[PATCH] docs: page.xsl: Improve generation of paragraph anchor links

[Peter Krempa <pkrempa@xxxxxxxxxx>]

Use the 'parent' axis to check whether the parent is a div with
class='section' rather than looking for 'toc-backref' anchor to see
whether to generate one of the headerlink alternatives. Both hare
docutils-specific thus apply to docs generated from RST documents.

This adds the links for pages generated from RST documents which don't
have a table of contents (and thus lack the 'toc-backref' anchors) and
thus fixes pages such as hacking.html and news.html to have reasonable
links which can be shared.

Note that whether or not to add table of contents to hacking.rst is out
of scope of this patch.
