extending ignore_errors inside http_fopen_wrappers.c

Hi, I've been extending the pecl/oauth code to work with php stream wrappers in cases whereby curl is not enabled, but I've hit a snag. The documentation states that enabling the "ignore_errors" flag will fetch the content even on failure status codes. At the same time, setting "max_redirects" to <= 1 indicates that no redirects will be followed. It does not state that setting "max_redirects" <= 1 would actually trigger an error, though in the code it returns (php_stream *)NULL making it impossible to even get the headers out of the wrapperdata hash unless STREAM_ONLY_GET_HEADERS is used. So, either setting "max_redirects" <= 1 should not throw NULL back into the caller code or "ignore_error" behaviour should be extended to prevent that from happening. My attached patch favours to fix the latter, since the "ignore_errors" is a relatively new flag. Hope it will be accepted for the 5.3 release. (not sure whether attachments will be allowed ... give me a ping if it doesn't make it through) Best,  Tjerk
