This patch is a simple implementation for the proposal discussed in
https://mail.openvswitch.org/pipermail/ovs-dev/2017-August/337038.html and
https://mail.openvswitch.org/pipermail/ovs-dev/2017-October/340013.html.
It enables ovs-vswitchd and other utilities to use DNS names when specifying
OpenFlow and OVSDB remotes.
Below are some of the features and limitations of this patch:
- Resolving is asynchornous in daemon context, avoiding blocking main loop;
- Resolving is synchronous in general utility context;
- Both IPv4 and IPv6 are supported;
- The resolving API is thread-safe;
- Depends on the unbound library;
- When multiple ip addresses are returned, only the first one is used;
- /etc/nsswitch.conf isn't respected as unbound library doesn't look at it;
- For async-resolving, caller need to retry later; there is no callback.

Currently, Open vSwitch on linux embeds the logic of loading and unloading
kernel modules into the ovs-ctl and ovs-lib script files. This works, but
it means that there is no way to leverage extended filesystem attributes
to grant fine grain permissions relating to module loading.
The split out utility 'ovs-kmod-ctl' will be used in an upcoming commit
for RHEL-based distributions to have a separate transition domain that
will allow module loading to be given to a separate selinux domain from
the openvswitch_t domain.

GitHub uses a library called Licensee to identify a project's license
type. It shows this information in the status bar and via the API if it
can unambiguously identify the license.
This commit creates a LICENSE file that stores the full text of the
Apache license. It also removes the COPYING file and transfers its
contents to a new "License" section in the README.
Collectively, these changes allow Licensee to successfully identify the
license type of Open vSwitch's codebase as Apache.

The _Server database is valuable primarily because it provides database
clients a way to find out the details of changes to databases, schemas,
etc. in a granular, natural way. Until now, the only way that the server
could notify clients about these kinds of changes was to close the session;
when the client reconnects, it is expected to reassess the server's state.
One way to provide this kind of granular information would be to add
specific JSON-RPC requests to obtain notifications for different kinds of
changes, but since ovsdb-server already provides granular and flexible
notification support for databases, using a database for the purpose is
convenient and avoids duplicating functionality.
Initially this database only reports databases' names and schemas, but
when clustering support is added in a later commit it will also report
important aspects of clustering and cluster status. Thus, this database
also reduces the need to add JSON-RPC calls to retrieve information about
new features.

Currently, on installation or upgrade the openvswitch-switch deb package
will in some circumstances modify a pre-existing
/etc/default/openvswitch-switch configuration file.
This does not play well with modeling and configuration management tools
and may lead to unnecessary restarts of the openvswitch-switch service
after the initial restart done as part of the package upgrade. As
restarting the openvswitch-switch affects the datapath this is
something we should try to avoid.
I also believe the current behaviour to be in conflict with best practices
set out in the config files section of the
[Debian Policy](https://www.debian.org/doc/debian-policy/#s-config-files).
This commit addresses this by removing the part of the postinst script
that attempts to append missing documentation parts of the template
and leaves the installed defaults file alone when it exists.

Presently, logrotate script, searches for the pid files in /var/log/openvswitch
and passes the pid file name (without .pid) as target to ovs-appctl. This approach
doesn't work for OVN DB servers since the ctl files are generated as "ovnnb_db.ctl"
and "ovnsb_db.ctl". So search for the .ctl files instead and use them as target to
ovs-appctl.

Given that it is libopenvswitch-dev not libopenvswitch that depends on
libssl-dev, this patch updates debian/control file to reflect that
libopenvswitch-dev depends on libssl-dev, and libopenvswitch depends
on openssl.

For a while, ubuntu used upstart scripts as an alternative
for sysv scripts. For e.g popular releases like ubuntu12.04
and ubuntu14.04 have upstart infrastructure. From Ubuntu16.04,
they have moved to systemd.
Ubuntu maintainers have a fork of openvswitch packages with
upstart scripts. When a user installs openvswitch-switch
package on a ubuntu 14.04 with 'apt-get install openvswitch-switch',
two upstart files are added to /etc/init directory.
Now, when the same user builds debian packages from this repo
and then installs them, the older upstart files don't get
deleted. What this means is that a command like
'invoke-rc.d openvswitch-switch restart' calls initctl scripts
instead of sysv script that this repo provides. In our sysv
scripts we have logic to carefully upgrade kernel module and
save openflow flows. This breaks the intent of the package from
this repo.
This commit deletes any stale upstart files that have remained
in the system.

The 'openvswitch-common' package did not work well with cross-compiling
since it required Python. This package is broken into two packages as
follows:
- libopenvwitch: contains library files (.a, .so)
- openvswitch-common: depends on libopenvswitch, contains command-line
tools such as ovs-ofctl, ovs-appctl etc.
In addition, this 'openvswitch-dev' library is renamed to
'libopenvswitch-dev' to align more closely with Debian policy. It
depends on libopenvswitch.

Commit 618a5b45ae8b ("rhel: Avoid logrotate error if /var/run/openvswitch
does not exist") updated the RHEL logrotate configuration. This commit
makes similar changes for Debian, by synchronizing with the RHEL version.
In particular:
- Indent to match logrotate.conf(5) examples.
- Use "sharedscripts" flag, because the postrotate script only needs to
run once regardless of the number of rotations.
- Drop "delaycompress", because the postrotate script does make daemons
reopen their log files.
- Ignore errors calling vlog/reopen.
Also make similar changes to the xenserver logrotate script. I confirmed
via Twitter that the xenserver packaging still has users.

Let's start with a simple one that lets us focus on setting up most of
the required "infrastructure" for building man pages using Sphinx.
This changes the 'check-htmldocs' target to 'check-docs' as its now
responsible for building man page docs too.
Other than that, hurrah for (mostly) legible syntaxes.

"make clean" should remove all files generated by building a program, while
"make distclean" should also remove files generated by configuring the
program. Previously some generated files during the build process, such
as man pages, were left behind when "make clean" was run. This commit
only leaves configuration files after "make clean" is run, and removes
all other generated files.

The Debian packages for OVS have only supported Linux so far, but the
ovn-docker package was mistakenly marked as Architecture: any instead
of linux-any, which caused build failures. This fixes the problem.
(Perhaps OVS packaging for Debian should also support BSD, but that
would be a bigger change.)

The debian packages are ready. This patch fixes the
bug #831924 reported at debian bug tracking system.
With this patch, openvswitch-2.6.1 will be upload to
the Debian archive. If we build the packages with
"dpkg-buildpackage --target binary-indep", an error
state arises. debian/rules should be modified so that
the build-indep and binary-indep target generates
the architecture independent packages. If there are
things not be handled properly,let me know.

OVS GRE IPsec tunnel support has multiple issues, Therefore
it was deprecated in OVS 2.6.
Following patch removes support for GRE IPsec and allows external
IPsec tunnel management for any type of tunnel not just GRE.
e.g. user can encrypt Geneve or VxLan traffic.
It can be done by using openflow pipeline to set skb-mark
and using IPsec keying daemons to implement IPsec tunnels.
This packet can be matched for the skb-mark to encrypt
selective tunnel traffic.

If ipsec_gre tunnel configuration is changed in OVSDB,
then GRE packets may sometimes exit unencrypted until
per-tunnel IPsec policies are installed by ovs-monitor-ipsec
daemon.
This patch fixes this issue by installing single, low
priority IPsec block policy that drops all GRE packets
coming out from ipsec_gre tunnels that do not have yet
their own IPsec policies installed.
This patch depends on to two other recently committed
patches:
1. 574ff4aa (tunneling: get skb marking to work
properly with tunnels)
2. ca3574d5 (IPsec: refactor out some code in
OVS_MONITOR_IPSEC_START macro)
