Andreas Jaeger 2d44b2b36d Prepare for Sphinx 1.5
The new sphinx version introduces some changes that break build:

* Warns if code cannot be parsed for highlighting. Fix the code so
  that it can be parsed, this includes uncommenting "..." lines.
  Note that not every config file is an ini-file.
  Also, the parser seems to have bugs and cannot parse all files.
  Fix mysql ini file and enable the parameter, see
http://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html#sysvar_innodb_file_per_table
* :option: works only with declared options, replace useage with
  simple ``.

This change only handles a few files, more to come later.
