Rebase cmn_err on vcmn_err and don't warn about missing \n 

The cmn_err/vcmn_err functions are layered on top of the debug
system which usually expects a newline at the end.  However, there
really doesn't need to be a newline there and there in fact should
not be for the CE_CONT case so let's just drop the warning.

Also we make a half-hearted attempt to handle a leading ! which
means only send it to the syslog not the console.  In this case
we just send to the the debug logs and not the console.
