Subject: [PATCH] Fix uninitialized read in rfc1867 handler reported by
 valgrind. Only in PHP 5.6. This commit fixes initialized read, but calling
 php_session_initialize() directly is problematic because configuration could
 be invalid. Invalid config may result in segfault. This will be addressed
 later.
