Checks for duplicate anchors in a file.
For internal references, it checks if anchors exist in current document.
For external references to local files:
- checks if the file exist.
- in case the reference point to an anchor, checks if that anchor exists.
For hyperlinks, check if the target is reachable.

Anchors:
- standard anchors: [[anchor]] and [[anchor, description]]
- bibliography anchors: * [[[anchor]]] or * [[[anchor, description]]]
- inline anchors: [#anchorname] and anchor:anchorname[description]
References:
- Internal references: <<anchorname>> or <<anchorname, description>>
- External references to .adoc files:
  - <<path/to/file.adoc>>, <<path/to/file.adoc#section>>, <<path/to/file#section>> or with an additional description (e.g. <<path/to/file.adoc, description>>)
  - xref:path/to/file.adoc[description]
- External references to other types of files: link:path/to/file[description]
- Hyperlinks using the link: macro (e.g. link:URI[description]) or without: http://www.google.com
