The successful states used in these two places in the code were slightly
different. Should they be the same list?

Eelco Dolstra 5332c439d0 InstallableFlake: Show all possible attribute names 
E.g.

  $ nix run nixpkgs#hello
  error: --- Error ---------- nix
  flake 'flake:nixpkgs' does not provide attribute 'apps.x86_64-linux.hello' or 'hello'

instead of

  $ nix run nixpkgs#hello
  error: --- Error ---------- nix

regnat 56d75bf4fc Reserve the __contentAddressed derivation parameter 
Not implementing anything here, just throwing an error if a derivation
sets `__contentAddressed = true` without
`--experimental-features content-addressed-paths`
(and also with it as there's nothing implemented yet)

Eelco Dolstra 759947bf72 StorePath: Rewrite in C++ 
On nix-env -qa -f '<nixpkgs>', this reduces maximum RSS by 20970 KiB
and runtime by 0.8%. This is mostly because we're not parsing the hash
part as a hash anymore (just validating that it consists of base-32
characters).

Also, replace storePathToHash() by StorePath::hashPart().

  error: --- Error ---------------------------------------------------- nix

Eelco Dolstra 045b07200c Remove Store::queryDerivationOutputNames() 
This function was used in only one place, where it could easily be
replaced by readDerivation() since it's not
performance-critical. (This function appears to have been modelled
after queryDerivationOutputs(), which exists only to make the garbage
collector faster.)

Eelco Dolstra 0c62b4ad0f Represent 'follows' inputs explicitly in the lock file 
This fixes an issue where lockfile generation was not idempotent:
after updating a lockfile, a "follows" node would end up pointing to a
new copy of the node, rather than to the original node.

Matthew Bauer 19aa892f20 Support empty hash in fetchers 
fetchTarball, fetchTree, and fetchGit all have *optional* hash attrs.
This means that we need to be careful with what we allow to avoid
accidentally making these defaults. When ‘hash = ""’ we assume the
empty hash is wanted.

follow up of https://github.com/NixOS/nix/pull/3544

This allows hash="" so that it can be used for debugging purposes. For

Eelco Dolstra 810b2c6a48 nix flake init: Add a '--template' flag 
The initial contents of the flake is specified by the
'templates.<name>' or 'defaultTemplate' output of another flake. E.g.

  outputs = { self }: {

    templates = {

      nixos-container = {
        path = ./nixos-container;
        description = "An example of a NixOS container";
      };

    };

  };

allows

  $ nix flake init -t templates#nixos-container

Also add a command 'nix flake new', which is identical to 'nix flake
init' except that it initializes a specified directory rather than the
current directory.

John Ericson d73dbc8e4c Remove hashingWithUnknownAlgoExits 
A valid hash type must be provided now. The hash itself can still be
invalid, but that doesn't cause an `abort()`.

John Ericson 450dcf2c1b Remove HashType::Unknown 
Instead, `Hash` uses `std::optional<HashType>`. In the future, we may
also make `Hash` itself require a known hash type, encoraging people to
use `std::optional<Hash>` instead.

Matthew Kenigsberg ff1320b850 fetchOrSubstituteTree improvements 
Caches tree in addition to lockedRef, and explicitly writes out the logic for different combinations of cached/uncached flakes and indirect/resolved/locked flakes. This eliminates uneccessary calls to lookupInFlakeCache, fetchTree, maybeLookupFlake, and flakeCache.push_back

Nikola Knezevic fb38459d6e Ensure we restrict refspec interpretation while fetching 
As `git fetch` may chose to interpret refspec to it's liking, ensure that we
only pass refs that begin with `refs/` as is, otherwise, prepend them with
`refs/heads`. Otherwise, branches named `heads/foo` (I know it's bad, but it's
allowed), would be fetched as `foo`, instead of `heads/foo`.

Nikola Knezevic 77007d4eab Improve ref validity checking in fetchGit 
The previous regex was too strict and did not match what git was allowing. It
could lead to `fetchGit` not accepting valid branch names, even though they
exist in a repository (for example, branch names containing `/`, which are
pretty standard, like `release/1.0` branches).

The new regex defines what a branch name should **NOT** contain. It takes the
definitions from `refs.c` in https://github.com/git/git and `git help
check-ref-format` pages.

This change also introduces a test for ref name validity checking, which
compares the result from Nix with the result of `git check-ref-format --branch`.
