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.

Fix #1314 
Also, make nix-shell respect --option. (Previously it only passed it
along to nix-instantiate and nix-build.)

Fix #1380 
It lacked a backslash. Use a raw string and single quotes around PS1
to simplify this.

nix-shell: Overwrite environment variables 
Need to remember that std::map::insert() and emplace() don't overwrite
existing entries...

This fixes a regression relative to 1.11 that in particular triggers
in nested nix-shells.

Before:

  $ nativeBuildInputs=/foo nix-shell -p hello --run 'hello'
  build input /foo does not exist

After:

  $ nativeBuildInputs=/foo nix-shell -p hello --run 'hello'
  Hello, world!

3890de049d nix-shell: Fix 'nix-shell --command' doing nothing without TTY 
Regression from a5f2750e ("Fix early removal of rc-file for nix-shell").
The removal of BASH_ENV causes nothing to be executed by bash if it
detects itself in a non-interactive context. Instead, just
use the same condition used by bash to launch bash differently.

According to bash sources, the condition (stdin and stder both
must be TTYs) is specified by POSIX so this should be pretty
safe to rely on.

Fixes #1171 on master, needs a backport to the Perl code in 1.11.

018f884ffd nix-shell: Don't act interactive in shebangs 
I had observed that 'bash --rcfile' would do nothing in a
non-interactive context and cause nothing to be executed if a script
using nix-shell shebangs were run in a non-interactive context.

c698ec1f22 nix-shell: Fix 'nix-shell -i' 
The 'args' variable here is shadowing one in the outer scope and its
contents end up unused. This causes any '#! nix-shell' lines to
effectively be ignored. The intention here was to clear the args vector,
as far as I can tell (and it seems to work).

4de0639105 nix-shell: Fix $PATH handling in the impure case 
We were passing "p=$PATH" rather than "p=$PATH;", resulting in some
invalid shell code.

Also, construct a separate environment for the child rather than
overwriting the parent's.

a5f2750ebb Fix early removal of rc-file for nix-shell 
BASH_ENV causes all non-interactive shells called via eg. /etc/bashrc to
remove the rc-file before the main shell gets to run it. Completion
scripts will often do this. Fixes #976.

Adapted from and fixes #1034.
