node: don't ignore timeout config option

According to pwydrych in ticket #1258 :

Adding timeout to munin-node.conf has no effect:

    $ grep timeout /etc/opt/munin/munin-node.conf
    timeout 240

    $ sudo /opt/munin/sbin/munin-node

    $ telnet 127.0.0.1 4949
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.
    # munin node at [***]
    Connection closed by foreign host.

    $ egrep 'Peer|timeout' /opt/munin/log/munin/munin-node.log
    2012/09/18-08:48:49 CONNECT TCP Peer: "127.0.0.1:22230" Local: "127.0.0.1:4949"
    2012/09/18-08:49:49 [91860] Node side timeout while processing: '<no command received yet>'

The variable is not passed to Munin::Node::Service->new:

    $ cat -n node/sbin/munin-node
    [...]
        67      my $services = Munin::Node::Service->new(
        68          servicedir => $servicedir,
        69          defuser    => $config->{defuser},
        70          defgroup   => $config->{defgroup},
        71          pidebug    => $PIDEBUG,
        72      );
    [...]

different state files for cron job & as plugin

Changes the default state file to /var/lib/munin-node/plugin-state/nobody/plugin-apt.state so the plugin can report anything of use.

node.d/ntp_states: improve compatibility with older perls

The \R regex sequence was introduced in perl 5.10.0, so this did not
work on CentOS 5's perl 5.8.8. Using \s instead fixes this. Noticed by
leeclemens in pull request #80.

plugins/apt: fix plugin statedir for cron

The apt plugin has its state updated in cron. There the ENV var
MUNIN_PLUGSTATE doesn't exist, so we need to set a default.

Completes d53b34d1bdfafece48e50f2d690b2e1130b6f1dd, to do the same,
but for apt plugin.

html: fix bug introduced by 1aec747c10

Commit 1aec747c10f0d5077842294ca351b918b77fb1e9 failed to address the fix in
789c59e3a27f5d38cabd02c8f57fec605e6146a8 fully. So we somewhat revert
1aec747c10 in stable-2.0.

Yet, as 1aec747c10 is a big performance enhancer, it might be a good idea to
rework on it in devel. But for stable-2.0, the performance hit is acceptable.

Closes: D:689291
graph: remove all extra INFO messages

The start/stop logs are now just plain wrong. Removing them in stable-2.0, as
they are wasting quite a huge diskspace, for almost no value.

And postpone a proper logging scheme for devel.

This isn't strictly a bugfix, but it is low risk as it does only

graph: remote superfluous -T in cmdline

munin-graph runs from cron, so -T is uneeded.

It is even harmful, since -T makes it ignore environnement vars. And
it is the only cron-runned part that uses it, as the code origins as
a fork of munin-cgi-graph.
