Eelco Dolstra b89b6b2a7b Add function callPackagesWith
This is like callPackageWith, except that it expects the supplied
function to return a *set* of packages. It will then make the
individual packages overridable.

Eelco Dolstra 314e8e49ec Remove deepOverride
It's unused, and also a bad idea: because it recursively recomputes
every function argument and there is no sharing, you can get an
exponential (?) blowup in evaluation time. For example, evaluating
‘linuxPackages.kernel’ takes 0.09s and ~13 MiB, but evaluating
‘linuxPackages.kernel.deepOverride {}’ takes 3.6s and ~305 MiB.

Eelco Dolstra 0461f35894 Rename scrubDrv -> hydraJob and make it more effective
It now strictly evaluates all remaining attributes, preventing
unevaluated thunks that cannot be garbage-collected. It's also applied
to all jobs in Nixpkgs' release.nix.

This reduces hydra-eval-jobs' memory consumption on the 14.12
release-combined jobset from 5.1 GB to 2.0 GB.

Shea Levy 8921a8f53b Revert "Revert "mkOverridable: Use functors to allow overridable functions""
Original commit was reverted due to using features from a newer nix than
hydra had, hydra has since been updated

This reverts commit 07e726c85c.

Eelco Dolstra 97220c973f Replace hasAttr/getAttr calls with the ? and . operators
For NixOS evaluation, this gives a ~21% reduction in the number of
values allocated and a ~4% speedup. It's also more readable.
