Move path info caching from BinaryCacheStore to Store
...
Caching path info is generally useful. For instance, it speeds up "nix
path-info -rS /run/current-system" (i.e. showing the closure sizes of
all paths in the closure of the current system) from 5.6s to 0.15s.
This also eliminates some APIs like Store::queryDeriver() and
Store::queryReferences().

BinaryCacheStore::readFile(): Return a shared_ptr to a string
...
This allows readFile() to indicate that a file doesn't exist, and
might eliminate some large string copying.

Add Store::dumpPath() method
...
This allows applying nix-store --verify-path to binary cache stores:
NIX_REMOTE=https://cache.nixos.org nix-store --verify-path /nix/store/s5c7...

BinaryCacheStore::isValidPath(): Use .narinfo cache
...
If a path is in the .narinfo cache, obviously it's valid.

BinaryCacheStore: Remove publicKeyFile argument
...
The public key can be derived from the secret key, so there's no need
for the user to supply it separately.

importPaths(): Optionally add NARs to binary cache accessor
...
This enables an optimisation in hydra-queue-runner, preventing a
download of a NAR it just uploaded to the cache when reading files
like hydra-build-products.

Add NAR / Store accessor abstraction
...
This is primary to allow hydra-queue-runner to extract files like
"nix-support/hydra-build-products" from NARs in binary caches.

So now you can do
$ NIX_REMOTE=file:///tmp/binary-cache nix-instantiate '<nixpkgs>' -A hello
and lots of other operations.
