Allow read-only or non-existing sink input volume.

Browse source 
There are two known cases where read-only or non-existing sink input volume is
relevant: passthrough streams and the planned volume sharing logic.
Passthrough streams don't have volume at all, and the volume sharing logic
requires read-only sink input volume. This commit is primarily working towards
the volume sharing feature, but support for non-existing sink input volume is
also added, because it is so closely related to read-only volume.

Some unrelated refactoring in iface-stream.c creeped into this commit too (new
function: stream_to_string()).
