This patch will add "stronger properties" -line to seealso-block of
is_constructible_by_doublings(). Not very nice, but I can't invent
better way. Ideas are welcome.

What about "not"-implications? If a lattice ''is'' simple, it ''is not''
doubling constructible. How to say that, or to say nothing?

Follow-up to #22806 and #22896: we should stop using the deprecated
files `cysignals/memory.pxi` and `cysignals/signals.pxi`.

Given the large number of files which need to be changed, this is done
in parts.

The flint library has a builtin type for rational matrices:
`fmpq_mat_t`. This ticket proposes to replace the current array of
`mpq_t` wrapped by `Matrix_rational_dense` in favor of `fmpq_mat_t`.

Using almost the same code from ReflectionGroup and adding it to
CoxeterMatrixGroup in order to allow constructing a weight space
permutahedron in a Coxeter matrix group and not just in reflection
groups.

Right now we can only get the Bruhat graph of Weyl groups even though we
can do the same thing for Coxeter Groups. I plan on moving bruhat_graph
from the WeylGroups class in combinat/root_system to the category of
Coxeter groups. This will keep WeylGroup having the method, but expand
it to Coxter groups.

Additionally, it would be natural to not require two elements to find a
the graph between them. So instead, if the group is finite, we'll allow
the calling of bruhat_graph() which will bring back the entire graph.

Added a method `bounded_affine_permutation` to permutation, which
outputs a partial permutation representing the bounded affine
permutation of a real matrix.

Little file, in which I did a pep8 and code cleanup.

Maybe this should just be deprecated instead ? It is only used twice, by
permutations and binary trees.
