Modify pw_copy: - if pw is NULL and oldpw is not NULL then the oldpw is deleted - if pw->pw_name != oldpw->pw_name but pw->pw_uid == oldpw->pw_uid then it renames the user add new gr_* functions so now gr_util API is similar to pw_util API, this allow to manipulate groups in a safe way. Add new pw_make_v7 to make a passwd line (in v7 format) out of a struct passwd Approved by: des (mentor)

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. Reviewed by: arundel

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. PR: bin/146205 Reviewed by: arundel

Bring in missing headers and primitive type declarations into to make it work when included by itself. r200035 (ed): Make work when included by itself. There are several reasons why it didn't work: - It was missing for __BEGIN_DECLS. - It uses various primitive types that were not declared. r219344 (pjd): expand_number() needs uint64_t, declare it here if not already declared.
