Implement alternative to on boost::split

boost::split has a documented false-positive in clang-tidy.  While
normally we'd handle this with NOLINTNEXTLINE, this doesn't appear to
work in all cases.  Unclear why, but seems to be due to some of our
lambda callback complexity.

Each of these uses is a case where we should be using a more specific
check, rather than split, but for the moment, this is the best we have.

Tested: clang-tidy passes.
