New description:
The Parma Polyhedra Library (ppl) is for many workloads the fastest
library for polyhedral computations. It is also high-quality code, for
example GCC uses it (optionally) to optimize loops.
* ppl has already been widely tested on a multitude of platforms.
* Native C++ with a pure C interface.
* Contains a huge testsuite _and_ passes its own testsuite (in contrast
to some other polydedral library that shall remain unnamed)

My plan is to
1. Create a PPL spkg.
2. Write a Cython interface.
3. Base `sage.geometry.cone.Cone` on PPL instead of `Polyhedron/cddlib`
4. Split `sage.geometry.polyhedra.Polyhedron` into an abstract base
class and derived classes that use different polyhedral computation
libraries.
Current status:
1. Spkg can be found here:
http://www.stp.dias.ie/~vbraun/Sage/spkg/ppl-0.11.2.spkg
2. My cython wrapper for PPL is attached. It has full doctest coverage
and any invalid input is caught and raises `ValueError`.
3. Is split off into trac #10140.
For convenience I mirrored the reference manual page here:

Comment(by jdemeyer):
Some administrative issues:
1. Now that #9433 is merged, changes to `spkg/install` and
`spkg/standard/deps` should be made using `hg export tip` (producing an
actual HG changeset for the `sage_root` repository).
2. Please state clearly which patches have to be applied where.
