It's always been OVS coding style to use spaces rather than tabs for
indentation, but some tabs have snuck in over time. This commit converts
them to spaces.

This patch prepends 'www' to openvswitch urls in index.rst. Without this
make check-docs fails when verifying url liveness. Also remove url
referencing ovsdb-server(5) as these are no longer accessible.

A reader reported that "network database system" made it sound like OVSDB
was specialized for databases about networks. It's not, it's just
accessible over the network.

This commit adds support for OVSDB clustering via Raft. Please read
ovsdb(7) for information on how to set up a clustered database. It is
simple and boils down to running "ovsdb-tool create-cluster" on one server
and "ovsdb-tool join-cluster" on each of the others and then starting
ovsdb-server in the usual way on all of them.
One you have a clustered database, you configure ovn-controller and
ovn-northd to use it by pointing them to all of the servers, e.g. where
previously you might have said "tcp:1.2.3.4" was the database server,
now you say that it is "tcp:1.2.3.4,tcp:5.6.7.8,tcp:9.10.11.12".
This also adds support for database clustering to ovs-sandbox.

With this change, "ovsdb-client convert" can be used to convert a database
from one schema to another without taking the database offline.
This can be useful to minimize downtime for a database during a software
upgrade.

The _Server database recently added to ovsdb-server can be used to dump out
information about databases, but monitoring updates to _Server is not yet
very useful because for historical reasons ovsdb-server drops all of its
OVSDB connections whenever databases are added or removed or otherwise
change in some major way. It is not a good idea to change this behavior
for all clients, because some of them rely on it, but this commit
introduces a new RPC that allows clients that understand _Server to
suppress the connection-closing behavior.

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.

It's becoming more common that OSes include "ip" but not "ifconfig", so
it's best to avoid using the latter. This commit removes most references
to "ifconfig" and replaces them by "ip". It also adds a build-time check
to make it harder to introduce new uses of "ifconfig".
There are important differences between "ifconfig" and "ip":
- An "ifconfig" command that sets an IP address also brings the interface
up, but a similar "ip addr add" command does not, so it is often necessary
(or at least precautionary) to add an "ip link set <dev> up" command.
- "ifconfig" can infer a netmask from an IP adddress, but "ip" always
assumes /32 if none is given.
- "ifconfig" with address 0.0.0.0 removes any configured IP address, but
"ip addr add" does not, so "ifconfig <dev> 0.0.0.0" must be replaced by
"ip addr del" or "ip addr flush".

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.

There is still plenty of opportunity for improvement, but this new
ovs-fields(7) manpage is much more comprehensive than ovs-ofctl(8)
could be.

This is a simple table with links to the manpages published on
openvswitch.org. Something fancier can be done in the future.

Create a series of sections, all of which are currently empty, using
the general design established by Jacob Kaplan-Moss and the Django
project [1]. Five sections are provided:
- intro
- tutorials
- topics
- howto
- ref
- faq
- internals
The purpose of each section is described in the documents themselves.
