Subject: [PATCH] docs: break longer text into paragraphs in HTML

Libvirt's HTML documentation is not as easy to the eyes as it could
be since long text has no visual breaks.

Take advantage of the formatting in documentation comments and wrap
each part separated by two consecutive \n into a HTML <p> element.
