[PATCH 05/17] Introduce reds_stream_new() helper

[Christophe Fergeau <cfergeau@xxxxxxxxxx>]

Initializing a new stream means initializing quite a few fields.
This commit factors this initialization in a dedicated reds_stream_new
helper. This also helps moving more code from reds.c to reds_stream.c
