This is the result after running 'clang-format -i' on all C++ files and
headers, with the defined formatting rules in .clang-format.

Linux has a filename maximum of 255 chars, but we need to
be careful about the composition of the temporary filename
so that we don't exceed this limitation on the temporary,
even when the original is within the limit.
