nix optimise-store: Add 
This replaces "nix-store --optimise". Main difference is that it has a
progress indicator.

Progress indicator: Unify "copying" and "substituting" 
They're the same thing after all.

Example:

  $ nix build --store local?root=/tmp/nix nixpkgs.firefox-unwrapped
  [0/1 built, 49/98 copied, 16.3/92.8 MiB DL, 55.8/309.2 MiB copied] downloading 'https://cache.nixos.org/nar/0pl9li1jigcj2dany47hpmn0r3r48wc4nz48v5mqhh426lgz3bz6.nar.xz'

Improve substitution progress indicator 
E.g.

  $ nix build --store local?root=/tmp/nix nixpkgs.firefox-unwrapped

Nicolas B. Pierron b8867a0239 Add builtins.string function. 
The function 'builtins.split' takes a POSIX extended regular expression
and an arbitrary string. It returns a list of non-matching substring
interleaved by lists of matched groups of the regular expression.

```nix
with builtins;
assert split "(a)b" "abc"      == [ "" [ "a" ] "c" ];
assert split "([ac])" "abc"    == [ "" [ "a" ] "b" [ "c" ] "" ];
assert split "(a)|(c)" "abc"   == [ "" [ "a" null ] "b" [ null "c" ] "" ];
assert split "([[:upper:]]+)" "  FOO   "
                               == [ "  " [ "FOO" ] "   " ];
```

builtins.fetchgit: Support specifying commit hashes 
This adds an argument "rev" specififying the Git commit hash. The
existing argument "rev" is renamed to "ref". The default value for
"ref" is "master". When specifying a hash, it's necessary to specify a
ref since we're not cloning the entire repository but only fetching a
specific ref.

Example usage:

  builtins.fetchgit {
    url = https://github.com/NixOS/nixpkgs.git;
    ref = "release-16.03";
    rev = "c1c0484041ab6f9c6858c8ade80a8477c9ae4442";
  };

builtins.fetchgit: Respect tarball-ttl 
I.e. if the local ref is more recent than tarball-ttl seconds, then
don't check the remote.

builtins.fetchgit: Cache hash -> store path mappings

nix search: Add a cache 
The package list is now cached in
~/.cache/nix/package-search.json. This gives a substantial speedup to
"nix search" queries. For example (on an SSD):

First run: (no package search cache, cold page cache)

  $ time nix search blender
  Attribute name: nixpkgs.blender
  Package name: blender
  Version: 2.78c
  Description: 3D Creation/Animation/Publishing System

  real    0m6.516s

Second run: (package search cache populated)

  $ time nix search blender
  Attribute name: nixpkgs.blender
  Package name: blender
  Version: 2.78c
  Description: 3D Creation/Animation/Publishing System

  real    0m0.143s

nix-build/nix-shell: Eliminate call to nix-instantiate / nix-store 
Note that this removes the need for a derivation symlink, so the
--drv-path and --add-drv-link flags now do nothing.

nix-shell: Use bashInteractive from <nixpkgs> 
This adds about 0.1s to nix-shell runtime in the case where
bashInteractive already exists.

nix search: Ignore top-level eval errors 
$NIX_PATH may contain elements that don't evaluate to an attrset (like
"nixos-config"), so ignore those.

Always use base-16 for hashed mirror lookups 
In particular, don't use base-64, which we don't support. (We do have
base-32 redirects for hysterical reasons.)

Also, add a test for the hashed mirror feature.

Avoid a call to derivationFromPath() 
This doesn't work in read-only mode, ensuring that operations like

  nix path-info --store https://cache.nixos.org -S nixpkgs.hello

(asking for the closure size of nixpkgs.hello in cache.nixos.org) work
when nixpkgs.hello doesn't exist in the local store.
