95b7f0209b Fix 'jot -r 0 start end' to work.
This allows an endless stream of random data within the given bounds.
It already worked if a seed was provided as the 4th argument but not
if one was left out.

872b698bd4 General further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

7e6cabd06e Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

af51ff2234 Prevent buffer overflow when forcibly terminating an escape character.
Obtained from:	OpenBSD
Note: In the case of a full buffer the OpenBSD implementation will
leave in the format string an invalid escape sequence.  This appears
to be harmless with our C library, but according to C99 this can
cause undefined behavior.

552b6c0ead Correct handling of format strings with escaped % specifications.
Note: It would be nice to be able to implement getformat() using
fmtcheck(3), but fmtcheck does not distinguish between signed and
unsigned types, a facility jot needs to perform range checks on its
output.

c15edb9d96 Do What I Mean when the user asks for random integers or characters.
Up to now jot would fail to generate the last character in the range
or skew the integer distribution in a way that would generate the numbers
in the range's limits with half the probability of the rest.

This modification fixes the program, rather than documenting the
strange behavior, as suggested in docs/54879.

Also, correctly specify the range of random(3).

cff48d6f3f Fix jot so that 'jot -r -w %d 1 1 4' never prints 4. Previously, it
would print it with probability 1/2**32.  It seems that the correct
behavior is to print 4 with probability 1/4, but I'd like to avoid
breaking POLA until all the range inconsistencies in jot can be fixed
in one pass.  See PR for details.

e68b7c9ebf Actually, arc4random() returns a uint32_t, not an int. Use the correct
constant, just in case uint32_t turns into a `short' ten years from now.
If this is MFC'd it will be necessary to hard-code the constant since
-stable doesn't have UINT32_MAX.

dda28cb6eb Miscellaneous cleanups; sync to OpenBSD as much as feasible.
Noteworthy changes include:
 * Use getopt(3).
 * Fix overflows in -b and -w options.
 * Use strlcpy(3) and snprintf(3) in favor of strcpy(3) and
   sprintf(3), respectively.  Also check return values of the former
   two.
 * Fix lots of other gratuitous differences with OpenBSD.
