[PATCH synaptics 3/4] syndaemon: document exit codes and change them to fall into categories.

[Peter Hutterer]

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.
