curl/lib/curl_get_line.c
Po-Chuan Hsieh 060f870b85 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
