Remove $FreeBSD$: one-line .c pattern

Remove /^[\s*]*__FBSDID\("\$FreeBSD\$"\);?\s*\n/

Clean up the vcs ID strings in libc's gen/ directory.

- Move CSRG IDs into __SCCSID().
- When a file has been copied, consistently use 'From: <tag>' for strings
referencing the version of the source file copied from in the license
block comment.
- Some of the 'From:' tags were using $FreeBSD$ that was being expanded on
each checkout. Fix those to hardcode the FreeBSD tag from the file that
was copied at the time of the copy.
- When multiple strings are present list them in "chronological" order,
so CSRG (__SCCSID) before FreeBSD (__FBSDID). If a file came from
OtherBSD and contains a CSRG ID from the OtherBSD file, use the order
CSRG -> OtherBSD -> FreeBSD.

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.

Per Regents of the University of Calfornia letter, remove advertising
clause.

# If I've done so improperly on a file, please let me know.

Back out the `hiding' of strlcpy and strlcat. Several people
vocally objected to this safety belt.

`Hide' strlcpy and strlcat (using the namespace.h / __weak_reference
technique) so that we don't wind up calling into an application's
version if the application defines them.

Inspired by: qpopper's

Return the correct environment name for 64-bit platforms in the
_CS_POSIX_V6_WIDTH_RESTRICTED_ENVS case.

Assume that my bug report against 1003.1-2001 will be resolved my way,
and make 64-bit architectures use the LP64_OFF64 environment instead
of the LPBIG_OFFBIG one.

Support POSIX/SUS ``programming environment'' mistake in confstr().

All of the things that confstr() returns are compile-time constants.

All of the things that confstr() returns are compile-time constants.
It's silly to call sysctl() to get the value of _PATH_STDPATH from
<paths.h> when we can just use it directly. This greatly simplifies
the implementation. (This is also part of my grand scheme to get
rid of sysctl's `user' category, which should never have been created.)

Use strlcpy() instead of strncpy() as it has the exact semantics we want.

Fix the style of the SCM ID's.
I believe have made all of libc .c's as consistent as possible.

Minor cleanup, mostly unused vars and missing #includes.
