Dennis Wölfing 2e0bbbfbf9 Add reallocarray function 
The reallocarray function is an extension from OpenBSD.  It is an
integer-overflow-safe replacement for realloc(p, X*Y) and
malloc(X*Y) (realloc(NULL, X*Y)).  It can therefore help in preventing
certain security issues in code.

This is an updated version of a patch originally submitted by Rüdiger
Sonderfeld in May 2014 [1].

Checked on i686-linux-gnu and x86_64-linux-gnu.

[1] <https://sourceware.org/ml/libc-alpha/2014-05/msg00481.html>.
