GH-4491 - Move patch from master to 2.0

A patch in PR-4469 fixed an issue with setLenient() and not having intl. This was only merged into master, although the original issue was created in the 2.0 branch. This PR cherry-picked the patches against 2.0 again.

[Yaml] Fixed double quotes escaping in Dumper

Issue #4308 is caused by Dumper::escapeWithDoubleQuotes() which uses [str_replace()](http://php.net/str_replace).

From the php docs:

> Because str_replace() replaces left to right, it might replace a previously inserted value when doing multiple replacements.

We should be very careful in deciding about the order of elements in $escapees array. I'd really appreciate if someone reviewed my fix. Tests say I didn't break anything but I'm not sure what percentage of Yaml specification is covered by tests.

Bug fix: yes
Feature addition: no
Backwards compatibility break: not that I know
Symfony2 tests pass: [![Build Status](https://secure.travis-ci.org/jakzal/symfony.png?branch=yamlDoubleQuotesDumperFix)](http://travis-ci.org/jakzal/symfony)
Fixes the following tickets: #4308

Something is really wrong with this method. You can see clearly that multiple characters would fail proper escaping.

Here's an example:
```
$value = '\\\\"some value\n \"some quoted string\" and \'some single quotes one\'"';
var_dump(Escaper::escapeWithDoubleQuotes($value));
string(72) ""\\\"some value\n \\some quoted string\\ and 'some single quotes one'\"""
```

To begin with the backslash - in the initial value you have 2 (escaped ones), that after escaping should result in 4, not in 1 (escaped). I guess this behavior has to be verified with the importer, but imho it does not seem right.

Does anyone know why this escaping wasn't done using a regular expression in first place?

Searching for https://duckduckgo.com/?q=what+is+\xc2\x85 the table on http://stackoverflow.com/questions/6609895/efficiently-replace-bad-characters is interesting enough to decide we need way more documentation on this file.

\xc2\x85 seems to be triple dot (ellipses)
\xe2\x80\xa9 seems to be paragraph separator see http://drupal.org/node/914360#comment-3468550
