For supporting users it is often useful to send them links to a
certain section in the documentation. The Gerrit documenation contains
a lot of anchors, but they are not easily accessible. If the section
is linked from the TOC the link to the section can be gained by
clicking on the link in the TOC. To link to other elements it is often
needed to check the HTML source code to find out the link target.
Make the links to section headings and anchors easier accessible by
displaying a link icon when the mouse is hovered over the heading or
anchor. By clicking on the link icon the page anchor is set and the
link can be copied from the address bar of the browser.
Having this functionality for anchors is especially useful for linking
to certain configuration parameters in the config-gerrit.html page.
