[io][HDF5File] benefit when possible of the "locking" parameter from h5py

will be applied only when HDF5 >= 1.12.1 or 1.10.x >= 1.10.7 Old 'API' from environment variable will still work.

changed milestone to %0.7

requested review from @paleo

Good idea. Although I find the calc_hexversion from silx unnecessarily abstruse - perhaps we can use something like

from packaging.version import parse as parse_version
    recommendations = [
        ("h5py", h5py_version.version, "3.0"),
        ("libhdf5", h5py_version.hdf5_version, "1.10.6")
    ]
    for what, current_version, recommended_version in recommendations:
        msg = str("You are using %s %s. Please consider upgrading to %s >= %s. "
            % (what, current_version, what, recommended_version)
        )
        if parse_version(current_version) < parse_version(recommended_version):
            logger.warning(msg)

packaging is not built-in, but it's required by packages like pytest or Sphinx, so it's certainly installed anyway.

Alright, not sure we gain in clarity by switching to packaging.version :-/
