Title: Do not allow to override superglobals in views

* Do not allow to override superglobals in views;
* Use `zend_hash_merge_ex()` instead of manual iteration over the array and `phalcon_set_symbol()`
* Get rid of the memory frame in `Phalcon\Mvc\View\Engine\Php::render()`
* Make `Phalcon\Mvc\View\Engine::render()` return boolean
* Optimize `Phalcon\Mvc\View\Engine\Volt::length()`
* Optimize `Phalcon\Mvc\View\Engine\Volt::isIncluded()`
