New description:
This ticket makes `Matrix` only inherit from `ModuleElement`.
Warning: it will cause practically all Cython files to be rebuilt.
See also #15215 (duplicate of this ticket).

Comment:
Given that this ticket has been open for more than seven years, it turned
out to be surprisingly straightforward. There is one small
simplification: `Matrix` used to have two identical methods `_mul_()` and
`__mul__()`, now it only needs `__mul__()`. On the other hand, new (but
very straightforward) `__pow__()` and `__div__()` methods were required.
