Fix a (false positive?) Argument cannot be negative coverity defect.

Rather than guarding close(fd) with an fd >= 0 test and setting fd
to -1 when it is closed to avoid a potential double-close, just
move the close() call after the conditional "goto make_token". This
moves the close() call totally outside the loop to avoid the
possibility of calling it twice. This should also prevent a Coverity
warning about checking fd for validity after it was previously passed
to read().

random(6): Fix double-close

In the case where a file lacks a trailing newline, there is some "evil" code to
reverse goto the tokenizing code ("make_token") for the final token in the
file. In this case, 'fd' is closed more than once. Use a negative sentinel
value to guard close(2), preventing the double close.

Ideally, this code would be restructured to avoid this ugly construction.

Final step of eliminating the "games" distribution: Merge src/games
(or what's left of it, at least) into src/usr.bin.

This change will not be MFCed.

Add META_MODE support.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to

Still need to add real targets under targets/ to build packages.

Suggections from bde@
1) Split too long source lines
2) Portable code should not assume that null pointer == all-bits-0,
so back out prev. calloc() change.

Submitted by: bde

All cosmetic.
1) Rename RANDOM_MAX to RANDOM_MAX_PLUS1 to not confuse with random()'s max
2) Use calloc() instead of zeroing fields explicitly
3) "too many lines" -> "too many delimiters" for err()

1) Fix longstanding math bug with denominator > 1 (wrong probability).
Test case:
random -f some_small_file 10000
(in most cases must be no output)
2) Prevent number of lines > RANDOM_MAX (overflow or nothing may be
choosed) with EFBIG err()
3) After line is found, terminate list loop for -U case too,
since nothing to do in the rest of the loop left.

I was confused a bit by the wrong construction with RAND_MAX
used in randomize_fd.c.
Although the max value is the same currently, RAND_MAX is for rand(),
not for random().
So move RANDOM_MAX const to the common file now, make it UL and
use in randomize_fd.c too.
(in any case its old value was 1 less then must be, as noted in
the prev. commit)

1) Replace hardcoded RANDOM_MAX macro with wrong (1 less than must be)
value with ((double)RAND_MAX + 1)
2) For exit code increase valid denominator upper range from 255 to 256
since returned value is [0 .. denom - 1]

1) Fix hang at the end of line buffer (PR 95715)
2) Localize

Correct an error in the previous revision. RAND_MAX is the maximum value
for rand(3), not random(3). random(3) is defined to return values between
0 and 2^31-1, so add a local RANDOM_MAX constant to this file that is
defined as 2^31-1 and use that in place of RAND_MAX.

Sync program's usage() with manpage's SYNOPSIS.

Sort sections.

Properly initialise 'filename' so that random -l doesn't try to open NULL.

Const-qualify 'filename' to avoid a strdup() call due to -Wwrite-strings
silliness.

Make the __FBSDID usage consistent
and protect copyright[] from Gcc 3.3's whining.

Fixed SYNOPSIS.
Expanded stdin/stdout definitions.
Ordered the SEE ALSO references.
Moved some chat from the BUGS section to freebsd-chat@.
Removed ``cvs log'' material from the HISTORY section.

flexlint rears its head as well as some style(9) fixes[1]. Fixed a
few bugs for a few corner cases and correctly handle the case where
read(2) is read()'ing from a non-file descriptor and could get fewer
bytes back than the buffer, but it isn't EOF[2]. random(6) extensively
tested and believed to be bug free (save performance for large files).

The $Id$ line is normally at the bottom of the main comment block in the

like so;

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

EOF? The getopt(3) manpage clearly states that the return value is *-1*,
not EOF! Besides, getopt(3) isn't reading from a file. :)
