The pre-push testing I did turned out to be testing the old version with
the old testsuite (for reasons I don't understnad). There's issues with
the new version, the new test in the suite or (likely) both. Revert
until they can be chased down.

This should also fix the github CI that's gone red since this commit.

This reverts commit 3fd60a6b73ac01a72df89751f173970fae4cae73, reversing

Fix readrec's definition of a record. This fixes an issue
with NetBSD's RS regular expression support that can cause
an infinite read loop. Thanks to Miguel Pineiro Jr.

Fix regular expression RS ^-anchoring. RS ^-anchoring needs to
know if it is reading the first record of a file. This change
restores a missing line that was overlooked when porting NetBSD's
RS regex functionality. Thanks to Miguel Pineiro Jr.

Fix size computation in replace_repeat() for special case
REPEAT_WITH_Q. Thanks to Todd C. Miller.

Also, included the tests from upstream, though they aren't yet connected
to the tree.

We normally don't add $FreeBSD$ to contrib software. However, these
changes date back to the CVS era of source code management and have been
overlooked. Now that all these files are back to the same as the
upstream bsd-features branch, remove the FreeBSD specific changes, which
are now just $FreeBSD$ and the (FreeBSD) in the version string.

awk: revert to upstream behavior for ranges for gawk compatibility

In 2005, FreeBSD changed one-true-awk to honor the locale's collating
order. This was billed as a temporary patch. It was also compatible with
the then-current behavior of gawk. That temporary patch has lasted 16
years now.

However, IEEE Std 1003.1-2008 changed the behaivor of ranges in regular
expressions outside of the "C" and "POSIX" locales to be undefined.

Starting in 2011, gawk 4.0 stopped using the locale for the range
regular expressions and used the traditional behavior only. The
maintainer had grown weary of answering why '[A-Z]' would sometimes
match lower-case expressions. The details about are explained here:
https://www.gnu.org/software/gawk/manual/html_node/Ranges-and-Locales.html

To restore compatibility with other implementaitons of awk, revert this
patch. FreeBSD is the odd-system out. It also has the nice side effect
of eliminating the last of our differences with upstream one-true-awk.

awk: Reduce diffs with upstream to almost nothing.

In the merge of 20210215, I left two merge conflicts #if 0'd by mistake
to check later rather than resolve them as part of the merge. This code
turns out to be from the original one-true-awk import and not FreeBSD
specific, so remove them.

Remove a extra definition of HAT.

Remove a stylistic change that also appears to be a mismerge along the
way.

Remove FREEBSD-upgrade. Nobody has updated it since the original 2007
cvs import. It talks about old CVS branches that never made it into svn,
let alone git. New imports will follow the standard practices now, so
there's nothing left to document.

Move README to README.md and copy the README.md from upstream over.

This leaves just the $FreeBSD$ lines (which remain for the stable/12
merge) and the strcoll part of ru@'s r201989/d98dd8e5f94c as the only
diffs with upstream. FreeBSD also still has its own man page, which I
don't plan on changing. Once this commit is merged to stable/12, I plan
no further merges to stable/12. Sometime after that I'll remove the
$FreeBSD$ lines to reduce the diffs even more (though i want to make
sure plans won't change first). I also plan to talk to upstream about
this change...

Note: this backs out a number of changes we've made to awk because
they aren't upstream, but are on the vendor branch. Those will be
reapplied. svn makes it needlessly difficult to know which ones, but
at least r315426, r301289, and maybe r301691, though there may be
others too. None of these are critical, so bisecting through this
point is safe for all but awk regression tests :).
