Update Python 3 compatibility
When running the server on Python 3, get rid of a few deprecation
warnings.
* mandos (main): Use only "configparser.Configparser", and only fall
back to configparser.SafeConfigParser on Python
versions lower than 3.2. Also, only call
GLib.threads_init() when using a PyGObject version
lower than 3.10.2.

<para>
72
The file &CONFPATH; is a configuration file for <citerefentry
73
><refentrytitle>mandos</refentrytitle>
74
<manvolnum>8</manvolnum></citerefentry>, read by it at startup.
75
The file needs to list all clients that should be able to use
76
the service. The settings in this file can be overridden by
77
runtime changes to the server, which it saves across restarts.
78
(See the section called <quote>PERSISTENT STATE</quote> in
79
<citerefentry><refentrytitle>mandos</refentrytitle><manvolnum
80
>8</manvolnum></citerefentry>.) However, any <emphasis
81
>changes</emphasis> to this file (including adding and removing
82
clients) will, at startup, override changes done during runtime.

The format starts with a <literal>[<replaceable>section
86
header</replaceable>]</literal> which is either
87
<literal>[DEFAULT]</literal> or <literal>[<replaceable>client
88
name</replaceable>]</literal>. The <replaceable>client
89
name</replaceable> can be anything, and is not tied to a host
90
name. Following the section header is any number of
91
<quote><varname><replaceable>option</replaceable
92
></varname>=<replaceable>value</replaceable></quote> entries,
93
with continuations in the style of RFC 822. <quote><varname
94
><replaceable>option</replaceable></varname>: <replaceable
95
>value</replaceable></quote> is also accepted. Note that
96
leading whitespace is removed from values. Values can contain
97
format strings which refer to other values in the same section,
98
or values in the <quote>DEFAULT</quote> section (see <xref

This option overrides the default shell command that the
178
server will use to check if the client is still up. Any
179
output of the command will be ignored, only the exit code
180
is checked: If the exit code of the command is zero, the
181
client is considered up. The command will be run using
182
<quote><command><filename>/bin/sh</filename>
183
<option>-c</option></command></quote>, so
184
<varname>PATH</varname> will be searched. The default
185
value for the checker command is <quote><literal
186
><command>fping</command> <option>-q</option> <option
187
>--</option> %%(host)s</literal></quote>. Note that
188
<command>mandos-keygen</command>, when generating output
189
to be inserted into this file, normally looks for an SSH
190
server on the Mandos client, and, if it finds one, outputs
191
a <option>checker</option> option to check for the
192
client’s SSH key fingerprint – this is more secure against
193
spoofing.

Extended timeout is an added timeout that is given once
212
after a password has been sent successfully to a client.
213
The timeout is by default longer than the normal timeout,
214
and is used for handling the extra long downtime while a
215
machine is booting up. Time to take into consideration
216
when changing this value is file system checks and quota
217
checks. The default value is 15 minutes.

337
The program <citerefentry><refentrytitle><command

Note: this value of this option will probably be very
