Subject: [PATCH 036/128] pythonPackages.xgboost: fix build

The setup.py of `python-package` contains some path resolution magic to
find `libxgboost.so` which is needed for the python API.

Unfortunately the code is incompatible with Nix as it isn't compatible
with the store-based structure for each package and tries to express the
location of the shared object with relative paths.

The detection in `setup.py` and `xgboost/libpath.py` has been either
removed entirely or patched to link to the proper store path of the
`libxgboost` build input.

See https://hydra.nixos.org/build/77702715 for further reference.

Subject: [PATCH 039/128] vim-plugins: update (2018-07-19)

Moved 'dhall-vim' to match order in vim-plugin-names,
so diff'ing against generated expressions is easier.

There's a "vim-nix" update in here! :)

The updated version brings selective whitelisting, i.e. when some CVEs
of a package are whitelisted and others are not, only the new CVEs are
reported.
