Rework special link parsing in the post-processing of markup (#3354)

Browse source 
* Get rid of autolink

* autolink in markdown

* Replace email addresses with mailto links

* better handling of links

* Remove autolink.js from footer

* Refactor entire html.go

* fix some bugs

* Make tests green, move what we can to html_internal_test, various other changes to processor logic

* Make markdown tests work again

This is just a description to allow me to force push in order to restart
the drone build.

* Fix failing markdown tests in routers/api/v1/misc

* Add license headers, log errors, future-proof <body>

* fix formatting
