jade d1fa446454 [emergency revert]: make pname nix once more
Embarrassingly, I submitted a CL overriding submit requirements since
I thought it was spurious failures. However, the CI failure was in fact
real, and I have hopefully learned my lesson. The CI failure is that:

```
vm-test-run-nix-upgrade-nix> machine # installing 'nix-2.18.1'
vm-test-run-nix-upgrade-nix> machine # building '/nix/store/2b6fdf7wvahd00bg2ff0393bhd597a0h-user-environment.drv'...

```

This is definitely caused by the pname not being the same, so we had
better revert that part of the change until we know we won't regress
anything by doing this.

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
```

repl: do not crash when tab-completing import errors
File not found while importing causes a SysError, not an EvalError,
which is not currently caught by the tab-completion handler. Ignoring
all SysErrors might seem "dangerous" but this is the tab-completion
handler, any exception being bubbled up from there causes unexpected
behavior (causes the whole repl to exit).

Fixes #340.

jade d05e0b9f1f fix: enlarge envSize by several times to not be close to nixpkgs size
nixpkgs has 23000 attributes, and our previous limit would be hit if you
have more than one nixpkgs in the environment, for example, because
`repl-overlays` will load the new stuff from the environment on top of
the existing environment.

This is not really testable since if we did write such a test, it would
just be testing this constant tbh...

Qyriad 6881476232 libfetchers: fallback to memory SQLite if fs IO fails
nix::fetchers::CacheImpl uses $XDG_CACHE_HOME, or its default based on
$HOME, to store its SQLite database. If the current process can't write
to that directory for whatever reason, though, any eval-time fetching
would fail just initializing the cache.

With this change, IO errors initializing the fetcher cache are logged
but ignored, and nix::fetchers::CacheImpl falls back to an in-memory¹
database instead.

Notably, this will fix any uses eval fetching while Lix itself is being
run in a derivation builder (such as during tests), as the derivation
builder does not set $XDG_CACHE_HOME, and sets $HOME to the non-existent
directory /homeless-shelter.

Before:

$ env -u XDG_CACHE_HOME HOME=/homeless-shelter nix -Lv eval --impure -E 'fetchTarball "https://git.lix.systems/lix-project/lix/archive/main.tar.gz"'
error:
       … while calling the 'fetchTarball' builtin

       error: creating directory '/homeless-shelter': Permission denied

After:

libutil: Create chmodPath function
Move the identical static `chmod_` functions in libstore to

as otherwise it will shadow the standard library chmod in the nix

for BaseError and silences this warning.

eldritch horrors 774c56094f libstore: fix old RemoteStore::addToStore serializer
having the serializer write into `*conn` is not legal because we are
in a sinkToSource that will be drained by the remote we're connected
to. writing into `*conn` directly can break the framing protocol. it
is unlikely this code was ever run: to protocol it caters to is from
2016(!) and thoroughly untested in-tree, and since it's been present
since nix 2.17 and the 1.18 protocol broken here is nix 2.0 we might
safely assume that daemons older than nix 2.1 are no longer used now

see also #325 (though that wants <2.3 gone, this is sadly only <2.1)

These commands outputs data that may not end with a newline. This

a single line of text with no output, it shows up entirely blank,
making it look like nothing happened.
