extract clone duplication logic in exceptionlistener

Drupal needs potentially to adapt the exception listener to add more information from the original request. (see http://drupal.org/node/2057607) so what about extracing some of the logic into a new method.

always manually inherit $_SERVER

The $_ENV superglobal is not populated if E is not present in the variables_order directive. Since populating this variable is not recommended (for performance reasons), we should not rely on it.

This change updates the builder so $env=null is never passed to proc_open(). Instead we always merge the $_SERVER superglobal into any environment variables that were manually set on the builder (unless inherit has been disabled).

The `$_ENV` superglobal is not populated if `E` is not present in the `variables_order` directive. Since populating this variable is not recommended (for performance reasons), we should not rely on it.

This change updates the builder so `$env=null` is never passed to `proc_open()`. Instead we always merge the `$_SERVER` superglobal into any environment variables that were manually set on the builder (unless inherit has been disabled).

This is a copy of PR https://github.com/symfony/symfony/pull/8067 by @kriswallsmith. I have created a new PR because there were some failing tests and kriswallsmith seems to have no time to rebase.
