because we no longer have to convert strings from unicode, we can avoid copying them out of the upcall buffer

when open parsing fails, we were still returning upcall.status==NO_ERROR, so the driver assumed the open succeeded. other operations then sent up an open_state==NULL, and crashed the daemon. when upcall_parse() returns an error, set upcall.status to notify the driver
upcall_parse() prints a 'parsing of upcall <name> failed with <error>.' message on failure, so i removed redundant messages from the individual upcall parsing functions

if readdir fails to look up a referred entry, set its type to NF4DIR so windows explorer shows it as a directory. when you double-click on the directory, it gives a message saying that it "refers to a location that is unavailable"
