Convert a `bslma::Allocator` pointer to an `allocator` object that forwards allocation calls to the object pointed to by the specified `mechanism`. If `mechanism` is 0, then the currently installed default allocator is used instead. Postcondition: ` this‐>mechanism() == bslma::Default::allocator(mechanism); `
