The libxalloc was reincarnated long ago in a separate utility library.
It did a good job help make ezstream have robust memory management years ago,
but now it's time to move on and get back to basics.
The replacement introduces reallocarray(), which is an overflow-checking
alternative to both malloc (NULL ptr) and realloc().
There are a few benefits to this, but the main reason is consistency and me
completely understanding what's going on. Regressions are not expected, but
wouldn't surprise either ... this needs lots of testing.
