Eelco Dolstra 47f7e5585b Make 'nix copy --from ssh://...' run in constant memory
For instance, this reduced the memory consumption of

  $ nix copy --from ssh://localhost --to ~/my-nix /nix/store/1n7x0yv8vq6zi90hfmian84vdhd04bgp-blender-2.79a

from 632 MiB to 16 MiB.

ssh-ng: Don't forward options to the daemon.
This can be iterated on and currently leaves out settings we know we
want to forward, but it fixes #1713 and fixes #1935 and isn't
fundamentally broken like the status quo. Future changes are suggested
in a comment.

Add a Config class to simplify adding configuration settings
The typical use is to inherit Config and add Setting<T> members:

  class MyClass : private Config
  {
    Setting<int> foo{this, 123, "foo", "the number of foos to use"};
    Setting<std::string> bar{this, "blabla", "bar", "the name of the bar"};

    MyClass() : Config(readConfigFile("/etc/my-app.conf"))
    {
      std::cout << foo << "\n"; // will print 123 unless overriden
    }
  };

Currently, this is used by Store and its subclasses for store
parameters. You now get a warning if you specify a non-existant store
parameter in a store URI.

ssh:// -> ssh-ng://, legacy-ssh:// -> ssh:// 2017-03-16 14:19:32 +01:00

Improve SSH handling
* Unify SSH code in SSHStore and LegacySSHStore.

* Fix a race starting the SSH master. We now wait synchronously for
  the SSH master to finish starting. This prevents the SSH clients
  from starting their own connections.

* Don't use a master if max-connections == 1.

* Add a "max-connections" store parameter.

* Add a "compress" store parameter.
