Eelco Dolstra 6d30f9e6fe Explicitly make GC roots client sockets blocking 
On macOS / BSD, these sockets inherit the non-blocking flag of the
server soocket, which is not what we want.

Eelco Dolstra 35c98a59c5 Fix GC when there are cycles in the referrers graph 
(where "referrers" includes the reverse of derivation outputs and
derivers). Now we do a full traversal to look if we can reach any
root. If not, all paths reached can be deleted.

Eelco Dolstra 8614cf1334 Non-blocking garbage collector 
The garbage collector no longer blocks other processes from
adding/building store paths or adding GC roots. To prevent the
collector from deleting store paths just added by another process,
processes need to connect to the garbage collector via a Unix domain
socket to register new temporary roots.

Eelco Dolstra 4202a3bc4e UDSRemoteStore: Support the 'root' store parameter 
Useful when we're using a daemon with a chroot store, e.g.

  $ NIX_DAEMON_SOCKET_PATH=/tmp/chroot/nix/var/nix/daemon-socket/socket nix-daemon --store /tmp/chroot

Then the client can now connect with

  $ nix build --store unix:///tmp/chroot/nix/var/nix/daemon-socket/socket?root=/tmp/chroot nixpkgs#hello

build: fix sandboxing on darwin 
Starting ba87b08f85 getEnv now returns an
std::optional which means these getEnv() != "" conditions no longer happen
if the variables are not defined.

Eelco Dolstra bbe97dff8b Make the Store API more type-safe 
Most functions now take a StorePath argument rather than a Path (which
is just an alias for std::string). The StorePath constructor ensures
that the path is syntactically correct (i.e. it looks like
<store-dir>/<base32-hash>-<name>). Similarly, functions like
buildPaths() now take a StorePathWithOutputs, rather than abusing Path
by adding a '!<outputs>' suffix.

Note that the StorePath type is implemented in Rust. This involves
some hackery to allow Rust values to be used directly in C++, via a
helper type whose destructor calls the Rust type's drop()
function. The main issue is the dynamic nature of C++ move semantics:
after we have moved a Rust value, we should not call the drop function
on the original value. So when we move a value, we set the original
value to bitwise zero, and the destructor only calls drop() if the
value is not bitwise zero. This should be sufficient for most types.

Also lots of minor cleanups to the C++ API to make it more modern
(e.g. using std::optional and std::string_view in some places).
