- General changes:

- Remove -? from getopt(3) options, but still keep (or add) -h where applicable
- Replace hardcoded program strings by getprogname(3)

- Specific changes:
- atc(6): this used -? and -u for usage(), remove both from game and manpage
- bcd(6): use __progname instead of getprogname(3), no need to include stdlib.h
- hunt(6): replace fputs(3) by fprintf(3)

OK tb@ after his suggestions
