Log Message:
Resolve undetected or infinitely-retried socket-send failures

My hub (1:218/700) is currently having what appears to be a TCP/IP
connectivity issue that was resulting in infinite "Send failure"
log messages and "We got an M_EOB, but there are still N files pending M_GOT" log messages.

I first added better socket-send failure detection (checking return value of sendCmd() and sendData() where needed) and then noticed that failure to send
a file was not detected (the sending.file.position is advanced even if sendData() fails), so now handling that condition too.

Also added more diagnostics around socket-send failures (is socket writable?) in this particular case, the socket is not writable and socket-send is returning 0.

Log Message:
Use socket.poll() to check socket for writability before send()

This is the real fix for infinite-wait on send() problem that was attempted
in commit f0127e9d457, but caused other issues. Thanks Deuce.

Log Message:
Don't log BinkP errors in the error.log

The sysop has no control over what misconfigured remote sysop connects to his BinkP service and sends whatever, so don't log received errors as errors, filling up the sysop's error log and potentially email inbox.
