6bf7dc1baf download: if there are active requests, never sleep for 10s 
In some versions/configurations libcurl doesn't handle timeouts
(especially DNS timeouts) in a way that wakes curl_multi_wait.

This doesn't appear to be a problem if using c-ares, FWIW.

use debug instead of printTalkative to avoid spamming hydra queue

54b1c59643 download.cc: fix readCallback return type (int -> size_t) 
I'm not sure if curl ever asks for enough data at once
for truncation to occur but better safe than sorry.

Make <nix/fetchurl.nix> run in constant memory 
E.g.

  nix-build --store ~/my-nix/ -E 'import <nix/fetchurl.nix> { url = https://cache.nixos.org/nar/0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv.nar.xz; sha256 = "0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv"; }'

now runs in 17 MiB (was 70 MiB), while

  nix-build --store ~/my-nix/ -E 'import <nix/fetchurl.nix> { url = https://cache.nixos.org/nar/0nwi996rgq4b914qyx0mv2wq4k80hjac7xilikavagw7kxmn2iiv.nar.xz; sha256 = "0d2fxljdih3nc5dqx41hjzic3141ajil94m8kdbpryq569dpsbvb"; unpack = true; }'

runs in 17 MiB (was 346 MiB).

Make HttpBinaryCacheStore::narFromPath() run in constant memory 
This reduces memory consumption of

  nix copy --from https://cache.nixos.org --to ~/my-nix /nix/store/95cwv4q54dc6giaqv6q6p4r02ia2km35-blender-2.79

from 176 MiB to 82 MiB. (The remaining memory is probably due to xz
decompression overhead.)

Make LocalBinaryCacheStore::narFromPath() run in constant memory 
This reduces memory consumption of

  nix copy --from file://... --to ~/my-nix /nix/store/95cwv4q54dc6giaqv6q6p4r02ia2km35-blender-2.79

from 514 MiB to 18 MiB for an uncompressed binary cache, and from 192
MiB to 53 MiB for a bzipped binary cache. It may also be faster
because fetching can happen concurrently with decompression/writing.

Continuation of 48662d151b.

Modularize config settings 
Allow global config settings to be defined in multiple Config
classes. For example, this means that libutil can have settings and
evaluator settings can be moved out of libstore. The Config classes
are registered in a new GlobalConfig class to which config files
etc. are applied.

Relevant to https://github.com/NixOS/nix/issues/2009 in that it
removes the need for ad hoc handling of useCaseHack, which was the
underlying cause of that issue.

Make 'nix copy --to daemon' run in constant memory (daemon side) 
Continuation of 97002b684c. This makes
the daemon use constant memory. For example, it reduces the daemon's
maximum RSS on

  $ nix copy --from ~/my-nix --to daemon /nix/store/1n7x0yv8vq6zi90hfmian84vdhd04bgp-blender-2.79a

from 264 MiB to 7 MiB.

We now use a TunnelSource to prevent the connection from ending up in
an undefined state if an exception is thrown while the NAR is being
sent.

Make Env self-describing 
If the Env denotes a 'with', then values[0] may be an Expr* cast to a
Value*. For code that generically traverses Values/Envs, it's useful
to know this.

In restricted eval mode, allow access to the closure of store paths 
E.g. this makes

  nix eval --restrict-eval -I /nix/store/foo '(builtins.readFile "/nix/store/foo/symlink/bla")'

(where /nix/store/foo/symlink is a symlink to another path in the
closure of /nix/store/foo) succeed.

This fixes a regression in Hydra compared to Nix 1.x (where there were
no restrictions at all on access to the Nix store).
