MEDIUM: mux-h1: don't use CS_FL_REOS anymore

This flag was already removed from other muxes and from the upper layers,
because it was misused. It indicates to the mux that the end of a stream
was already seen and is pending after existing data, but this should not
be on the conn_stream but internal to the mux.

This patch creates a new H1S flag H1S_F_REOS to replace it and uses it to
replace the last uses of CS_FL_REOS.
