New description:
Rather than defining libraries in `module_list.py` or in `.pyx` files, we
should add them to the `.pxd` files where the declarations are.
In this branch, we do this as proof-of-concept for `pari` and `gmp`. Other
tickets can be opened later for other libraries.
One annoying part is that the order of libraries is not defined, so we
need to manually re-order them using one global library order. Since the
order of libraries currently specified in `src/module_list.py` is far from
a DAG, many extensions will be compiled with a different library order
than before.
To clean up, we also remove the explicit mention of `stdc++` for `c++`
code (which is automatically added anyway).
-----
These are all modules where the list of libraries was actually changed:
These were probably underlinked before:
* `sage/rings/polynomial/pbori`: added `gmp`
* `sage/rings/rational`: added `pari`
* `sage/rings/real_arb` (optional): added `gmp`
This branch adds `gmp` for all modules where bitsets are used. Some bitset
functions require GMP, others do not. These modules were only using the
ones not implemented using GMP:
* `sage/combinat/debruijn_sequence`: added `gmp`
* `sage/combinat/words/word_char`: added `gmp`
* `sage/graphs/base/static_sparse_backend`: added `gmp`
* `sage/graphs/weakly_chordal`: added `gmp`
Modules using the Sage/PARI interface but not directly using PARI will now
link against `pari`. Strictly speaking, this is a bug but it's hard to
avoid:
* `sage/rings/real_double`: added `pari`
Unused libraries are removed:
* `sage/combinat/partitions`: removed `gmp` and `mpfr`
* `sage/graphs/graph_generators_pyx`: removed `gmp`
* `sage/groups/semimonomial_transformations/semimonomial_transformation`:
removed `gmp`
* `sage/modular/modsym/p1list`: removed `gmp`
-----
We need 2 patches to upstream Cython to fix dependency handling:
* [https://github.com/cython/cython/pull/381]
* [https://github.com/cython/cython/pull/392]
