Restore parent mount namespace before executing a child process 
This ensures that they can't write to /nix/store. Fixes #2535.

Move EvalState from the stack to the heap 
EvalState contains a few counters (e.g. nrValues) that increase
quickly enough that they end up being interpreted as pointers by the
garbage collector. Moving it to the heap makes them invisible to the
garbage collector.

This reduces the max RSS doing 100 evaluations of
nixos.tests.firefox.x86_64-linux.drvPath from 455 MiB to 292 MiB.

Note: ideally, allocations would be much further up in the 64-bit
address space to reduce the odds of an integer being misinterpreted as
a pointer. Maybe we can use some linker magic to move the .bss segment
to a higher address.

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

Replace readline by linenoise 
Using linenoise avoids a license compatibility issue (#1356), is a lot
smaller and doesn't pull in ncurses.
