PMDK Version 1.10

This release introduces a new stable PMDK library, libpmem2, which
is the next major release of libpmem.
This library has an entirely new, but familiar API that addresses many
shortcomings of the previous version while retaining all of its
functionality. To learn more, see https://pmem.io/pmdk/libpmem2/ or
libpmem2(7).
The old library, libpmem, is still going to be maintained for the
foreseeable future, but we'd like to encourage any new applications to
leverage libpmem2.
