Add verbose option to codasrv

[krichter722]

According to man codasrv there's no option to get verbose information logged to console (useful in conjunction when running the program in foreground mode/without forking/daemonizing).

Well it isn't called '-verbose', but there is '-debug ' which turns up verbosity of what gets written to /vice/srv/SrvLog and /vice/srv/SrvErr. Because there is a lot of output at a high debug level, writing to the console isn't terribly useful because you can only scroll back as far as your terminal (or screen) buffer allows.

Also because we are a cooperatively threaded program, when the server blocks on writing to the console, it blocks everything. So the combination of a lot of output and an often slow ssh terminal connection affects significantly how the server behaves.

Actually it is '-d ', and the server will only daemonize itself when the debug level is set to 0. So you would get the desired keep server in the foreground effect by just running,

codasrv -d 1

So now you only have to teach systemd to read the right logfile.

The manpage should be updated because it's neither clear how to keep codasrv from forking nor does it explain the required argument - I assume a digit between 0 and 5, but it could be another range or a string as well., so it should be explained.
