Add formatting/static analysis (#486)
* Reform source with clang-format.

Rules applied with:
    $ find . -iname *.h -o -iname *.cc | xargs clang-format \
        -style=file -i -fallback-style=google

* Add clang-format and analyze to build.

Based on the excellent work at: https://github.com/ttroy50/cmake-examples

* Clean up CMake stuff on macOS.

* Remove vim/emacs modelines.

* Update copyright dates.

* Build fixes.

* Build fixes.
