9f36610f9e libc: provide some bounds-checking through reallocarray(3).
reallocarray(3) is a non portable extension that originated in OpenBSD.
Given that it is already in FreeBSD's libc it is useful for the cases
where reallocation involves a multiplication.

88f919d683 The argument corresponding to %zn is supposed to be an ssize_t *, not

07bed96bd3 Factor out the code that builds the argument table. We don't need separate
normal and wide character versions of it.

No functional change.

2591efccfa Reduce the level of duplication between vfprintf() and vfwprintf()
by moving the positional argument handling code to a new file,
printf-pos.c, and moving common definitions to printflocal.h.
No functional change intended.
