Add reallocarray function

Browse Source 
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.

The @code{reallocarray} function changes the size of the block whose address

@comment The following is no longer true with the new malloc.

In several allocation implementations, making a block smaller sometimes
necessitates copying it, so it can fail if no other space is available.
