We're starting to propagate the stream connector's new name through the API. Most call places of these functions that retrieve the channel or its buffer are in applets. The local variable names are not changed in order to keep the changes small and reviewable. There were ~92 uses of cs_ic(), ~96 of cs_oc() (due to co_get*() being less factorizable than ci_put*), and ~5 accesses to the buffer itself.
