Added initial support for --next/-: which will be used to replace the
rather confusing : command line operation what was used for the URL

Follow up to commit 1a9b58fcb2 to replace the : command line option
with --next and -:.

In addition to adding support for URL specific options via the command
line with --next it is now possible to specify "next" in .curlrc.

http2: build with current nghttp2 version

nghttp2 has yet again extended its callback struct and this is an
attempt to make curl compile with nghttp2 from current git
Fix bug that HTTP/2 hangs if whole response body is read with headers

For HTTP/2, we may read up everything including responde body with
header fields in Curl_http_readwrite_headers. If no content-length is
provided, curl waits for the connection close, which we emulate it
using conn->proto.httpc.closed = TRUE. The thing is if we read
everything, then http2_recv won't be called and we cannot signal the
HTTP/2 stream has closed. As a workaround, we return nonzero from
data_pending to call http2_recv.
transfer.c: Fixed non-HTTP2 builds from commit cde0cf7c5e
