release: Turn manual into serveral chunks.

This allows us to write separate chapters/parts of documentation without
getting one big HTML page with everything at once.

Now the chunk.xsl by default chunks of <preface/> elements, so we'd like
to control this by patching docbook5_xsl directly and prevent it from
doing that.
