[FrameworkBundle] Added a check on file mime type for CodeHelper::fileExcerpt()

Fixed a bug on `CodeHelper::fileExcerpt()`.

I add a check on the file mime type because I use a phar of phpunit and when a exception throwed in a test, Symfony build a page with the stack trace of the exception.

The phpunit.phar path is in the stack trace and Symfony call `highlight_file()` function on this file path.
`highlight_file()` cannot parse the phar file and warnings are displayed.

This PR add a check on the file mime type.
**This PR can be applied on 2.0, 2.1 and master branches.**

Bug fix: yes
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: yes (The broken test seems to be unrelated to this change)

[FrameworkBundle] used the new method for trusted proxies

This makes the framework bundle using the new method from the request class.

As this is a sensitive issue, can you add some tests? Thanks.

Well I don't know why it fails on travis, I can't run the full test suite locally because of a segfault but ```phpunit src/Symfony/Bundle/``` marks all the tests as passing.

But it looks like the failing tests come from what you've changed.

Yes, I'm not saying it's not my fault but I can't reproduce this as locally it tells me they pass, I'll try to fix this this evening.

Apparently it fails only when running the whole testsuite, looking at other travis builds I can see this one on 2.0 : https://travis-ci.org/symfony/symfony/jobs/3495511 which fails in a similar way than here (https://travis-ci.org/symfony/symfony/jobs/3530928). Because of a place trying to access an undefined $_SERVER key : ```PHP Notice:  Undefined index: SCRIPT_NAME ...``` but I can't find where, and the stack trace references some phpunit classes.

I'd be happy if someone could give me some pointers in here as I don't have any clue about how to fix this..

As a consulsion I'd say I can't run the whole testsuite locally (it fails even when I revert my commit), so there is no reliable way for me to fix this, if anyone is up for continuing this feel free.

@bamarni Can you just update this PR with the code change and no tests at all? I will then finish the PR. Thanks.
