doc: use reStructuredText for man and HTML pages

The Makefile now requires the rst2html and rst2man programs. Both can
be found in Debian testing or downloaded from the Docutils homepage:

  http://docutils.sf.net/
  http://docutils.sf.net/sandbox/manpage-writer/

The new HTML and man pages no longer contain huge amounts of
un-wrapping literal blocks, thanks to how snippets of reStructuredText
can easily be included inside other reStructuredText documents.

The HTML pages now have anchors for all sections, including the help
topics in hgrc.1 which were missing from the old HTML pages.
