The function tpl_getFavicon() was doing more than its name was implying. Therefore the new tpl_getMediaFile() was introduced (which is doing nearly exactly the same) and tpl_getFavicon() was deprecated.
tpl_favicon() can still be used, though.

This is in preparation for the new default template. This also updates the tpl_actiondropdown() to use most of them.

Template authors need to update their _mediamanager.css

This could happen if a sidebar is rendered before the page (populating
$TOC) and the page itself had no own TOC (no headers).

show accesskey also on actionlink title and add accesskey parameter only if a key is defined (FS#2226)
