And produce proper docerrors (as opposed to warnings in HTMLWriter). Fix #2130.
This needed quite a bit of refactoring to move the link checking logic from HTMLWriter to CrossReferences. CrossReferences now replaces the local links & images it finds with
PageLink
/LocalLink
/LocalImage
elements that the writers then should be able to safely use to generate the correct hyperlinks.I did notice that local link handling appears to be somewhat broken in LaTeXWriter. In some cases it seems to generate a link ID that probably doesn't exists (from the fragment), and in other cases the links just point to the
.md
file. Not quite sure what to do here, and I'm inclined to leave the implementation broken for the time being.
