This patch implements pseudo-Conway polynomials, which are used to enable
coercion between finite fields. This has been split off from #8335, and
is a dependency of that ticket.

Comment:
Reasons for status change to needs_info:
- the 'tree' terminology (see
http://trac.sagemath.org/ticket/14958#comment:6); I think that
`PseudoConwayPolyTree` should be changed to `PseudoConwayLattice` or
something similar.
- during Sage Days 51, Jenny Cooley found a paper claiming that there is a
mistake in one of the algorithms in the article of Heath and Loehr cited
in the code. We should check that the error is not in this patch.
