fa13d3f4f3 build-remote.pl: Fix building multiple output derivations
We were importing paths without sorting them topologically, leading to
"path is not valid" errors.

a5c6347ff0 build-remote.pl: Use ‘nix-store --serve’ on the remote side
This makes things more efficient (we don't need to use an SSH master
connection, and we only start a single remote process) and gets rid of
locking issues (the remote nix-store process will keep inputs and
outputs locked as long as they're needed).

It also makes it more or less secure to connect directly to the root
account on the build machine, using a forced command
(e.g. ‘command="nix-store --serve --write"’). This bypasses the Nix
daemon and is therefore more efficient.

Also, don't call nix-store to import the output paths.

7bb632b024 nix-copy-closure -s: Do substitutions via ‘nix-store --serve’
This means we no longer need an SSH master connection, since we only
execute a single command on the remote host.

04170d06bf nix-copy-closure: Fix race condition
There is a long-standing race condition when copying a closure to a
remote machine, particularly affecting build-remote.pl: the client
first asks the remote machine which paths it already has, then copies
over the missing paths. If the garbage collector kicks in on the
remote machine between the first and second step, the already-present
paths may be deleted. The missing paths may then refer to deleted
paths, causing nix-copy-closure to fail. The client now performs both
steps using a single remote Nix call (using ‘nix-store --serve’),
locking all paths in the closure while querying.

I changed the --serve protocol a bit (getting rid of QueryCommand), so
this breaks the SSH substituter from older versions. But it was marked
experimental anyway.

Fixes #141.

2c3a8f787b Fix security hole in ‘nix-store --serve’
Since it didn't check that the path received from the client is a
store path, the client could dump any path in the file system.

5cd022d6c0 Add importNative primop
This can be used to import a dynamic shared object and return an
arbitrary value, including new primops. This can be used both to test
new primops without having to recompile nix every time, and to build
specialized primops that probably don't belong upstream (e.g. a function
that calls out to gpg to decrypt a nixops secret as-needed).

The imported function should initialize the Value & as needed. A single
import can define multiple values by creating an attrset or list, of
course.

An example initialization function might look like:

extern "C" void initialize(nix::EvalState & state, nix::Value & v)
{
    v.type = nix::tPrimOp;
    v.primOp = NEW nix::PrimOp(myFun, 1, state.symbols.create("myFun"));
}

Then `builtins.importNative ./example.so "initialize"` will evaluate to
the primop defined in the myFun function.

d8c061e044 Remove ExprBuiltin
It's slower than ExprVar since it doesn't compute a static
displacement. Since we're not using the throw primop in the
implementation of <...> anymore, it's also not really needed.
