Tree structure for manual pages: crypto(3) links to 33 function

group pages, and these link on to all their second-level subpages.
Only a handful of second-level pages have third-level subpages.
So all crypto pages can now be reached from the www.libressl.org
frontpage via at most four clicks, in most cases three clicks.
Also link back from leaf pages to their respective group pages
and add a couple of additional links between related pages.
Triggered by a question from deraadt@.
