Rework random(6)

Fix putchar(3) handling and a number of other issues in the random(6)
code. In -e mode, avoid bias due to truncation of the return code to
8 bits. In default mode, actually treat the denominator as a floating
point number and print the line with a probability of 1 / denominator.
This allows e.g. printing 2/3 of stdin with 'random 1.5'.

Includes code for uniform random floats by Taylor R. Campbell from
https://mumble.net/~campbell/2014/04/28/uniform-random-float
and clz64() by me.

From lucic71 () bronze ! ctrl-c ! club, thanks.

- 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)

Some basic code maintenance in games/

- in main() replace exit with return
- drop some /* NOTREACHED */ lint comments along the way.
- make more use of standard CFLAGS, esp. -Wimplicit-function-declaration
- add and sort some headers when needed
- add straightforward pledges to some programs used at compile time

More headers removal and sorted the remaining alphabetically.

Most noticeable that were removed are sys/types.h which will be included from
stdlib.h and in turn also brings along sys/cdefs.h. The other one is limits.h
that was used with the old idiom (denom * random() / LONG_MAX), although it was
only removed were applicable (some files still need that header).

About 13 years ago when the idiom srandom(time()), and sometimes
srandom(time()+getpid()), was changed by srandomdev(), but #include <time.h>
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.

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable).  these days, people use source.  these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)
ok with the idea millert, ok dms

Part one of userland __P removal.  Done with a simple regexp with some minor hand editing to make comments line up correctly.  Another pass is forthcoming that handles the cases that could not be done automatically.
