usr.bin: Remove ancient SCCS tags.

Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

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.

Add support for multibyte characters. The challenge here was to use
data structures that scale better with large character sets, instead of
arrays indexed by character value:
- Sets of characters to delete/squeeze are stored in a new "cset" structure,
which is implemented as a splay tree of extents. This structure has the
ability to store character classes (ala wctype(3)), but this is not
currently fully utilized.
- Mappings between characters are stored in a new "cmap" structure, which
is also a splay tree.
- The parser no longer builds arrays containing all the characters in a
particular class; instead, next() determines them on-the-fly using
nextwctype(3).

No functional changes, just code reorganization from prev. commit, it
makes one malloc unneeded, removes two bzero's and makes code more readable.

POSIX requires 'c-c' must conform collate and be in collation order

This patch address two problems.

1st one is relatively minor: according our own manpage, upper and lower
classes must be sorted, but currently not.

2nd one is serious:

This patch address two problems.

1st one is relatively minor: according our own manpage, upper and lower
classes must be sorted, but currently not.

2nd one is serious:
tr '[:lower:]' '[:upper:]'
(and vice versa) currently works only if upper and lower classes
have exact the same number of elements. When it is not true, like for
many ISO8859-x locales which have bigger amount of lowercase letters,
tr may do nasty things.

See this page

for detailed description of desired tr behaviour in such cases.

Bump the size of the equivalence set to NCHARS; this file was left out
of a previous commit implementing equivalence classes.
