Revert some refcount changes on I/O structs.
These are refcounts on structs, not Tcl_Obj's. Their scheme doesn't suffer the same difficulties and histories as Tcl_Obj's, and they need not copy every detail, appropriate or not, from Tcl_Obj refcount management. The "significant value" -- as dkf puts it -- for the struct refcounting scheme is 0 not 1.
