Add some noexcepts
This is to assert that callback functions should never throw (since
the context in which they're called may not be able to handle the
exception).

Ensure that Callback is called only once
Also, make Callback movable but uncopyable.

Matthew Bauer 87c604c1f0 Fix launchd program args
launchd has some weird syntx. Apparently the program needs to be in
the ProgramArguments, as Program appears to be ignored.

Matthew Bauer 693e68e09c Set maximum name length in Nix
Previously we allowed any length of name for Nix derivations. This is
bad because different file systems have different max lengths. To make
things predictable, I have picked a max. This was done by trying to
build this derivation:

  derivation {
    name = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
    builder = "/no-such-path";
    system = "x86_64-linux";
  }

Take off one a and it will not lead to file name too long. That ends
up being 212 a’s. An even smaller max could be picked if we want to
support more file systems.

Working backwards, this is why:

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa-${name}.drv.chroot

> 255 - 32 - 1 - 4 - 7 = 211

Don't send certain setting overrides to the daemon
These are already handled separately. This fixes warnings like

  warning: ignoring the user-specified setting 'max-jobs', because it is a restricted setting and you are not a trusted user

when using the -j flag.

Matthew Bauer 800fba1037 Use wait4path on org.nixos.nix-daemon.plist
When using a volume, the nix-daemon path may not exist. To avoid this
issue, we must use the wait4path tool. This should solve one of the
issues in multi-user on macOS Catalina.

Matthew Bauer 0463d5e36f Allow empty /nix directory in multi-user installer
With macOS catalina, we can no longer modify the root system
volume (#2925). macOS provides a system configuration file in
synthetic.conf(5) to create empty root directories. This can be used
to mount /nix to a separate volume. As a result, this directory will
need to already exist prior to installation. Instead, check for
/nix/store and /nix/var for a live Nix installation.

nix-store: fix out of sync protocol
If a NAR is already in the store, addToStore doesn't read the source
which makes the protocol go out of sync. This happens for example when
two client try to nix-copy-closure the same derivation at the same time.

Track function start and ends for flame graphs
With this patch, and this file I called `log.py`:

    #!/usr/bin/env nix-shell
    #!nix-shell -i python3 -p python3 --pure

    import sys
    from pprint import pprint

    stack = []
    timestack = []

    for line in open(sys.argv[1]):
        components = line.strip().split(" ", 2)
        if components[0] != "function-trace":
            continue

        direction = components[1]
        components = components[2].rsplit(" ", 2)

        loc = components[0]
        _at = components[1]
        time = int(components[2])

        if direction == "entered":
            stack.append(loc)
            timestack.append(time)
        elif direction == "exited":
            dur = time - timestack.pop()
            vst = ";".join(stack)
            print(f"{vst} {dur}")
            stack.pop()

and:

    nix-instantiate --trace-function-calls -vvvv ../nixpkgs/pkgs/top-level/release.nix -A unstable > log.matthewbauer 2>&1
    ./log.py ./log.matthewbauer > log.matthewbauer.folded
    flamegraph.pl --title matthewbauer-post-pr log.matthewbauer.folded > log.matthewbauer.folded.svg

Includes test cases around function call failures and tryEval. Uses
RAII so the finish is always called at the end of the function.

conf: stalled-download-timeout: make tunable
Make curl's low speed limit configurable via stalled-download-timeout.
Before, this limit was five minutes without receiving a single byte.
This is much too long as if the remote end may not have even
acknowledged the HTTP request.
