* include/wget/wget.h: New function declaration wget_http_connection_receive_only(). * libwget/http.c: New function definition wget_http_connection_receive_only(). * libwget/http.h (struct wget_http_connection_st): Add member goaway. * libwget/http2.c (struct http2_stream_context): Add member conn, (on_frame_recv_callback): Handle NGHTTP2_GOAWAY, (wget_http2_send_request): Initialize conn member. * src/host.c (_release_job): Don't release parts if in 'done' state. * src/wget.c (process_response_header): Remove handling of LINK headers, (process_response): Add handling of LINK headers, (downloader_thread): Handle pending responses correctly. This patch fixes two related issues: 1. With HTTP/2, servers sometimes limit the number of requests per connection. Beforethis patch, the connection was closed too early after GOAWAY and pending responses weren't received. 2. In _release_job(), already downloaded parts of a file were erroneous released. This caused successful metalink and chunked downloads to fail in combination with a GOAWAY or a remotely closed connection.
