Handle the deprecation of IntlDateFormatter::setTimeZoneId() in PHP 5.5.

Optionally use the new IntlDateFormatter::setTimeZone() method if it exists.
Fix version_compare() calls for PHP 5.5.

Until PHP 5.5 hits beta, the version number for Git builds is still 5.5.0-dev,
which is less than 5.5.0alpha1 according to version_compare(). This means that
the branches for 5.5 aren't being executed on 5.5 snapshots at present.

I guess that this could be related to #6496, as error code `267` at Windows means:
[`ERROR_DIRECTORY - The directory name is invalid.`](http://msdn.microsoft.com/en-us/library/ms681382%28v=vs.85%29.aspx#error_directory)

If null already uses the current working directory, what's the point of calling getcwd() at all?

---------------------------------------------------------------------------

by stloyd at 2013-01-08T13:03:06Z

@Seldaek TBH. I don't have idea =) It seems that it's there _from the beginning_, but yeah, I was a bit confused by usage of it too...

---------------------------------------------------------------------------

What about removing the code altogether?

---------------------------------------------------------------------------

by stloyd at 2013-01-09T08:22:55Z

@fabpot I'm ok with that, just not sure it will not be an BC break...

---------------------------------------------------------------------------

by Seldaek at 2013-01-09T08:24:57Z

php.net says `or NULL if you want to use the default value (the working
dir of the current PHP process)` which sounds like getcwd() to me.

---------------------------------------------------------------------------

by Seldaek at 2013-01-09T08:26:32Z

For full BC though, `getWorkingDirectory` should `return $this->cwd ?:
getcwd();` Then at least if that call fails the whole process isn't
failing. I don't see why anyone would use that getter though.

@fabpot @Seldaek What do you think about this now?

:+1:
Removed underscores from test method names to be consistent with other components.

It is more common to use fully camel-cased names for test methods. Only some of the test methods are called with underscore notation. To avoid confusion it is better to be consistent.

This is just a cosmetic change. It is more common (in Symfony) to use fully camel-cased names for test methods. Only some of the test methods contain underscores. To avoid confusion it is better to be consistent.

Redis profiler rows are not sorted as expected.

We have in redis:

```
- 2011-01-01 ...
- 2011-01-02 ...
- 2011-01-03 ...
```

If we limit to 2, we'll have:

```
- 2011-01-02 ...
- 2011-01-01 ...
```

Fixed this bug by reversing array.

IntlDateFormatter::setTimeZoneId() is deprecated in PHP 5.5, which results in E_DEPRECATED errors when using the date form type. This PR works around that.

Furthermore, the version_compare() tests used in locale to detect PHP 5.5 are broken with snapshot and Git builds of PHP. I've also committed a fix for those tests in this PR.

shouldn't it even be done in 2.0 as it is a bugfix ?

---------------------------------------------------------------------------

by LawnGnome at 2013-01-11T00:49:11Z

Possibly — I don't know enough about Symfony's release management to know whether this is appropriate for 2.0, and I was mostly scratching my own itch, honestly.

---------------------------------------------------------------------------

by stof at 2013-01-11T01:51:35Z

well, it is a bugfix and 2.0 is also impacted, so it should be done in it.

---------------------------------------------------------------------------

by LawnGnome at 2013-01-11T02:52:21Z

The diff for 2.0 looks like it'll be just the StubIntlDateFormatter.php changes — the deprecated method isn't called in DateType on that branch, and there aren't any StubIntlDateFormatter tests on 2.0. How do you want that submitted — as a separate PR against 2.0?

@LawnGnome A separate pull request would be good. Thanks.
