[PATCH 2/5] cli/reply: direct all output for text format to gmime stream

[David Bremner]

Interleaving printfs with writes to the gmime stream worked when the
gmime stream was backed by the FILE *stdout, but that is no longer the
case.  Create one stream and pass it into the two functions where
needed, as well well as replacing printfs with g_mime_stream_printf.
