#10070: make heaviside and step play nicely together.

-------------------------+--------------------------------------------------
The heaviside built-in function and the step symbolic method are not the
same at zero.
{{{
sage: heaviside(0)
heaviside(0)
sage: SR(0).step()
1/2
}}}
And the documentation seems to indicate that `heaviside` should be
undefined (?) at zero, though it's not definitive.
In addition to reconciling these, we should probably unify notation or
something.
