The following set of patches further improves network namespace support in
    LNST.

Most of the patch set implements support for veth devices. Since veth devices
    are always created in pairs they're represented a bit differently in the recipe
    XML - by encompasing two <veth> tags within a <veth_pair> tag.

The first patch of the set also takes care of remounting sysfs on namespace
    creation which makes it usable for configuration again.

Example recipe with veth devices:
    <lnstrecipe>
        <network>
            <host id="testmachine1">
                <interfaces>
                    <eth id="out_if" label="tnet"/>
                    <veth_pair>
                        <veth id="testifc1" netns="xyz">
                            <addresses>
                                <address value="192.168.200.2/24"/>
                            </addresses>
                        </veth>
                        <veth id="testifc2"/>
                    </veth_pair>
                    <bridge id="br">
                        <slaves>
                            <slave id="out_if"/>
                            <slave id="testifc2"/>
                        </slaves>
                    </bridge>
                </interfaces>
            </host>

<host id="testmachine2">
                <interfaces>
                    <eth id="testifc2" label="tnet">
                        <addresses>
                            <address value="192.168.200.3/24"/>
                        </addresses>
                    </eth>
                </interfaces>
            </host>
        </network>

<task>
            <run host="testmachine1" module="IcmpPing" netns="xyz">

                    <option name="addr" value="{ip(testmachine2,testifc2)}"/>
