    Convert code to use FSmallocarray() & FSreallocarray()
    
    Provides automatic integer overflow checking in allocation size calculations
    (Though we already have explicit checks before using values provided
     over the protocol in calculations, so many were already manually checked.)

commit 4a1d0977dbb6eb960ca4deedba90940bcaeecefb
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
