We currently use a mix of C standard includes (e.g. limits.h) and their C++ variants (e.g. climits). This migrates to a consistent style for all cases where the C++ variants are acceptable, but leaves the C equivalents in place where they are required, such as in the embedder API and other headers that may be used from C.
