New description:
As indicated in #9326, it is desirable for fans and cones associated to
toric varieties to know these toric varieties. The framework for such an
association was already designed (with a view towards morphisms), this
patch puts it to work.

Comment:
Changed line 2232 in `fan` (I missed explicit setting of the ambient fan).
I have added a doctest for the above case into
`Fan_of_toric_variety.__init__`.
