#10752: Matrix pivots are cached, should be immutable

Oops:
{{{
sage: A=matrix(ZZ, 2, range(4))
sage: p = A.pivots(); p
[0, 1]
sage: p.append(652)
sage: A.pivots()
[0, 1, 652]
}}}
I'd imagine returning a tuple rather than a list would be the best
approach. Though how much chaos will ensue is not clear.
