If an Option's normalizer (or lazy default) catches an exception thrown from one of its dependencies, the OptionResolver was left in an inconsistent state which would trigger a false positive cyclic dependency if the throwing option or any of its parent dependencies between it and the catching one are ever called again.

Only merge if #15794 is merged.
If someone explicitly wants to use `stdout`, they can simply pass `$output->getStream()` instead of `$output` in most use-cases.

These shortcut parsers are applied first when converting a CSS selector to XPath, to be faster for simple selectors (tag matching, class matching with an optional tag, id matching with an optional tag).
None of the regexes defined here could have more chances to match more element when backtracking identifiers. So the backtracking is only slowing down the regex engine when the regex does not match (i.e. for any more complex selector for instance, or even for simple selectors without namespace of without tag name). Making quantifiers possessive solves this issue.
I also turned some capturing groups (around the namespace and the namespace delimiter) into non-capturing groups as we don't care about them in the output (they are just here to be optional).

The phpdoc of the interface does not match the behavior of the implementation. And the return type documented by the interface is impossible to return because the interface asks to apply a string prefix, and the only way is to cast the ``XPathExpr`` used internally to a string (which is what the implementation does).
This interface is an internal interface anyway.

I ran Blackfire on the [Mink BrowserKitDriver](https://github.com/minkphp/MinkBrowserKitDriver) testsuite (which is a realistic usage of the Mink API btw, as the driver testsuite is basically a functional test of a fixtures website, where failures are considered to be caused by the driver misbehaving).
I discovered that 17% of the time was spent in ``preg_match_all`` to look for prefixes in the XPath namespace prefixes (Mink does not use any namespace prefix in its Xpath queries).
This optimizes the regex to use a possessive quantifier. This avoids useless backtracking when matching (due to the way the regex is written, backtracking cannot allow finding more matches here). See https://blackfire.io/profiles/compare/21aaebf3-e38f-456a-8fc9-cf7d9e2a35eb/graph for the improvement.
The optimization is applied in the 2.7 branch, because this regex does not exist in 2.3: the registration of namespaces was added in 2.4

Reason: With the whitespaces, there would be a "gap" between `<input>` and `<label>` which is clickable, but doesn't activate the `<input>`.
It's easy to *add* some margin with CSS, whereas it's impossible to *remove* whitespaces with CSS.

[Finder] Optimize the hot-path

A significant part of the perf gain in #15802 was related to filters not being applied recursively...
#15824 fixing this, performance dropped again.
This PR optimizes the hot path by replacing a regexp test by a simple `isset` when possible.
Blackfire diff after #15824 is the following:
https://blackfire.io/profiles/compare/9e489018-998d-4acb-92a0-46011828e83b/graph
`preg_match` is not called anymore, and `Symfony\Component\Finder\Iterator\RecursiveDirectoryIterator::current()` is also cut by two.
When this `isset` optimization is disabled and replaced by a concatenation of all the regexps patterns in a single bigger one, the gain is still significant but lower:
https://blackfire.io/profiles/compare/db86b80e-b63e-4fc9-9ff3-9ed32baeb948/graph
This makes me think that an other and last round of optimization is possible by merging all regexps in one in MultiplePcreFilterIterator filters. If someone wants to work on this, please do it :)

#15802 was broken because the filters where not propagated to children iterators. This fixes the issue and adds a test case for this situation. The RecursiveIterator implementation is moved from FilterIterator to ExcludeDirectoryFilterIterator. Doing so on other filters is possible but would be a new feature that is not required for fixing the performance issue we had previously.
