Optimized php_controller.c

  * getActionMethods(): operate directly on return_value, do not
    create an intermediate zval
  * getActionPaths(): use zend_hash_quick_find() instead of
    zend_hash_quick_find(): gcc will compute the value of
    zend_inline_hash_func() during compile time
  * use array_init_size() instead of array_init() when the size
    of the array is known in advance
  * use MAKE_STD_ZVAL instead of ALLOC_INIT_ZVAL where the type of
    zval is set explicitly
Use zend_hash_quick_find()
Typo fix
Optimize php_mux.c

  * Use zend_hash_quick_find() instead of zend_hash_find()
  * Use MAKE_STD_ZVAL instead of ALLOC_INIT_ZVAL
  * Use array_init_size() where the size of the array is known
