7d14df1a2d Add support for IEE/IEC (and now also SI) power of two notions of
prefixes (Ki, Mi, Gi...) for humanize_number(3).

Note that applications has to pass HN_IEC_PREFIXES to use this
feature for backward compatibility reasons.

a699e14f45 humanize_number(3) multiply the input number by 100, which could cause an
integer overflow when the input is very large (for example, 100 Pi would
become about 10 Ei which exceeded signed int64_t).

Solve this issue by splitting the division into two parts and avoid the
multiplication.

6044f112a6 Merge changes from NetBSD on humanize_number.c, 1.8 -> 1.13
Significant changes:
- rev. 1.11: Use PRId64 instead of a cast to long long and %lld to print
an int64_t.
- rev. 1.12: Fix a bug that humanize_number() produces "1000" where it
should be "1.0G" or "1.0M".  The bug reported by Greg Troxel.
