- optarg and optind are declared by unistd.h, so remove them...

- use strtonum rather than atoi - zap case '?' in getopt(3) switch - use _exit(2) in signal handler - use __progname in usage() instead of hardcoded name OK tb@ mestre@

Remove unused header

About 13 years ago when the idiom srandom(time()), and sometimes

2016-01-03T14:38:16Z

srandom(time()+getpid()), was changed by srandomdev(), but #include lived up until this day so remove it. Additionally, earlier than that, 18 years ago, random(6) was one of the first consumers of arc4random(3) family, and was pulling it from dev/rndvar.h but these days we pull it from stdlib.h, which is already done, so while here remove dev/rndvar.h also. "seems comprehensive to me" deraadt@ and OK tb@

Declare usage() functions as __dead void, if they don't return, on games section.

Found another one in arithmetic(6) which also didn't return, and removed a function from number(6) which is not used anymore. OK tb@

Cast ctype functions' arguments to unsigned char.

Pledge that arithmetic only takes "stdio".
