Re-promote some GNU warnings to errors (#1508)
* Promote some GCC warnings back to errors and deal with build breakage.
I tested configuring and building with GCC 8.3.0 with

`.../configure --prefix=$HOME/wrk/install/manydsets --enable-build-mode=production --enable-symbols=-gdwarf-4 --enable-warnings-as-errors --enable-java --enable-hl --enable-fortran --enable-cxx --enable-mirror-vfd --enable-ros3-vfd --enable-direct-vfd`

and with the same options but `--enable-build-mode=debug`.

* Promote -Wrestrict to -Werror=restrict to help catch overlapping
arguments to strcpy, memcpy, et cetera, at compile time.

* NFCI: sort lines.

* Committing clang-format changes

* NFCI: remove whitespace at EOL.

* Re-use temporary variable `shared`.

* Remove merge oopsie.

* Mention that no op codes are understood per review comment.

* Change this back to the develop branch's way, since this change isn't
integral to the PR.

* Committing clang-format changes

* NFCI: reduce differences with `develop` branch in the hope that that
also kicks off CI.
