Eelco Dolstra 0687e16c4a Fix a crash in DerivedPath::Built::toJSON() with impure derivations
The use of 'nullptr' here didn't result in a null JSON value, but in a
nullptr being cast to a string, which aborts.

Naïm Favier 1f3c0a3c1d Allow disabling build users by unsetting build-users-group
Unsetting `build-users-group` (without `auto-allocate-uids` enabled)
gives the following error:

```
src/libstore/lock.cc:25: static std::unique_ptr<nix::UserLock> nix::SimpleUserLock::acquire(): Assertion `settings.buildUsersGroup != ""' failed.
```

Fix the logic in `useBuildUsers` and document the default value
for `build-users-group`.

Eelco Dolstra ae5f62a894 Move isUri() and resolveUri() out of filetransfer.cc
These are purely related to NIX_PATH / -I command line parsing, so put
them in libexpr.

Linus Heckemann 8e0946e8df Remove repeat and enforce-determinism options
These only functioned if a very narrow combination of conditions held:

- The result path does not yet exist (--check did not result in
  repeated builds), AND
- The result path is not available from any configured substituters, AND
- No remote builders that can build the path are available.

If any of these do not hold, a derivation would be built 0 or 1 times
regardless of the repeat option. Thus, remove it to avoid confusion.

Eelco Dolstra 5b798f6cae Fix random client failures during GC server shutdown
We need to close the GC server socket before shutting down the active
GC client connections, otherwise a client may (re)connect and get
ECONNRESET. But also handle ECONNRESET for resilience.

Fixes random failures like

  GC socket disconnected
  connecting to '/tmp/nix-shell.y07M0H/nix-test/default/var/nix/gc-socket/socket'
  sending GC root '/tmp/nix-shell.y07M0H/nix-test/default/store/kb5yzija0f1x5xkqkgclrdzldxj6nnc6-non-blocking'
  reading GC root from client: error: unexpected EOF reading a line
  1 store paths deleted, 0.00 MiB freed
  error: reading from file: Connection reset by peer

in gc-non-blocking.sh.

Eelco Dolstra 3d23b9d032 SimpleUserLock::getSupplementaryGIDs(): Filter out main gid

well.

Eelco Dolstra b37c2d84b6 Always call setgroups()
We shouldn't skip this if the supplementary group list is empty,
because then the sandbox won't drop the supplementary groups of the
parent (like "root").

resource limits and getting some build stats.

Robert Hensing 7e162c69fe derivation-goal: Fix requires non-existing output error
It occurred when a output of the dependency was already available,
so it didn't need rebuilding and didn't get added to the
inputDrvOutputs.
This process-related info wasn't suitable for the purpose of finding
the actual input paths for the builder. It is better to do this in
absolute terms by querying the store.
