Doku_Handler::addCall() is not accessible from plugins

addCall() corresponds to former _addCall(). The method visibility has altered to "protected", and now it is not accessible anymore from syntax plugin class.

Some third-party syntax plugins eg. wrap plugin uses _addCall(), and the relevant plugin developers will need to modify their codes so that it will work both with current stable DokuWiki and the Snapshot versions.

It seems that syntax plugins can add any type of call/instruction directly to Doku_Handler::calls array in its handle() method. For example,

   $handler->_addCall('header', [$title,$level,$pos], $pos);

can be rewritten as

      $handler->calls[] = array('header', [$title,$level,$pos], $pos);

I wonder whether this is a practical approach to make one plugin code work well both with "Greebo" and the Snapshot versions?

Well spotted. That's exactly the feedback we need.

I think adding calls is reasonable for plugins so we should make this call public again and have a deprecated tagged legacy method for a while.
