Eelco Dolstra 69fe6c58fa Move some code around 
In particular, do replacing of valid paths during repair later.  This
prevents us from replacing a valid path after the build fails.

Eelco Dolstra 00d30496ca Heuristically detect if a build may have failed due to a full disk 
This will allow Hydra to detect that a build should not be marked as
"permanently failed", allowing it to be retried later.

Eelco Dolstra e81d38c02b nix-shell: Execute shellHook if it exists 
Since normal builds don't execute shellHook, this allows nix-shell
specific customisation.  Suggested by Domen.

Eelco Dolstra 57386c9bae Binary tarball: Automatically create /nix

Shea Levy 64e23d0a38 Add download-via-ssh substituter 
This substituter connects to a remote host, runs nix-store --serve
there, and then forwards substituter commands on to the remote host and
sends their results to the calling program. The ssh-substituter-hosts
option can be specified as a list of hosts to try.

This is an initial implementation and, while it works, it has some
limitations:

* Only the first host is used
* There is no caching of query results (all queries are sent to the
  remote machine)
* There is no informative output (such as progress bars)
* Some failure modes may cause unhelpful error messages
* There is no concept of trusted-ssh-substituter-hosts

Shea Levy 9488447594 nix-store --serve: Don't loop forever 
nix-store --export takes a tmproot, which can only release by exiting.
Substituters don't currently work in a way that could take advantage of
the looping, anyway.

Shea Levy 3a38d0f356 Add the nix-store --serve command 
This is essentially the substituter API operating on the local store,
which will be used by the ssh substituter. It runs in a loop rather than
just taking one command so that in the future nix will be able to keep
one connection open for multiple instances of the substituter.

Shea Levy 0c3e8a616e nix-instantiate: Add a --no-readonly-mode flag 
This allows running nix-instantiate --eval-only without performing the
evaluation in readonly mode, letting features like import from
derivation and automatic substitution of builtins.storePath paths work.

Eelco Dolstra d210cdc435 Fix assertion failure in ‘nix-store --load-db’ 
Namely:

  nix-store: derivations.cc:242: nix::Hash nix::hashDerivationModulo(nix::StoreAPI&, nix::Derivation): Assertion `store.isValidPath(i->first)' failed.

This happened because of the derivation output correctness check being
applied before the references of a derivation are valid.
