    altsvc: Fix building with cookies disables
    
    ALTSVC requires Curl_get_line which is defined in lib/cookie.c inside a #if
    check of HTTP and COOKIES. That makes Curl_get_line undefined if COOKIES is
    disabled. Fix by splitting out the function into a separate file which can
    be included where needed.
    
    Closes #3717
