[JDEV] ECONNRESET check

Hey there Jabber-folks ...

I have had a problem with my transport server crashing when a client is killed without cleanly disconnecting from the socket first ... i.e. I control-c the rug out from underneath the carpet of my client app, so it doesn't get to send its logout message & do a socket close.  The read() call in io.c fails and h_err() kills my transport.

A small little fix takes care of this for me ... so I thought I'd mail it in & see if it helped out anyone else as well.

io.c:
diff io.c io.c.new
1a2
> #include <errno.h>
83c84,85
<                                               h_err(nbytes,"read");
---
>                                               if(errno != ECONNRESET)
>                                                       h_err(nbytes,"read");


This way if the connection was killed, then read() failing & returning -1 lets us "drop the connection" (and the user session) cleanly on our side.
