Freshness of each extension was been checked everytime a template was loaded.
Projects with many templates and extension benefit noticeably with this cache.
Only environments with debug or autoload set are affected.

Fix custom escaper null values
First, a bit of context:
About 10 years ago, when I was doing some Java, I used to use a SQL mapper called iBatis (now moved to myBatis here: http://mybatis.github.io/mybatis-3/dynamic-sql.html)
The whole concept is to put SQL requests in XML files and use XML as a templating engine. Here is a code sample:
```xml
SELECT * FROM BLOG
WHERE state = ‘ACTIVE’
<if test="title != null">
AND title like #{title}
</if>
```
Fast forward today. I just realized Twig could be a great tool to do exactly the same. Just imagine:
```SQL
SELECT * FROM BLOG
WHERE state = ‘ACTIVE’
{% if title %}
AND title like {{ title }}
{% endif %}
```
All I need to do is write a custom escaper. Like this one:
```php
$twig->getExtension('core')->setEscaper('sql', function(\Twig_Environment $env, $string, $charset) use ($connection) {
// $connection is a DBAL connection
return $connection->quote($string);
});
```
Now, here is my problem:
For an SQL escaper to work, I would need *null* to translate into the 'NULL' string.
But in Twig, escapers are not triggered for null or numeric values. This is due to these lines of code: https://github.com/twigphp/Twig/blob/1.x/lib/Twig/Extension/Core.php#L1021-L1027
```php
if (!is_string($string)) {
if (is_object($string) && method_exists($string, '__toString')) {
$string = (string) $string;
} else {
return $string;
}
}
```
Everything that is not a string (i.e. a numeric value, null, an array...) is directly returned and completely bypasses the escaper.
I understand that this behaviour is ok in most cases (html, js, css, url, etc...), and that it allows some degree of optimisation, but it prevents from working on more specific escapers like a SQL escaper. It is also an undocumented behaviour of custom escapers.
This pull request tries to fix this without impacting performance.
In most Twig installations, no custom escapers are used. In this cases, returning early is a good idea since all default escapers share the same behaviour.
If there is a custom escaper configured however, I'm going the "long" route to be sure that the custom escaper is fed with all values (and not only non empty strings)

Remove deprecated return types from the PHPDocs.
There are deprecation warnings added to the environment (for example https://github.com/twigphp/Twig/blob/1.x/lib/Twig/Environment.php#L1287).
This PR aims to remove the deprecated return types from the PHPDocs as well. It will be useful for developers, but for for IDE's/SCA as well.

Non-existing files are not cached by statcache
Reverts #1583
Based on the docs this cannot happen because the stat cache is only active for existing files.
> You should also note that PHP doesn't cache information about non-existent files. So, if you call file_exists() on a file that doesn't exist, it will return FALSE until you create the file. If you create the file, it will return TRUE even if you then delete the file. However unlink() clears the cache automatically.
http://php.net/manual/en/function.clearstatcache.php
Also the arugments you pass to clearstatcache(false, $filename) make no sense according the documentation and are not effective.
> filename
Clear the realpath and the stat cache for a specific filename only; only used if clear_realpath_cache is TRUE.
Also doctrine cachee does't use this approach either: https://github.com/doctrine/cache/blob/master/lib/Doctrine/Common/Cache/FileCache.php#L185 And nobody reported problems with this as far as I can see.

String-cast in template_from_string
Fixes#1829 caused by https://github.com/twigphp/Twig/pull/1807/files#diff-5e190f538c5c328c7473a5cfd3b7cd95R578
As twig allows many types in twig templates, e.g. array or traversable, we can do the same for string.
But we only take this approach for twig exposed function/filters etc, i.e. template code, but not core code.
