File Level PHPdoc for compat.php

[darkdragon]

The PHP compat functions aren't technically part of the WordPress package and only provides working implementations for PHP installations that are lacking upgraded versions.

The patch adds file level documentation that points out that the file is for providing support for used PHP functions going back down to PHP 4.2. The patch also packages the functions in another namespace and makes the functions private.

None of the functions are documented since documentation can be found at php.net.
