Modified Files:
        src/bin/rcp: rcp.c

Log Message:
Fix bug revealed by SIGINFO support; Do not treat short read(2)/write(2)
as error (*). This occurs typically when signal is received.

(*) For older version, we already deal with short read(2) from remote
host in sink(). But for other cases, i.e., write(2) to local file in
sink(), read(2)/write(2) in source(), error was raised.

This version of rcp(1) can successfully send/receive files with older
version, even if short read(2)/write(2) occurs by SIGINFO.

Also, when real error occurs, give up immediately instead of continue to
send/receive wrong data.

Clean up the mess a little bit as well...
