syndaemon: document exit codes and change them to fall into categories.
Changing pid file creation failure to same exit code that fork() failure uses. Changing XRECORD init failure to unique code. This way clients can trap exit code 4 and re-start syndaemon without the -R flag. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
