jade 19ae87e5ce tree-wide: add support for asan!
What if you could find memory bugs in Lix without really trying very
hard? I've had variously scuffed patches to do this, but this is
blocked on boost coroutines removal at this point tbh.

Qyriad 59bf6825ef add an impl of Expr::show for ExprInheritFrom that doesn't crash
ExprVar::show() assumes it has a name. dynamic inherits do not
necessarily (ever?) have a name.

eldritch horrors 73ddc4540f libutil: generator type with on-yield value mapping
this will be the basis of non-boost coroutines in lix. anything that is
a boost coroutine *should* be representable with a Generator coroutine,
and many things that are not currently boost coroutines but behave much
like one (such as, notably, serializers) should be as well. this allows
us to greatly simplify many things that look like iteration but aren't.

Qyriad fd250c51ed add a basic libmain test for the progress bar rendering
Hooray for leaky abstraction allowing us to test this particular part of
the render pipeline.

alois31 3c0434999e tests/libcmd: set HOME to a temporary directory
The libcmd unit test creates files (more specifically, the fetcher cache) in
its home directory. In the single-user sandbox, this leads to the creation of
/homeless-shelter, since this is the default HOME and the root is writable.
Unfortunately, this conflicts with the assumption of the functional tests that
this directory does not exist. Use a different home directory to prevent these
test failures, and thus restore the ability to build inside the single-user
sandbox.

Qyriad 06e65e537b build: expose option to enable or disable precompiled std headers
They are enabled by default, and Meson will also prints whether or not
they're enabled at the bottom at the end of configuration.

Qyriad e54d4c9381 build: fix static linking with a hack
This causes libstore, libexpr, libfetchers, and libutil to be linked
with -Wl,--whole-archive to executables, when building statically.

libstore for the store backends, libexpr for the primops, libfetchers
for the fetcher backends I assume(?), and libutil for the nix::logger
initializer (which notably shows in pre-main constructors when HOME is
not owned by the user. cursed.).

This workaround should be removed when #359 is fixed.

Fixes #306.

jade 0f99ed43f1 build-time: remove 20% more by PCH'ing C++ stdlib
It seems like someone implemented precompiled headers a long time ago
and then it never got ported to meson or maybe didn't work at all.

This is, however, blessedly easy to simply implement. I went looking for
`#define` that could affect the result of precompiling the headers, and
as far as I can tell we aren't doing any of that, so this should truly
just be free build time savings.

Previous state:
Compilation (551 times):
  Parsing (frontend):         1302.1 s
  Codegen & opts (backend):    956.3 s

New state:
**** Time summary:
Compilation (567 times):
  Parsing (frontend):         1123.0 s
  Codegen & opts (backend):   1078.1 s

I wonder if the "regression" in codegen time is just doing the PCH
operation a few times, because meson does it per-target.

jade c97e17144e packaging: rename nixexpr -> lixexpr and so on
This breaks downstreams linking to us on purpose to make sure that if
someone is linking to Lix they're doing it on purpose and crucially not
mixing up Nix and Lix versions in compatibility code.

We still need to fix the internal includes to follow the same schema so
we can drop the single-level include system entirely. However, this
requires a little more effort.

This adds pkg-config for libfetchers and config.h.

Migration path:
expr.hh      -> lix/libexpr/expr.hh
nix/config.h -> lix/config.h

To apply this migration automatically, remove all `<nix/>` from
includes, so: `#include <nix/expr.hh>` -> `#include <expr.hh>`. Then,
the correct paths will be resolved from the tangled mess, and the
clang-tidy automated fix will work.

Then run the following for out of tree projects:

```
lix_root=$HOME/lix
(cd $lix_root/clang-tidy && nix develop -c 'meson setup build && ninja -C build')
run-clang-tidy -checks='-*,lix-fixincludes' -load=$lix_root/clang-tidy/build/liblix-clang-tidy.so -p build/ -fix src
```

eldritch horrors 6b08138929 filetransfer: abort transfer on receiver exception
not doing this will cause transfers that had their readers disappear to
linger. with lingering transfers the curl thread can't shut down, which
will cause nix itself to not shut down until the transfer finishes some
other way (most likely network timeouts). also add a new test for this.

Winter Cute 6646b80396 meson: add missing explicit dependency on nlohmann_json
Without this, the Meson setup won't bail out if nlohmann_json is
missing, leading to subpar DX (and maybe worse, but I'm not entirely
sure).

Qyriad e1ffe56793 meson: implement unit tests
Unit tests can be run with `meson test -C build --suite check`.
`--suite check` is optional, as right now that's the only test suite,
but when functional tests are added those will be in a separate suite.
