sh: Restore $((x)) error checking after fix for $((-9223372036854775808))

SVN r342880 was designed to fix $((-9223372036854775808)) and things like
$((0x8000000000000000)) but also broke error detection for values of
variables without dollar sign ($((x))).

For compatibility, overflow in plain literals continues to be ignored and
the value is clamped to the boundary (except 9223372036854775808 which is
changed to -9223372036854775808).

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

sh: Remove #define MKINIT.

MKINIT only served for the removed mkinit. Many variables can be static now.

sh: Detect dividing the smallest integer by -1.

This overflows and on some architectures such as amd64 it generates SIGFPE.
Generate an error on all architectures.

In the spirit of r90111, depend on c89 and remove the "STATIC" macro
and its usage.

Consistently use "STATIC" for all functions in order to be able to set
breakpoints with in a debugger. And use naked "static" for variables.

Noticed by: bde

If DEBUG is 3 or greater, disable STATICization of functions.
Also correct the documented location of the trace file.

- Fix bugs where the value of arithmetic expansion$((...)) was trucated
to type int.
- Change the type used for arithmetic expansion to intmax_t (ie. 64 bit on all
currently supported FreeBSD architectures). SUSv3 requires at least type
long but allows for larger types. Other shells (eg. bash, zsh, NetBSD's sh)
do that too.
