Remove copyright strings ifdef'd out

We've ifdef'd out the copyright strings for some time now. Go ahead and
remove the ifdefs. Plus whatever other detritis was left over from other
recent removals. These copyright strings are present in the comments and
are largely from CSRG's attempt at adding their copyright to every
binary file (which modern interpretations of the license doesn't
require).

This allows an endless stream of random data within the given bounds.

capsicum: use a new capsicum helpers in tools

Use caph_{rights,ioctls,fcntls}_limit to simplify the code.

Convert `cap_enter() < 0 && errno != ENOSYS` to `caph_enter() < 0`.

No functional change intended.

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.

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.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

- Import the HEAD csup code which is the basis for the cvsmode work.

Use explicit braces to avoid ambiguous else.

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.

MFC after: 2 weeks

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.

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).

Avoid passing negative values to <ctype.h> functions on machines with

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.

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.
