    Add recallocarray() and freezero() from OpenBSD · 01f0d1ea
    Faidon Liambotis authored
    Add recallocarray(), introduced in OpenBSD 6.1, and freezero(),
    introduced in OpenBSD 6.2. The former is imported as-is from OpenBSD,
    while the latter is the non-malloc-internal branch of the same code (and
    also the OpenSSH portable variant).
    
    Both of these originated in OpenBSD, but have also been implemented by
    IllumOS, cf. https://www.illumos.org/issues/8546
    
    Documentation for these functions is in malloc(3) upstream, the relevant
    parts of which were previously imported in reallocarray(3bsd). Update
    reallocarray(3bsd) with the changes that were introduced since, and add
    the relevant bits for recallocarray() and freezero(), plus aliases.
