PREG_BACKTRACK_LIMIT_ERROR encountered during WP import

[ryan]

The WordPress importer uses preg_match_all to slurp items from the import file. Large items can cause a PREG_BACKTRACK_LIMIT_ERROR. This can be avoided by bumping pcre.backtrack_limit, but that isn't very friendly. Instead, the importer shouldn't use preg_match_all. There are other ways of retrieving the items.

(In [5422]) Don't preg_match_all when processing items. fixes #4239 for 2.2

Testing went well, so I committed for 2.2 since this bug sucks for those affected.
