maint: use EXIT_SUCCESS and EXIT_FAILURE, not 0 and 1 to exit

Convert all uses automatically, via these two commands:
git grep -l '\<exit *(1)' \
  | grep -vEf .x-sc_prohibit_magic_number_exit \
  | xargs --no-run-if-empty \
    perl -pi -e 's/\b(exit ?)\(1\)/$1(EXIT_FAILURE)/'
git grep -l '\<exit *(0)' \
  | grep -vEf .x-sc_prohibit_magic_number_exit \
  | xargs --no-run-if-empty \
  perl -pi -e 's/\b(exit ?)\(0\)/$1(EXIT_SUCCESS)/'
* .x-sc_prohibit_magic_number_exit: New file.

Edit (RWMJ): Don't change Java code.
