85c8be6286 Remove static variable name clashes
This was useful for an experiment with building Nix as a single
compilation unit. It's not very useful otherwise but also doesn't
hurt...

d51ba43047 Move Callback into its own header
This gets rid of the inclusion of <future> in util.hh, cutting
compilation time by ~20s (CPU time).

Issue #4045.

fa08db5c4c wopAddToStore: return ValidPathInfo
A ValidPathInfo is created anyway. By returning it we can save a
roundtrip and we have a nicer interface.

5895184df4 Correctly call all the parent contructors of the stores

22afa8fb4d Separate store configs from the implems
Rework the `Store` hierarchy so that there's now one hierarchy for the
store configs and one for the implementations (where each implementation
extends the corresponding config). So a class hierarchy like

```
StoreConfig-------->Store
    |                 |
    v                 v
SubStoreConfig----->SubStore
    |                 |
    v                 v
SubSubStoreConfig-->SubSubStore
```

(with virtual inheritance to prevent DDD).

The advantage of this architecture is that we can now introspect the configuration of a store without having to instantiate the store itself

7d5bdf8b56 Make the store plugins more introspectable
Directly register the store classes rather than a function to build an
instance of them.
This gives the possibility to introspect static members of the class or
choose different ways of instantiating them.

057c6203b5 gracefully handle old daemon versions
Add a fallback path in `queryPartialDerivationOutputMap` for daemons
that don't support it.

Also upstreams a couple methods from `SSHStore` to `RemoteStore` as this
is needed to handle the fallback path.

Fix unspecified behaviour in readStorePathCAMap
When deploying a Hydra instance with current Nix master, most builds
would not run because of errors like this:

  queue monitor: error: --- Error --- hydra-queue-runner
  error: --- UsageError --- nix-daemon
  not a content address because it is not in the form '<prefix>:<rest>': /nix/store/...-somedrv

The last error message is from parseContentAddress, which expects a
colon-separated string, however what we got here is a store path.

Looking at the worker protocol, the following message sent to the Nix
daemon caused the error above:

  0x1E -> wopQuerySubstitutablePathInfos
  0x01 -> Number of paths
  0x16 -> Length of string
  "/nix/store/...-somedrv"
  0x00 -> Length of string
  ""

Looking at writeStorePathCAMap, the store path is indeed the first field
that's transmitted. However, readStorePathCAMap expects it to be the
*second* field *on my machine*, since expression evaluation order is a
classic form of unspecified behaviour[1] in C++.

This has been introduced in https://github.com/NixOS/nix/pull/3689,
specifically in commit 66a62b3189.

a0f19d9f3a RemoteStore::addToStore(): Fix race between stderrThread and NAR writer
As pointed out by @B4dM4n, the call to to.flush() on stderrThread is
unsafe because the NAR writer thread is also writing to 'to'.

Fixes #3943.

47644e49ca Specialize std::optional<StorePath> so this is backwards compatible
While I am cautious to break parametricity, I think it's OK in this
cases---we're not about to try to do some crazy polymorphic protocol
anytime soon.
