Fixed bug #898: Problem with xdebug_var_dump'ing empty string keys in ArrayObject.
Merged pull request #37
Merge branch 'xdebug_2_2'
Preliminary support for PHP 5.5 - this still segfaults in places.
Splitting the test case where the PHP 5.5 variant has more information.

Finally, the internally called functions show up again! This was missing since
PHP 5.0.
Add extra checks whether variables have been set.

This solves some crashes, although it produces weird results in PHP 5.5 a
little still.
Macroize opline_ptr as it relies on current_execute_data too, which is different in zend_execute_ex.
Added support for generators.
