nix dev-shell: Set IN_NIX_SHELL in the derivation
This ensures that stdenv / setup hooks take $IN_NIX_SHELL into
account. For example, stdenv only sets
NIX_SSL_CERT_FILE=/no-cert-file.crt if we're not in a shell.

nix dev-shell: Add --profile flag
This is useful to prevent the shell environment from being
garbage-collected.

Eelco Dolstra 2919c496ea nix dev-shell: Use 'provides.devShell' by default
Thus

  $ nix dev-shell

will now build the 'provides.devShell' attribute from the flake in the
current directory. If it doesn't exist, it falls back to
'provides.defaultPackage'.

Eelco Dolstra 2b8c63f303 Add 'nix dev-shell' and 'nix print-dev-env' command
'nix dev-shell' is intended to replace nix-shell. It supports flakes,
e.g.

  $ nix dev-shell nixpkgs:hello

starts a bash shell providing an environment for building 'hello'.

Like Lorri (and unlike nix-shell), it computes the build environment
by building a modified top-level derivation that writes the
environment after running $stdenv/setup to $out and exits. This
provides some caching, so it's faster than nix-shell in some cases
(especially for packages with lots of dependencies, where the setup
script takes a long time).

There also is a command 'nix print-dev-env' that prints out shell code
for setting up the build environment in an existing shell, e.g.

  $ . <(nix print-dev-env nixpkgs:hello)
