New description:
Attached patches move `sage.rings.fraction_field.FractionField_generic` to
the new coercion model, and cythonize the
`sage.rings.fraction_field_element.FractionFieldElement` class. They also
allow homomorphisms of fraction fields to work, and make the
`random_element()` method of fractions fields return sensible results.
I will follow these up with specialized classes for rational functions.
The patches depend on #4278.
Since one of the patches renames a file (from *.py to *.pyx) it contains a
git style patch. Here are the lines you need in the .hgrc file:
