Eelco Dolstra f738cd4d97 More Rust FFI adventures
We can now convert Rust Errors to C++ exceptions. At the Rust->C++ FFI
boundary, Result<T, Error> will cause Error to be converted to and
thrown as a C++ exception.

Eelco Dolstra 045708db43 Make <nix/unpack-channel.nix> a builtin builder
This was the last function using a shell script, so this allows us to
get rid of tar, coreutils, bash etc.

Fix Brotli decompression in 'nix log'
This didn't work anymore since decompression was only done in the
non-coroutine case.

Decompressors are now sinks, just like compressors.

Also fixed a bug in bzip2 API handling (we have to handle BZ_RUN_OK
rather than BZ_OK), which we didn't notice because there was a missing
'throw':

  if (ret != BZ_OK)
      CompressionError("error while compressing bzip2 file");

Make <nix/fetchurl.nix> run in constant memory
E.g.

  nix-build --store ~/my-nix/ -E 'import <nix/fetchurl.nix> { url = https://cache.nixos.org/nar/0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv.nar.xz; sha256 = "0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv"; }'

now runs in 17 MiB (was 70 MiB), while

  nix-build --store ~/my-nix/ -E 'import <nix/fetchurl.nix> { url = https://cache.nixos.org/nar/0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv.nar.xz; sha256 = "0d2fxljdih3nc5dqx41hjzic3141ajil94m8kdbpryq569dpsbvb"; unpack = true; }'

runs in 17 MiB (was 346 MiB).

<nix/buildenv.nix>: Skip non-directory top-level paths
Fixes https://github.com/NixOS/nix/issues/1934 (at least the "error:
opening directory '/nix/store/...-linux-config-4.4.14': Not a
directory" issue).
