Don't register invalid paths as GC roots
Unfortunately this doesn't work. Maybe we should keep separate roots
for each path.

Make flake input fetching lazy
As long as the flake input is locked, it is now only fetched when it
is evaluated (e.g. "nixpkgs" is fetched when
"inputs.nixpkgs.<something>" is evaluated).

This required adding an "id" attribute to the members of "inputs" in
lockfiles, e.g.

  "inputs": {
    "nixpkgs/release-19.03": {
      "id": "nixpkgs",
      "inputs": {},
      "narHash": "sha256-eYtxncIMFVmOHaHBtTdPGcs/AnJqKqA6tHCm0UmPYQU=",
      "nonFlakeInputs": {},
      "uri": "github:edolstra/nixpkgs/e9d5882bb861dc48f8d46960e7c820efdbe8f9c1"
    }
  }

because the flake ID needs to be known beforehand to construct the
"inputs" attrset.

Fixes #2913.

Add 'nix app' command
This is like 'nix run', except that the command to execute is defined
in a flake output, e.g.

  defaultApp = {
    type = "app";
    program = "${packages.blender_2_80}/bin/blender";
  };

Thus you can do

  $ nix app blender-bin

to start Blender from the 'blender-bin' flake.

In the future, we can extend this with sandboxing. (For example we
would want to be able to specify that Blender should not have network
access by default and should only have access to certain paths in the
user's home directory.)

Automatically determine subdir for path flakes
This means that in a flake in a subdirectory of a Git repo, you can
now do

  $ nix build

rather than the inconvenient

  $ nix build ../..?dir=foo/bar

Allow bare flakerefs as installables
So now

  $ nix build blender-bin

works and builds the default package from that flake. You don't need
to add a colon at the end anymore.

nix flake info --json: List the "provides"
It also lists the contents of "checks" and "packages".

For example:

  $ nix flake info --json | jq

    "description": "The purely functional package manager",
    "epoch": 2019,
    "id": "nix",
    "lastModified": 1559161142,
    "path": "/nix/store/2w2qla8735dbxah8gai8r1nsbf5x4f5d-source",
    "provides": {

        "binaryTarball": {},
        "nix-copy-closure": {},
        "perlBindings": {},
        "remoteBuilds": {},
        "setuid": {}
      },
      "defaultPackage": {},
      "devShell": {},
      "hydraJobs": {},
      "packages": {
        "nix": {},
        "nix-perl-bindings": {}
      }
    },

    "revision": "8cb24e04e8b6cc60e2504733afe78e0eadafcd98",
    "uri": "/home/eelco/Dev/nix"
  }

Fixes #2820.

Hack: Use legacyPackages from Nixpkgs
Nixpkgs doesn't provide a clean "packages" set yet, so until that's
the case, look for packages in "legacyPackages" as well.

Add date of last commit to SourceInfo
This is primarily useful for version string generation, where we need
a monotonically increasing number. The revcount is the preferred thing
to use, but isn't available for GitHub flakes (since it requires
fetching the entire history). The last commit timestamp OTOH can be
extracted from GitHub tarballs.
