get_headers patch

This is a update of the get_headers patch i sent in a long time ago and was ignored. Patch is written with the latest cvs snapshot of 5.1. Hope it makes it way to 5.1.1 Info: mixed get_headers ( string url [, bool format | string header [,resource context]]) 2nd arg can eather be bool or string bool: true returns an numeric indexed array with headers false returns key index array with header name as key string: returns only the header with the same name. passing long will cast E_STRICT but still work the old way 3nd arg is a context to pass header/data to the url.
