e513cd2beb libstore: run childStarted as late as possible
otherwise we *technically* give away the output fds before we've read them.

fb8eb539fc libstore: move respect-timeoutiness to goal method
this is useless to do on the face of it, but it'll make it easier to
convert the entire output handling to use async io and promises soon

5cbca85535 libstore: clarify that build log fd and hook log fd are different
only DerivationGoal can set the hook to anything at all. it always sets
buildOutFD to something that is not related to fromHook in any way, and
mixing the two would have rather dire consequences for log consistency.

Apparently it was impolite to lint with 128 jobs on our CI machine with
128 threads. Let's fix it.

84543b459c doc: fix broken meson deps for various manuals outputs
This is incredibly haunted, but it can happen that you change libutil,
breaking the generation of the .json files, which then does not rebuild
the files. I don't expect they are slow to build, so it does not seem so
bad to just rebuild them every time instead of extracting a list of all
the possible deps.

We want to delete this nonsense anyway and replace it with generated
code.

e2d330aeed libstore: remove DerivationGoal::isReadDesc
all derivation goals need a log fd of some description. let's save this
single fd in a dedicated pointer field for all subclasses so that later
we have just the one spot to change if we turn this into async promises

38f550708d libstore: add explicit in-build-slot-ness to goals
we don't need to expose information about how busy a Worker is if the
worker can instead tell its work items whether they are in a slot. in
the future we might use this to not start items waiting for a slot if
no slots are currently available, but that requires more preparation.

41a0b08e64 meson: Don't use target_machine
The target_machine variable is meant for the target
of cross compilers. We are not a cross compiler, so
instead reuse our host_machine based checks.

Fixes Linux→FreeBSD cross, since Meson can't figure
out `target_machine.kernel()` in that case.

5137cea990 README: clarify license to match documentation
For years both the documentation and nixpkgs have said that CppNix is
LGPL-2.1-or-later, not LGPL-2.1-only as is somewhat implied by the
README. We are choosing to update the README to match the rest of the
references.

b9ed79c99a libutil: deal with Linux systems that do not implement close_range
Seems a little bit Rich that musl does not implement close_range because
they suspect that the system call itself is a bad idea, so they uhhhh
are considering not implementing a wrapper. Let's just fix the problem
at hand by writing our own wrapper.

b15d5cc6ee nix: remove explosions if you have a window size less than four
Turns out strings do not like being resized to -4.

This was discovered while messing with the tests to remove unbuffer and
trying stdbuf instead. Turns out that was not the right approach.

This basically rewrites the handling of this case to be much more
correct, and fixes a bug where with small window sizes where it would
ALSO truncate the attr names in addition to the optional descriptions.

0c76195351 build: remove expect as a dependency
I was packaging Lix 2.91 for nixpkgs and was annoyed at the expect
dependency. Turns out that you can replace unbuffer with a pretty-short
Python script.

It became less short after I found out that Linux was converting \n to
\r\n in the terminal subsystem, which was not very funny, but is at
least solved by twiddling termios bits.

292567e0b0 fix: check if it is a Real terminal, not just if it is a terminal
This will stop printing stuff to dumb terminals that they don't support.

I've overall audited usage of isatty and replaced the ones with intent
to mean "is a Real terminal" with checking for that. I've also caught a
case of carelessly assuming "is a tty" means "should be colour" in
nix-env.

3775b6ac88 package: remove unused autotools code, empty file
I noticed there was some stuff setting configureFlags that definitely do
not do anything with meson, so let's rip them out.

As for the empty file, it was added when I was thinking I needed a fake
C++ target to convince meson to create the necessary dependencies. That
was not in fact possible so it should have never been committed.

c7d97802e4 libutil: rename and optimize closeMostFDs
this is only used to close non-stdio files in derivation sandboxes. we
may as well encode that in its name, drop the unnecessary integer set,
and use close_range to deal with the actual closing of files. not only
is this clearer, it also makes sandbox setup on linux fast by 1ms each

35a2f28a46 libstore: deprecate the build-hook setting
implementing a build hook is pretty much impossible without either being
a nix, or blindly forwarding the important bits of all build requests to
some kind of nix. we've found no uses of build-hook in the wild, and the
build-hook protocol (apart from being entirely undocumented) is not able
to convey any kind of versioning information between hook and daemon. if
we want to upgrade this infrastructure (which we do), this must not stay

baa4fda340 main: require argv[0]
sure, linux has been providing argv[0] by default for a while now. other
OSes may not be as forthcoming though, and relying on the OS to create a
world in which we can just make assumptions we could test for instead is
unnecessarily lazy. we *could* default argv0, but that's a little silly.

notably we abort instead of returning normally to avoid confusions where
a caller interprets our exit status like a Worker build results bitmask.

a318c96851 util: implement charptr_cast
I don't like having so many reinterpret_cast statements that have to
actually be looked at to determine if they are UB. A huge number of the
reinterpret_cast instances in Lix are actually casting to some pointer
of some character type, which is always valid no matter the source type.

However, it is also worth looking at if it is not casting both *from* a
character type and also *to* a character type, since IMO splatting a
struct into a character array should be a very deliberate action instead
of just being about dealing with bad APIs.

So let's write a template that encapsulates this invariant so we can
not worry about the trivially safe reinterpret_cast invocations.

  that is not today.
- Makes various locally-used exceptions inherit from std::exception.
