* (global) Update code to match stream.h changes.
stream_get_putp effectively replaced with stream_get_endp.
stream_forward renamed to stream_forward_getp.
stream_forward_endp introduced to replace some previous
setting/manual twiddling of putp by daemons.
* lib/stream.h: Remove putp. Update reference to putp with endp.
Add stream_forward_endp, which daemons were doing manually.
Rename stream_forward to stream_forward_getp.
lib/stream.c: Remove/update references to putp.
introduce stream_forward_endp.
