Use the correct cssselect library name in docblocks.

The original python library is called cssselect, not cssselector.
Update the note about origins of the CssSelector component.

The last rewrite is based on the cssselect which is no longer part of lxml, but was extracted as an independent library.

As suggested in #11894, the original python library is called [cssselect](https://github.com/SimonSapin/cssselect), not cssselector.

I also updated the README, as the cssselect was extracted as an independent library and it's no longer part of lxml.

I have this error ContextErrorException: Warning: inet_pton(): Unrecognized address X.X.X.X:X
in IpUtils.php line 110

X.X.X.X:X is detected as a ipv6 because HTTP_X_FORWARDED_FOR have a port.

[HttpFoundation] fixed error when an IP in the X-Forwarded-For HTTP head...

On symfony.com, we have errors related to IP addresses in the `X-Forwarded-For` HTTP header that have a port. If that happens (I have no ideas what is doing that), the page crashes with an error like `inet_pton(): Unrecognized address 187.65.229.211:63479` (which comes from IpUtils::checkIpv6()). This fixes the root cause by removing the port.

#12572 is solving the consequence and I propose to also merge it.

The default escaping strategy was set on the Twig Engine and not the Twig Environment. That's a problem under some circumstances (like what #11773 describes), but it's also much better to set everything on the Twig  Environment directly.

By default, phpunit preserves global state for isolated processes. This made the tests break on my laptop.
Other tweaks included.
In branch 2.5, `src/Symfony/Component/Security/Csrf/Tests/TokenStorage/NativeSessionTokenStorageTest.php` also misses the `@preserveGlobalState disabled` annotation. Please add it when merging
