...
Before:
nix-repl> :l <nixpkgs>
nix-repl> lib.matchAttrs { foo = "bar"; } { bar = "bas"; }
error: undefined variable ‘length’ at "/home/benley/nix/nixpkgs/lib/attrsets.nix":317:10
After:
nix-repl> :l <nixpkgs>
nix-repl> lib.matchAttrs { foo = "bar"; } { bar = "bas"; }
false

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.

Remove backward-compatible implementations of some primops
...
Nixpkgs requires at least Nix 1.2 anyway, so these are now useless.

Keep position information for option declarations and definitions
...
Also, when an option definition fails to type-check, print the file
name of the module in which the offending definition occurs, e.g.
error: user-thrown exception: The option value `boot.loader.grub.version' in `/etc/nixos/configuration.nix' is not a integer.
