ext/curl safe_upload is changed

Hey Stas: I noticed that this change : https://github.com/php/php-src/commit/24447dca it has broken some tests in ext/curl... did you run make test before? Anyway, the current behavior is silent return if the codes uses old upload style("@filename"); I think it's better to throw a warning or something error about that.... thoughts? thanks -- Laruence Xinchen Hui http://www.laruence.com/
