lib: add bitmap_{from,to}_arr64
Manipulating 64-bit arrays with bitmap functions is potentially dangerous
because on 32-bit BE machines the order of halfwords doesn't match.
Another issue is that compiler may throw a warning about out-of-boundary
access.
This patch adds bitmap_{from,to}_arr64 functions in addition to existing
bitmap_{from,to}_arr32.
