[Session] fixed wrong started state

Currently the session stays in the started mode after the call of  ```save()``` which will close the session. We found the issue in our custom SAPI which keeps the symfony stack initialized over multiple requests.

Replaced the @inheritdoc with an actual list of params since the original method has a different signature.

Also, fixed indentation in other docblocks.

`BinaryFileResponse::create()` has a different signature than `Response::create()` and cannot inherit its doc. I also fixed indentation in other blocks in this file.

[Stopwatch] Fix tests on Travis (also vagrant)

Travis often fails to run tests related to the Stopwatch Component, check it yourself:

- https://travis-ci.org/symfony/symfony/jobs/12340378
- https://travis-ci.org/symfony/symfony/jobs/12365787
- https://travis-ci.org/symfony/symfony/jobs/12365790

- https://travis-ci.org/symfony/symfony/jobs/12371316
- https://travis-ci.org/symfony/symfony/jobs/12375730

This is because Travis is just slow as hell. So I just multiply the used usleep by 10.
