure pid_exists() returns false when the pid is an empty
string.
- After this change the cluster is able to recover from this state and
correctly start the resource:
podman container set: ovn-dbs-bundle [192.168.24.1:8787/rhosp15/openstack-ovn-northd:pcmklatest]
ovn-dbs-bundle-0 (ocf::ovn:ovndb-servers): Master controller-0
ovn-dbs-bundle-1 (ocf::ovn:ovndb-servers): Slave controller-1
ovn-dbs-bundle-2 (ocf::ovn:ovndb-servers): Slave controller-2

At SUSE12 SP3, we hit a case where ovs-check-dead-ifs tries to read
an entry in /proc/<pid>/fd/<some fd> but hangs forever. The pid is
a qemu-system-x86_64 process and we suspect it's an issue related to
qemu, not ovs. As a result, force-reload-kmod hangs and OVS bridge
never gets restarted. This patch adds a timeout of 5-seconds to
ovs-check-dead-ifs.

Current code of create-cluster from standalone db takes backup of existing
standalone db and then generates a new clustered dbs from backup dbs. Hence,
during migration if nb and sb dbs are still present, create-cluster will fail
saying file exists and will not really convert dbs to clustered dbs. This
patch fixes the same.

We have added code to ovs-save over the last few releases
which makes the following bad assumptions.
1. The default OpenFlow version of running daemon is OpenFlow14.
Impact: This causes upgrades from older OVS versions to end up with no
flows in their bridges (even the default 'NORMAL' ones) causing traffic
to stop.
2. That ovs-ofctl commands like dump-groups and dump-tlv-map
will just work with old OVS versions.
Impact: Does not look like it effects the upgrade in a bad away - except
you get some errors.
Since OpenFlow14 was enabled by default in OVS 2.8, this commit makes
a lazy assumption that any upgrade of OVS from versions before 2.7
will not attempt to save and restore flows.

Sometimes it's unclear which datapath type is in use by particular
bridge. For example, if all the interfaces supported by both system
and netdev datapaths it needs a DB query or log analysis to find out
which 'datapath_type' is in use.
Another case is that it's hard to figure out if patch ports are really
connected to each other. They are definitely not connected if datapath
types of their bridges differs.
With this change non-default 'datapath_type's will be exposed to
'ovs-vsctl show' command, so it'll be easier to spot misconfiguration.

On some systems in case where remote is not responding, socket could
remain in SYN_SENT state for a really long time without errors waiting
for connection. This leads to situations where vconn connection hangs
for a few minutes waiting for connection to the DOWN remote.
For example, this situation emulated by "refuse-connection" vconn
testcase. This leads to test failures because Alarm signal arrives much
faster than ETIMEDOUT from the socket:
./vconn.at:21: ovstest test-vconn refuse-connection tcp
Alarm clock
stderr:
|socket_util|INFO|0:127.0.0.1: listening on port 63812
|poll_loop|DBG|wakeup due to 0-ms timeout
|poll_loop|DBG|wakeup due to 10155-ms timeout
|fatal_signal|WARN|terminating with signal 14 (Alarm clock)
./vconn.at:21: exit code was 142, expected 0
vconn.at:21: 535. tcp vconn - refuse connection (vconn.at:21): FAILED
This patch allowes to specify timeout value for vconn blocking
connections. If the connection takes more time, socket will be closed
with ETIMEDOUT error code. Negative value could be used to wait
infinitely.

As far as RPMs are concerned, system-id.conf file is declared as being
owned by openvswitch.
At the first ovs startup, ovs-ctl creates this file if none exists without
ensuring this.
We end up with an inconsistency:
$ rpm -V openvswitch
.....UG.. c /etc/openvswitch/system-id.conf
Fix this when ovs-ctl is the one who creates the file.
Note: this issue ends up being hidden after a RPM upgrade, since the
openvswitch user is enforced on the whole /etc/openvswitch directory as a
%post operation.

Current ovs-ctl forces to set full hostname in external-ids. In
some situation users may want to set short hostname. For example,
in OpenStack - OVN integration, Neutron uses the host-id provided
by Nova, which is usually short hostname, to set "requested-chassis"
in OVN. The mismatch in hypervisor's external-ids:hostname setting
causes OVN port binding failure. It can be overridden to short name
but a openvswitch restart using ovs-ctl would again set it to full
hostname. This patch ensures in such use cases --no-full-hostname
can be specified to ovs-ctl to set short hostname instead.
