marked some classes as being final
Not sure about this one. I'd like some reviews before merging (we might make some other ones final and I might have marked some as final which should not). ping @stof @nicolas-grekas

Bugfix: When rendering blocks of other templates, don't pass the local blocks array
This PR fixessymfony/symfony#20556.
When referring to a block of another template from within a template that also has a block with the same name, Twig renders the wrong block.

Add support for PHP 7 null coalescing operator
This is just one case where we can "optimize" the ternary operator. PHP 7 also supports more complex expressions that can return `null`. The rule here seems to be that you cannot have more than one level of undefinedness.
So, for instance, if `log` is defined, `log("foo") ?? "NOPE"` works, but `log($a["foo"]) ?? "NOPE"` does not if `$a["foo"]` is not defined. If we want to convert the code to always use `??` when possible, this should probably be implemented in the Optimizer node visitor, not here. But the question is: is it worth it in terms of performance? It cleans up the generated code quite a bit though.
closes#1979

Expose a way to access template data and methods in a portable way
`Twig_Template` is an internal class, and most of its methods are marked as being `@internal` as they are not "safe" to use by end users.
But some of its features are interesting like `renderBlock()` which is very useful when rendering emails for instance (see #1873).
This PR tries to address both issues by marking the whole `Twig_Template` class as being internal and by exposing a new way to safely interact with a template besides the obvious `render()`/`display()` methods via `$twig->load("...")`.
If also add some convenient methods like `hasBlock()` or `getBlocks()` (see ~#1831~ and #1882):
```php
$template = $twig->load('index');
echo $template->render($context);
$template->display($context);
if ($template->hasBlock('name') {
$template->displayBlock('name', $context);
}
foreach ($template->getBlocks() as $block) {
echo $template->render($block, $context);
}
```

Remove optimization as it's not compatible with Symfony cache system
fixes#2243
@nicolas-grekas Instead of fixing Symfony cache system (which will only happen in a new patch release), I propose to revert these changes. It means no optimization for Twig 1.x, but the optimization is the default in Twig 2.0. So, I don't think this is a big deal.
