Subject: [PATCH] Petidomo needs to know the path to the executable in order to
 write the ack-spool file, which starts Petidomo again to process the
 acknowledged command or posting. I used BINDIR for that, but realized that
 this sucks when somebody manually moves the binary. Hence, I am using the
 contents of argv[0] now, normalized to an absolute path. This value is stored
 in the global variable who_am_i, which the queue_*() routines now use.
