This is a follow up PR to https://github.com/symfony/symfony/pull/20327.
I also decided to improve the current `is_numeric()` check that is done by a truer one. The current limitation is that a PCRE subpattern name must not start with a digit which is different.

As explained in #6775, this has been done for the following reasons:
1. It's also Request::getHost()
2. The term hostname has been obsoleted in
http://tools.ietf.org/html/rfc3986#appendix-D.2 and uses the host only
3. hostname in the RFC was defined as the registered domain name, but we
probably also want to match IP-Adresses with the pattern which is the
host = IP-literal / IPv4address / reg-name for.
This PR was merged into the master branch.

In #5989, it has unanimously been decided to renamed `hostname_pattern` to `hostname` and `pattern` to `path`. That makes a lot of sense and I would like to do the renaming now as `hostname_pattern` is new in Symfony 2.2, so I'd like to avoid breaking BC just after the release. As we are modifying the route options, I've also included changes introduced by @Tobion in #6049 which were discussed in #5990.
As everything is BC, I think it's wise to include that in 2.2. What do you think?

I agree it should be done in 2.2. Thanks for working on it.

@fabpot "Everything is BC" until it breaks BC in 3.0, that's why I'd like to see [deprecations in PR summary](https://github.com/symfony/symfony-docs/pull/2116) what do you think ?
---------------------------------------------------------------------------
by vicb at 2013-01-14T23:16:40Z
it would also be great to update the CHANGELOG with deprecations (it could also help people answering your question)
---------------------------------------------------------------------------

@vicb: I've just updated the CHANGELOG and created the UPGRADE file for 3.0.

@fabpot thanks.
My benchmarks showed a performance improvement of 20% when matching routes that make use of possesive quantifiers because it prevents backtracking when it's not needed

[Routing] compile check for numeric named variables in pattern
Because PHP raises an error for such subpatterns in PCRE and thus would break matching, e.g. this is not allowed as regex `(?<123>.+)`.
So add a compile time check for a non-working pattern like '/{123}'.
---------------------------------------------------------------------------

Strangely enough Regex buddy gives no warning or error with the pattern.
Is the name all numeric invalid or just the beginning?
1e4 and 0xFF would be perfectly valid but returns true with is_nummeric()
---------------------------------------------------------------------------
by Tobion at 2012-09-06T08:59:07Z
Any numeric is not valid. I guess this limitation is unique to PHP's binding to PCRE.
I think it's because the returned matches array of of preg_match contains both the subpattern as integer index and as named variable. So having a numeric named variable would conflict as `array['1'] === array[1]`.
- The route compiler does not add extra space or line-feed,
- The generated regex does not use the 'x' modified any more,
- The PHP and apache matchers do not need to strip any chars (vs space and line feed before),
- The space characters are escaped according to the apache format
