daemon: Flush the sink upon 'exportPath' errors.
Prior to this change, errors such as wrong permissions on
/etc/guix/signing-key.sec would give:

  guix-daemon: nix/libutil/serialise.cc:15: virtual nix::BufferedSink::~BufferedSink(): Assertion `!bufPos' failed.

This patch correctly propagates the error to the client and thus changes
that to:

  error: build failed: file `/etc/guix/signing-key.sec' should be secret (inaccessible to everybody else)!

* nix/nix-daemon/nix-daemon.cc (performOp): Wrap 'exportPath' call in
'try' block.

e134baae77 daemon: optimizePath: Detect some .links corruptions.
If automatic store optimisation is enabled, and a hard-linked file in
the store gets corrupted, then the corresponding .links entry will
also be corrupted. In that case, trying to repair with --repair or
--repair-path won't work, because the new "good" file will be replaced
by a hard link to the corrupted file. We can catch most of these cases
by doing a sanity-check on the file sizes.

Note that this means we may have a non-functional /bin/sh in the

packages don't rely on /bin/sh though.

    Preserve supplementary groups of build users

    The following patch is an attempt to address this bug (see
    <http://bugs.gnu.org/18994>) by preserving the supplementary groups of
    build users in the build environment.

    In practice, I would expect that supplementary groups would contain only
    one or two groups: the build users group, and possibly the “kvm” group.

    Allow substitutes for builds that have preferLocalBuild set

    Not substituting builds with "preferLocalBuild = true" was a bad idea,
    because it didn't take the cost of dependencies into account. For
    instance, if we can't substitute a fetchgit call, then we have to
    download/build git and all its dependencies.

    Partially reverts 5558652709f27e8a887580b77b93c705659d7a4b and adds a
    new derivation attribute "allowSubstitutes" to specify whether a
    derivation may be substituted.
