family of functions using the new nsdispatch(3) core. Remove arbitrary size limits when using the thread-safe versions. = Re-implement the traditional getpwent(3)/getgrent(3) functions on top of the thread-safe versions. = Update the on-disk format of the hashed version of the passwd(5) databases to allow for versioned entries. The legacy version is `3'. (Don't ask.) = Add support for version `4' entries in the passwd(5) database. Entries in this format are identical to version 3 entries except that all integers are stored as 32-bit integers in network byte order (big endian). = pwd_mkdb is updated to generate both version 3 and version 4 entries.
