Reduce casts of HDcalloc()/HDmalloc() that -Wc++-compat required.
Reduce gratuitous casts---e.g., (size_t)1. Use the right format string for a pointer. In the H5C sanity checks, change a "size increase" variable from ssize_t (too narrow) to int64_t (wide enough). Parenthesize every appearance of `storage` in the macro `H5D_CHUNK_STORAGE_INDEX_CHK(storage)` so that you can pass in an expression like &sc and it works properly. Disallow re-assignment of the `dset` parameter to H5D__chunk_init() because it helped assure me that it's safe to replace the repeating expression `&dset->shared->layout.storage.u.chunk` with `sc` throughout. Replace lengthy expressions such as `&dset->shared->layout.storage.u.chunk` with `sc` throughout several functions in H5Dchunk.c ISTR that the compiler warned that `sc` was declared but unused in a couple of functions, and then I found that `sc` could be used in many places. Maybe the disused `sc` appeared because a bunch of code was copied and pasted, I don't know. Anyway, it's a lot tighter code now that I use `sc`. In H5D__chunk_update_old_edge_chunks() and H5D__chunk_delete() I actually expand `sc` and another temporary variable, `pline`, because they're used only in !defined(NDEBUG) code. This squashes unused-variable warnings in the defined(NDEBUG) configuration. Don't drop the `volatile` qualification with a cast in tools/src/h5import/h5import.c.
