Unique blacklist-classnames for php-code-coverage & phpunit

[hpbuniat]

This is a follow-up to #226

The same "error" was caused by PHPUnit_Util_Blacklist, so i moved the classes to a static property, which can be used by phpunit (pull-request will be referenced).

SebastianBergmann\Comparator\Comparator is missing, as this is currently only part of the master-branch.

I'd like to use this opportunity and move the list to PHPUnit and have it push it to PHP_CodeCoverage.

I wasn't completely sure, where it really belongs :)

[sebastianbergmann]

That is because the answer to that question is rather tricky. :-)

Before the list was duplicated in both PHPUnit and PHP_CodeCoverage. This caused the obvious problems usually associated with duplication.

Now that I have merged sebastianbergmann/phpunit#1195 and #227 that duplication is gone (good!) but PHPUnit uses a data structure that belongs to PHP_CodeCoverage (bad!).

For PHPUnit 4.1 (and PHP_CodeCoverage 2.1, respectively) I would like PHPUnit to own the list and push it into PHP_CodeCoverage. This means, of course, that a client of PHP_CodeCoverage (such as PHPUnit) is responsible for filling the default blacklist. This is not perfect either, but IMHO better than what we have now.
