Subject: * Get `nix-push' working again.  It now uses Nix/Fix to create Nix  
 archives (using the package in corepkgs/nar). * queryPathByHash ->
 expandHash, and it takes an argument specifying   the target path (which may
 be empty). * Install the core Fix packages in $prefix/share/fix.  TODO:
 bootstrap   Nix and install Nix as a Fix package.
