[PATCH 41/41] exit.cocci: use the stdlib EXIT_SUCCESS or EXIT_FAILURE exit status

The C standard specifies two constants, EXIT_SUCCESS and EXIT_FAILURE, that may be passed to exit() to indicate successful or unsuccessful termination, respectively. The value of status in exit(status) may be EXIT_SUCCESS, EXIT_FAILURE, or any other value, though only the least significant 8 bits (that is, status & 0377) shall be available to a waiting parent proces. So exit(-1) return 255.

Add a coccinelle semantic patch for using the C standard EXIT_SUCCESS and EXIT_FAILURE to indicate the program exit status instead of "0" or "1", respectively. In <stdlib.h> EXIT_FAILURE has the value "1": use EXIT_FAILURE even if the program uses exit(-1), ie 255, for consistency.
