nix run: Fix chroot execution
...
Running "nix run" with a diverted store, e.g.
$ nix run --store local?root=/tmp/nix nixpkgs.hello
stopped working when Nix became multithreaded, because
unshare(CLONE_NEWUSER) doesn't work in multithreaded processes. The
obvious solution is to terminate all other threads first, but 1) there
is no way to terminate Boehm GC marker threads; and 2) it appears that
the kernel has a race where unshare(CLONE_NEWUSER) will still fail for
some indeterminate amount of time after joining other threads.
So instead, "nix run" will now exec() a single-threaded helper ("nix
__run_in_chroot") that performs the actual unshare()/chroot()/exec().

Make TunnelLogger thread-safe
...
Now that we use threads in lots of places, it's possible for
TunnelLogger::log() to be called asynchronously from other threads
than the main loop. So we need to ensure that STDERR_NEXT messages
don't clobber other messages.

The function 'builtins.split' takes a POSIX extended regular expression

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";
