commit 3ff95c472abe8eb8fe1ccda5cd40d99407f1f9a4
Author: Alan Coopersmith <alan.coopersmith at oracle.com>

    Import reallocarray() from libX11 (originally from OpenBSD)
    
    Wrapper for realloc() that checks for overflow when multiplying
    arguments together, so we don't have to add overflow checks to
    every single call.  For documentation on usage, see:
    http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man3/calloc.3
