Also removed the callback functions for the existing regexes. Nothing
has to be or is encoded or escaped at this time, so preg_replace()
can be used instead of preg_replace_callback().

InstallDocFormatter didn't escape the double underscores in
__TOC__. I also noticed that wfEscapeWikiText had a similar
bug, which I reported as bug 53658 (fixed separately).
