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.

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.

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.

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.

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.

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.

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.

We're going for Dragon's Breath because horrors called dibs on it.
It's fine to merge this a little before the final release, since all the
dev versions have -pre in them anyway.

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

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

this is a bit of a hack, but it's apparently the cleanest way of doing
this in the absence of any kind of priority/provenance information for
values of some given setting. we'll need this to deprecate build-hook.

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.

* changes:
sqlite: add a Use::fromStrNullable
util: implement charptr_cast
tree-wide: fix a pile of lints
refactor: make HashType and Base enum classes for type safety
build: integrate clang-tidy into CI
This lets us ensure that nobody is putting in new reinterpret_cast
instances where they could safely use charptr_cast instead.
Change-Id: I6358a3934c8133c7150042635843bdbb6b9218d4
There were several usages of the raw sqlite primitives along with C
style casts, seemingly because nobody thought to use an optional for
getting a string or NULL.
Let's fix this API given we already *have* a wrapper.

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.

This:
- Converts a bunch of C style casts into C++ casts.
- Removes some very silly pointer subtraction code (which is no more or
less busted on i686 than it began)
- Fixes some "technically UB" that never had to be UB in the first
place.
- Makes finally follow the noexcept status of the inner function. Maybe
in the future we should ban the function from not being noexcept, but
that is not today.
- Makes various locally-used exceptions inherit from std::exception.

This still has utterly unacceptably bad output format design that I
would not inflict on anyone I like, but it *does* now exist, and you
*can* find the errors in the log.
Future work would obviously be to fix that and integrate the actual
errors into Gerrit using codechecker or so.

This is not a proper fix for the confusion that can happen about how the
tags are supposed to be used.
For a proper fix, we need to do
lix-project/lix#439 and implement
worktrees such that the user never sees the git state anymore.

This was broken because Nix language's version comparison does not know
how to deal with versions like -rc1 and considers them newer, which is
in this case not desirable.
That in turn led to not tagging 2.90.0 docker images as "latest" since
the heuristic was wrong.
This commit also adds some more cross-checking and failsafes in case the
person running releng does not have a local main branch that is up to
date.

Currently, the parser relies on the global experimental feature flags.
In order to properly test conditional language features, we instead need
to pass it around in the parser::State.
This means that the parser cannot cache the result of isEnabled anymore,
which wouldn't necessarily hurt performance if the function didn't
perform a linear search on the list of enabled features on every single
call. While we could simply evaluate once at the start of parsing and
cache the result in the parser state, the more sustainable solution
would be to fix `isEnabled` such that all callers may profit from the
performance improvement.

This adds a second form to the `:log` command: it now can accept a
derivation path in addition to a derivation expression. As derivation
store paths start with `/nix/store`, this is not ambiguous.
