Eelco Dolstra a4604f1928 Add Store::buildPathsWithResults()
This function is like buildPaths(), except that it returns a vector of
BuildResults containing the exact statuses and output paths of each
derivation / substitution. This is convenient for functions like
Installable::build(), because they then don't need to do another
series of calls to get the outputs of CA derivations. It's also a
precondition to impure derivations, where we *can't* query the output
of those derivations since they're not stored in the Nix database.

Note that PathSubstitutionGoal can now also return a BuildStatus.

regnat dcf4f77fac Merge or-suggestions.hh into suggestions.hh
No real need for keeping a separate header for such a simple class.

This requires changing a bit `OrSuggestions<T>::operator*` to not throw
an `Error` to prevent a cyclic dependency. But since this error is only
thrown on programmer error, we can replace the whole method by a direct
call to `std::get` which will raise its own assertion if needs be.

Robert Hensing da260f579d dupStringWithLen -> makeImmutableString
Refactor the `size == 0` logic into a new helper function that
replaces dupStringWithLen.
The name had to change, because unlike a `dup`-function, it does
not always allocate a new string.

John Ericson 6636202356 Factor out a GcStore interface
Starts progress on #5729.

The idea is that we should not have these default methods throwing
"unimplemented". This is a small step in that direction.

I kept `addTempRoot` because it is a no-op, rather than failure. Also,
as a practical matter, it is called all over the place, while doing
other tasks, so the downcasting would be annoying.

Maybe in the future I could move the "real" `addTempRoot` to `GcStore`,
and the existing usecases use a `tryAddTempRoot` wrapper to downcast or
do nothing, but I wasn't sure whether that was a good idea so with a
bias to less churn I didn't do it yet.

This is useful whenever we want to evaluate something to a store path

Extracted from the lazy-trees branch (where we can require that a
store path must come from a store source tree accessor).

John Ericson ea71da395f Move some stuff from Settings to a new FetchSettings.
Starting work on #5638

The exact boundary between `FetchSettings` and `EvalSettings` is not
clear to me, but that's fine. First lets clean out `libstore`, and then
worry about what, if anything, should be the separation between those
two.

libstore/derivation-goal: avoid double-parsing of JSON messages
To avoid that JSON messages are parsed twice in case of
remote builds with `ssh-ng://`, I split up the original
`handleJSONLogMessage` into three parts:

* `parseJSONMessage(const std::string&)` checks if it's a message in the
  form of `@nix {...}` and tries to parse it (and prints an error if the
  parsing fails).
* `handleJSONLogMessage(nlohmann::json&, ...)` reads the fields from the
  message and passes them to the logger.
* `handleJSONLogMessage(const std::string&, ...)` behaves as before, but
  uses the two functions mentioned above as implementation.

In case of `ssh-ng://`-logs the first two methods are invoked manually.

ssh-ng: also store build logs to make them accessible by nix log
Right now when building a derivation remotely via

    $ nix build -j0 -f . hello -L --builders 'ssh://builder'

it's possible later to read through the entire build-log by running
`nix log -f . hello`. This isn't possible however when using `ssh-ng`
rather than `ssh`.

The reason for that is that there are two different ways to transfer
logs in Nix through e.g. an SSH tunnel (that are used by `ssh`/`ssh-ng`
respectively):

* `ssh://` receives its logs from the fd pointing to `builderOut`. This
  is directly passed to the "log-sink" (and to the logger on each `\n`),
  hence `nix log` works here.
* `ssh-ng://` however expects JSON-like messages (i.e. `@nix {log data
  in here}`) and passes it directly to the logger without doing anything
  with the `logSink`. However it's certainly possible to extract
  log-lines from this format as these have their own message-type in the
  JSON payload (i.e. `resBuildLogLine`).

  This is basically what I changed in this patch: if the code-path for
  `builderOut` is not reached and a `logSink` is initialized, the
  message was successfully processed by the JSON logger (i.e. it's in
  the expected format) and the line is of the expected type (i.e.
  `resBuildLogLine`), the line will be written to the log-sink as well.

Closes #5079
