8a16b7a18f 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.

f03b27517b Store a pointer to "null" in struct ndblock's defn member instead of a
duplicate allocated on the heap; the address defn points to is significant,
and is checked against the address of "null" in certain conditionals.

ccc5b4e6f4 Crank WARNS.
Cast sizeof() to (int), as it's being compared against an int, not a size_t.
If i is changed to a size_t, it means the logic must be slightly changed later
in the flow, where --i is checked to be >= 0.  I am not sure I want to make a
logic change to account for clearing up a warning, when an aesthetic one will
keep from modifying the logic.

Other harmless casts, that I think I've made in the right directions.

Make gpbc() an inline function, rather than an obfuscated macro, make its
scratch space local, rather than global.  The previous macro used a dirty
hack (logical AND in place of a conditional) which would lead GCC to throw
a fit (rightly so) as the logical check, as well as the incrementation of
a variable, were not used for anything.

const'ify a few places where gcc3 yells. xstrdup() some global consts in
places where we xstrdup() when not using consts, but tried to assign them
to non-consts before.

Don't use execv(2) if we don't have the kind of arguments it wants.

4ba4d3873a String operations could silently truncate long strings, leaving the output
corrupted.  Mark's patch fixes this be removing the MAXTOK limitation on
substring operations and allowing the putback buffer size to be the limiting
factor.  If the putback buffer size if reached, m4 gives an error instead of
silently truncating the string.

This patch has been submitted by Andreas Burmester (i think) on the
German Usenet long ago.  Andreas told me that our m4 has quite more
subtle bugs, so we might consider using NGU m4 instead.
