Disabling build sandboxing is a significant change to build isolation. If this
is done automatically due to namespacing issues (and sandbox-fallback not being
disabled), show the user a loud warning without the need to opt into a lot of
other log spam.

If the NIX_PATH shadows internal files, this will often break things,
hence we forbid it.

Some of the tests depended on the evaluation order chosen internally by
nix-eval-jobs, which will break when that order changes. In practice the order
is not guaranteed, and already not deterministic with multiple workers.

GCC still ICEs on coroutines, while Clang works properly. Use the latter, just
like for Lix itself.

Previously the collector-side implementation of the worker interaction protocol
was a bunch of spaghetti code. Split it apart at places where it makes sense to
be easier to follow.

As the worker processes are now properly spawned using fork-exec, they no
longer inherit the stack size from the non-main coordinator thread, but get a
main thread with reasonable stack size on their own. For this reason the
coordinator threads can use the default stack size, and turn std::thread can be
used as the only reason for the custom wrapper was to enlarge the stack.

Similar to how 7b37d5ea6a switched the subdaemons
from fork-only to fork-exec, do the same for the nix-eval-jobs workers. This is
the promised change that causes the signal handler thread to appear.

The retry added in 4c5efd4548 has never worked
properly, as releasing the pid the first time causes it to be -1 and thus
waiting for a random child on retry. While there is a good chance that this
really catches the crashed worker, this is by no means guaranteed, and it could
just as well have caught different restarting worker. Wait synchronously
instead. The worst possible outcome is a hang instead of an error message if
the worker manages to close its pipe but then fail to exit, which is not
supposed to happen in the first place.

but currently serve to enable universal support of 0.4.x and 0.5.x

Lix blocks SIGPIPE, and std::cout ignores EPIPE (actually it probably stashes
an error code in some flag that no one ever reads, with the same end result).
Consequently, nix-eval-jobs would waste resources by continuing to evaluate
even when the reader interested in the results has long gone away. Instead, use
writeToStdout, which throws an error on EPIPE, leading to the process
terminating as desired.

Right now, the worker will not receive interrupts, as it has no signal handler
thread due to the way it forks, but this will change soon. Prepare to handle
worker interruption properly, by letting the worker exit successfully in this
case and adjusting the coordinator to handle this exit gracefully.

`e`, `ae`, `j`, `jAttrs` … holy fuck this function was so much worse
than it needed to be. This refactoring includes:
- Descriptive variable names where possible
- More code comments indicating what even is happening
- Shuffled the control flow around to be more linear (move early return
conditions up, etc.) and have less rightwards-drift, to increase
readability
- Extracted `mergeAttrs` function for future changes and readability

printed one is kept, due to better typography.

Added builtins.warn` which takes two arguments: a message that is
displayed as a warning during evaluation which must be a string and a
value that is returned from the expression.
The next commits add new settings to control the behavior of the new
builtin: `debugger-on-warn` allows the user to start the debugger and
`abort-on-warn` aborts evaluation with an error.
Unlike upstream, I chose not to mark evaluation warnings from
`builtins.warn` as distinct from other warnings because that breaks the
commonly expected logging format `level: message`.

There are currently 4 different ways to run garbage collection using
lix:
- `nix-collect-garbage`
- `nix-store --gc`
- `nix store gc`
- (using the daemon directly)
As they were written all at different times, their output varies (and is
broken in some case). This unifies the display of informations in the
following ways:
- The list of paths in the results is always printed (in the nix3 cli it
is hidden unless `-v` is passed)
- The number of paths in the result set is always displayed
- The size of deleted paths is only shown when actually deleting things
(as it would have been 0B in any case)
