Is there a reason these arguments are in place, though they dont actually exist as parameters for `LogoutUrlGenerator::getLogoutPath` and `::getLogoutUrl`?
see https://github.com/symfony/symfony/blob/3.4/src/Symfony/Component/Security/Http/Logout/LogoutUrlGenerator.php#L76
and https://github.com/symfony/symfony/blob/3.4/src/Symfony/Component/Security/Http/Logout/LogoutUrlGenerator.php#L88
If there is no reason, this PR can be merged, because this parameter makes no sense there. ;-)

[HttpKernel] Correctly merging cache directives in HttpCache/ResponseCacheStrategy

This PR is a first draft to fix the incorrect merging of private and other cache-related headers that are not meant for the shared cache but the browser (see mentioned issues).
The existing implementation of `HttpFoundation\Response` is very much tailored to the `HttpCache`, for example `isCacheable` returns `false` if the response is `private`, which is not true for a browser cache. That is why my implementation does not longer use much of the response methods. They are however still used by the `HttpCache` and we should keep them as-is. FYI, the `ResponseCacheStrategy` does **not** affect the stored data of `HttpCache` but is only applied to the result of multiple merged subrequests/ESI responses.
I did read up a lot on RFC2616 as a reference. [Section 13.4](https://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html#sec13.4) gives an overall view of when a response MAY be cached. [Section 14.9.1](https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9.1) has more insight into the `Cache-Control` directives.
Here's a summary of the relevant information I applied to the implementation:
- > Unless specifically constrained by a cache-control (section 14.9) directive, a caching system MAY always store a successful response (see section 13.8) as a cache entry, MAY return it without validation if it is fresh, and MAY return it after successful validation.
A response without cache control headers is totally fine, and it's up to the cache (shared or private) to decide what to do with it. That is why the implementation does not longer set `no-cache` if no `Cache-Control` headers are present.
- > A response received with a status code of 200, 203, 206, 300, 301 or 410 MAY be stored […] unless a cache-control directive prohibits caching.
> A response received with any other status code (e.g. status codes 302 and 307) MUST NOT be returned […] unless there are cache-control directives or another header(s) that explicitly allow it.
This is what `ResponseCacheStrategy::isUncacheable` implements to decide whether a response is not cacheable at all. It differs from `Response::isCacheable` which only returns true if there are actual `Cache-Control` headers.
- > [Section 13.2.3](https://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html#sec13.2.3): When a response is generated from a cache entry, the cache MUST include a single Age header field in the response with a value equal to the cache entry's current_age.
That's why the implementation **always** adds the `Age` header. It takes the oldest age of any of the responses as common denominator for the content.
- > [Section 14.9.3](https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9.3): If a response includes an s-maxage directive, then for a shared cache (but not for a private cache), the maximum age specified by this directive overrides the maximum age specified by either the max-age directive or the Expires header.
This effectively means that `max-age`, `s-maxage` and `Expires` must all be kept on the response. My implementation assumes that we can only do that if they exist in **all** of the responses, and then takes the lowest value of any of them. Be aware the implementation might look confusing at first. Due to the fact that the `Age` header might come from another subresponse than the lowest expiration value, the values are stored relative to the current response date and then re-calculated based on the age header.
The Symfony implementation did not and still does not implement the full RFC. As an example, some of the `Cache-Control` headers (like `private` and `no-cache`) MAY actually have a string value, but the implementation only supports boolean. Also, [Custom `Cache-Control` headers](https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9.6) are currently not merged into the final response.
**ToDo/Questions:**
1. [Section 13.5.2](https://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html#sec13.5.2) specifies that we must add a [`Warning 214 Transformation applied`](https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.46) if we modify the response headers.
2. Should we add an `Expires` headers based on `max-age` if none is explicitly set in the responses? This would essentially provide the same information as `max-age` but with support for HTTP/1.0 proxies/clients.
3. I'm not sure about the implemented handling of the `private` directive. The directive is currently only added to the final response if it is present in all of the subresponses. This can effectively result in no cache-control directive, which does not tell a shared cache that the response must not be cached. However, adding a `private` might also tell a browser to actually cache it, even though non of the other responses asked for that.
4. > [Section 14.9.2](https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9.2): The purpose of the `no-store` directive is to prevent the inadvertent release or retention of sensitive information […]. The `no-store` directive applies to the entire message, and MAY be sent either in a response or in a request. If sent in a request, a cache MUST NOT store any part of either this request or any response to it. If sent in a response, a cache MUST NOT store any part of either this response or the request that elicited it.
I have not (yet) validated whether the `HttpCache` implementation respects any of this.
5. As far as I understand, the current implementation of [`ResponseHeaderBag::computeCacheControlValue`](https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpFoundation/ResponseHeaderBag.php#L313) is incorrect. `no-cache` means a response [must not be cached by a shared or private cache](https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9.1), which overrides `private` automatically.
5. The unit tests are still very limited and I want to add plenty more to test and sort-of describe the implementation or assumptions on the RFC.

I am not sure about some translations, if someone could check these, I would appreciate it.
Also, I've found that singular/plural translations have 3 translations. I am not sure if that's a mistake or not. I removed the third translation, but if I was wrong, I'll be happy to put it back.

I used the `mb_ord` to detect whether the amount of bytes read is valid before proceeding. I limit the number of bytes read to 4 before giving up because characters can use at most 4 bytes.
The test passes with or without the fix though.

On any kind of multi loads, including tags loading where it's always the case, current code leads to an explosion of Redis lookups affecting performance on RedisCluster _(as it does not support pipeline)_.
This backports the code for mget() usage from 4.x in order to fix it.
It's done with one small improvment which would also be relevant for 4.x, only using pipeline on cluster on predis as mget is more efficient (ref redis doc).

I ran into an [issue](https://github.com/php-enqueue/enqueue-dev/issues/774) in the enqueue library which copied this part of code from Symfony. I'm now starting to understand what the problem is and it should most likely be fixed in Symfony as well.
I didn't actually run into it in Symfony itself but it seems at least hypothetically possible. Imagine if [here](8c3dc8254a/src/Symfony/Component/HttpKernel/EventListener/ExceptionListener.php (L77)) `$e` is somehow the same (===) as `$exception`. The code [below](https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpKernel/EventListener/ExceptionListener.php#L82-L92) will then find the last exception in the `getPrevious()` chain and assigns `$exception` as the previous. However in the off chance that `$exception` is actually `$e` (the first exception in the chain) then it creates an infinite loop of exceptions which is not good for monolog and exception handlers.
What do you think?

If you have a non-catchable pattern in requirements like f.e. a positive lookahead (.+(?=/foo/)), the generator will not accept the parameter as the parameter itself cannot fulfil the requirement, but only matches in the context of the entire path.
This fix looks for lookAround in the path and ignores checking the requirements if any lookAround exists.
