libexpr/primops: Move attr name extraction into its own function
This now takes care of providing positioning for both the faulting value
and the faulting function call in case of an error.

libexpr: misc improvements for proper error position
When working on some more complex Nix code, there are sometimes rather
unhelpful or misleading error messages, especially if coerce-errors are
thrown.

This patch is a first steps towards improving that. I'm happy to file
more changes after that, but I'd like to gather some feedback first.

To summarize, this patch does the following things:

* Attrsets (a.k.a. `Bindings` in `libexpr`) now have a `Pos`. This is
  helpful e.g. to identify which attribute-set in `listToAttrs` is
  invalid.

* The `Value`-struct has a new method named `determinePos` which tries
  to guess the position of a value and falls back to a default if that's
  not possible.

  This can be used to provide better messages if a coercion fails.

* The new `determinePos`-API is used by `builtins.concatMap` now. With
  that change, Nix shows the exact position in the error where a wrong
  value was returned by the lambda.

  To make sure it's still obvious that `concatMap` is the problem,
  another stack-frame was added.

* The changes described above can be added to every other `primop`, but
  first I'd like to get some feedback about the overall approach.

primops/derivation: use position of currently evaluated attribute
* The position of the `name`-attribute appears in the trace.
* If e.g. `meta` has no `outPath`-attribute, a `cannot coerce set to
  string` error will be thrown where `pos` points to `name =` which is
  highly misleading.

Eelco Dolstra 8a29052cb2 PathSubstitutionGoal: Clean up pipe
If there were many top-level goals (which are not destroyed until the
very end), commands like

  $ nix copy --to 'ssh://localhost?remote-store=/tmp/nix' \
    /run/current-system --no-check-sigs --substitute-on-destination

could fail with "Too many open files". So now we do some explicit
cleanup from amDone(). It would be cleaner to separate goals from
their temporary internal state, but that would be a bigger refactor.

John Ericson 255d145ba7 Use BuildableReq for buildPaths and ensurePath
This avoids an ambiguity where the `StorePathWithOutputs { drvPath, {}
}` could mean "build `brvPath`" or "substitute `drvPath`" depending on
context.

It also brings the internals closer in line to the new CLI, by
generalizing the `Buildable` type is used there and makes that
distinction already.

In doing so, relegate `StorePathWithOutputs` to being a type just for
backwards compatibility (CLI and RPC).

John Ericson 32f4454b9f Move StorePathWithOutput utilities out of store class
These are by no means part of the notion of a store, but rather are
things that happen to use stores. (Or put another way, there's no way
we'd make them virtual methods any time soon.) It's better to move them
out of that too-big class then.

Also, this helps us remove StorePathWithOutputs from the Store interface
altogether next commit.

Bjørn Forsman edd606ae62 fetchGit: don't prefix "refs/heads/" on ref = "HEAD"
This fixes builtins.fetchGit { url = ...; ref = "HEAD"; }, that works in
stable nix (v2.3.10), but is broken in nix master:

  $ ./result/bin/nix repl
  Welcome to Nix version 2.4pre19700101_dd77f71. Type :? for help.

  nix-repl> builtins.fetchGit { url = "https://github.com/NixOS/nix"; ref = "HEAD"; }
  fetching Git repository 'https://github.com/NixOS/nix'fatal: couldn't find remote ref refs/heads/HEAD
  error: program 'git' failed with exit code 128

The documentation for builtins.fetchGit says ref = "HEAD" is the
default, so it should also be supported to explicitly pass it.

I came across this issue because poetry2nix can use ref = "HEAD" in some
situations.

Fixes #4674.

John Ericson 9d309de0de Clean up serialization for BuildResult
A few versioning mistakes were corrected:

- In 27b5747ca7, Daemon protocol had some
  version `>= 0xc` that should have been `>= 0x1c`, or `28` since the
  other conditions used decimal.

- In a2b69660a9, legacy SSH gated new CAS
  info on version 6, but version 5 in the server. It is now 6
  everywhere.

Additionally, legacy ssh was sending over more metadata than the daemon
one was. The daemon now sends that data too.

Samuel Dionne-Riel 1765711b68 tests/config: Fix config test configuration
First, "XDG_CONFIG_HOME" shouldn't be named "home", as it may be
confusing compared with `$HOME`, which an upcoming test will be using.

Then, using a fixed location for the test is problematic. Use
`$TEST_ROOT` instead.

Fix Nix to properly work with stores using a scoped IPv6 address
According to RFC4007[1], IPv6 addresses can have a so-called zone_id
separated from the actual address with `%` as delimiter. In contrast to
Nix 2.3, the version on `master` doesn't recognize it as such:

    $ nix ping-store --store ssh://root@fe80::1%18 --experimental-features nix-command
    warning: 'ping-store' is a deprecated alias for 'store ping'
    error: --- Error ----------------------------------------------------------------- nix
    don't know how to open Nix store 'ssh://root@fe80::1%18'

I modified the IPv6 match-regex accordingly to optionally detect this
part of the address. As we don't seem to do anything special with it, I
decided to leave it as part of the URL for now.

Fixes #4490
