Summary:
Pull Request resolved: https://github.com/facebookresearch/faiss/pull/2582
A few more or less cosmetic improvements
* Index::idx_t was in the Index object, which does not make much sense, this diff moves it to faiss::idx_t
* replace multiprocessing.dummy with multiprocessing.pool
* add Alexandr as a core contributor of Faiss in the README ;-)
```
for i in $( find . -name \*.cu -o -name \*.cuh -o -name \*.h -o -name \*.cpp ) ; do
sed -i s/Index::idx_t/idx_t/ $i
done
```
For the fbcode deps:
```
for i in $( fbgs Index::idx_t --exclude fbcode/faiss -l ) ; do
sed -i s/Index::idx_t/idx_t/ $i
done
```

Summary:
Pull Request resolved: https://github.com/facebookresearch/faiss/pull/2483
This diff changes the following:
1. all search functions now take a `SearchParameters` argument that overrides the internal search parameters
2. the default implementation for most classes throws when the params argument is non-nullptr / non-None
3. the IndexIVF and IndexHNSW classes have functioning SearchPArameters
4. the SearchParameters includes an IDSelector that can search only in a subset of the index based on a defined subset of ids
There is also some refactoring: the IDSelector was moved to its own .h/.cpp and python/__init__.py is spit in parts.
The diff is quite bulky because the search function prototypes need to be changed in all index classes.
Things to fix in subsequent diffs:
- support SearchParameters for more index types (Flat variants)
- better sub-object ownership for SearchParams (with std::unique_ptr?)
- special handling of IDSelectorRange to make it faster
