I'm not a big fan of this fix, but - at least - it works.

With this code, finally, Process does not behave the same at all on Windows and Linux.
This patch does not smells very good but it solves the random failing test issue (that produced at runtime too).

Actually, calling `proc_get_status` within the waiting loop introduced the bug.
So this PR reverts to the previous behavior (consider a process running as long as pipes give data). On Windows, this is not the same behavior as we're not using streams but file handles. Whereas the feof of a stream is detected when the other side closes, the feof of a file handle can be reached at any time. So, on Windows, `proc_get_status` is called (checking the feof of the file handle might be positive until the executable outputs something), and we consider a process running as long as the information returned says it's running.

We could think of decouple windows and linux logic in two separated objects, using the interfaces I introduced in #8753. This could bring much more readability and make the code more easy to understand.

Po files should not be dumped without a header. It causes a lot of problems, including charset issues.

See #6765 / 1 for more info

[FrameworkBundle] assets:install command should mirror .dotfiles (.htaccess)

The `assets:install` command currently ignores all *.dotfiles* when mirroring the `Resources\public` folders of bundles. This can lead to issues when *.htaccess* files are required for some public assets (ie.: CORS headers for font files to be served via Cloudfront).

Since the assets being installed are clearly in a folder called `public`, we can safely assume that those files are in fact supposed to be accessible and copy them over with the normal files.

[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.
