Add TXT record support for virtual DNS service

Browse Source 
This commit introduces the <dns> element and <txt> record for the
virtual DNS network. The DNS TXT record can be defined using following
syntax in the network XML file:

  <dns>
    <txt name="example" value="example value" />
  </dns>

Also, the Relax-NG scheme has been altered to allow the texts without
spaces only for the name element and some nitpicks about memory
free'ing have been fixed by Laine so therefore I'm adding Laine to the
SOB clause ;-)

Currently supported elements are:

<dd>A <code>dns</code> element can have 0 or more <code>txt</code> elements.
Each txt element defines a DNS TXT record and has two attributes, both
required: a name that can be queried via dns, and a value that will be
returned when that name is queried. names cannot contain embedded spaces
or commas. value is a single string that can contain multiple values
separated by commas. <span class="since">Since 0.9.3</span>
