Explicitly pass group generator to mul_double_nonct() from EC_POINT_mul().

EC_POINT_mul() has a complex multi-use interface - there are effectively
three different ways it will behave, depending on which arguments are NULL.
In the case where we compute g_scalar * generator + p_scalar * point, the
mul_double_nonct() function pointer is called, however only g_scalar,
p_scalar and point are passed - it is expected that the lower level
implementation (in this case ec_wnaf_mul()) will use the generator from
the group.

Change mul_double_nonct(), ec_mul_double_nonct() and ec_wnaf_mul() so that
they take scalar1, point1, scalar2 and point2. This removes all knowledge
of g_scalar and the generator from the multiplication code, keeping it
limited to EC_POINT_mul(). While here also consistently pass scalar then
point, rather than a mix of scalar/point and point/scalar.
