Make pw_scan(3) more compatible with getpwent(3) et. al. when processing
data from /etc/passwd rather than /etc/master.passwd.

The libc getpwent(3) and related functions automatically read master.passwd
when run by root, or passwd when run by a non-root user. When run by non-
root, getpwent() copes with the missing data by setting the corresponding
fields in the passwd struct to known values (zeroes for numbers, or a
pointer to an empty string for literals). When libutil's pw_scan(3) was
used to parse a line without the root-accessible data, it was leaving
garbage in the corresponding fields.

These changes rename the static pw_init() function used by getpwent() and
friends to __pw_initpwd(), and move it into pw_scan.c so that common init
code can be shared between libc and libutil. pw_scan(3) now calls
__pw_initpwd() before __pw_scan(), just like the getpwent() family does, so
that reading an arbitrary passwd file in either format and parsing it with
pw_scan(3) returns the same results as getpwent(3) would.

This also adds a new pw_initpwd(3) function to libutil, so that code which
creates passwd structs from scratch in some manner that doesn't involve
pw_scan() can initialize the struct to the values expected by lots of
existing code, which doesn't expect to encounter NULL pointers or garbage
values in some fields.

Revert r336619, it appears to cause problems with ssh, and probably other
things which use pw_scan().

Set the pw_class field to NULL when scanning the non-master passwd file.
This avoids a null pointer deref in pw_dup(), which assumes that all
pointers are either NULL or valid.

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.
