This commit represents the majority of the work necessary to upgrade
Ghostty to use Zig 0.16.0.
Key parts:
* In addition to its previous responsibilities, the global state now
houses state for global I/O implementations and the process
environment. It is now also utilized in the main application along
with the C library. Where necessary, global state is isolated from key
parts of the implementation (e.g., in libghostty subsystems), and it's
expected that this list will grow.
* We currently manage our own C translation layer where necessary. In
these cases, cImport has been removed in favor of the new external
translate-c package. Due to fixes that have needed be made to properly
translate the dependencies that were swapped out, as mentioned, we
have had to backport fixes from the current translate-c package (and
the upstream Arocc dependency). We will host this ourselves until Zig
0.17.0 is released with these fixes.
* Where necessary (only a small number of cases), some stdlib code from
0.15.2 (and even from 0.17.0) has been taken, adopted, and vendored in
lib/compat.

The `zon2nix` binary is now compiled with Zig 0.16, but it still produces
Zig 0.15 compatible output (in fact the output is identical to previous
versions).
As of NixOS/nixpkgs#473413[1], `zig.hook` no longer supports
`zig_default_flags`, and now they can and must be provided in
`zigBuildFlags` instead.
Updating also requires removing gnome-xorg since it has been removed
from nixpkgs.

This adds a couple of Nix-based VM integration tests:
- Does `ghostty +version` run successfully?
- Can we create a new terminal window? (This is detected by setting the
background to a color that doesn't appear
normally on the desktop and seeing if we can detect that color in a
screenshot).
Obviously more can be done but I thought that these would be a couple of
good first steps.
The whole test suite can be run with `nix flake check`. Individual tests
can be run with a command like this:
```
nix run .#check.x86_64-linux.<test name>.driver
```
- update nixpkgs now that Zig 0.15.2 is available in nixpkgs
- drop hack that worked around compile failures on systems with more
than 32 cores
- enforce patch version of Zig
- Builds with Zig 0.15 now (but still works just fine with Zig
0.14 projects).
- Fixes a double-free if nix-prefetch-git can't be found or errors out
- Adds support for generating Flatpak package metadata natively.
Update to Nix 25.05 which gets us GTK 4.18, libadwaita 1.7, and Zig 0.14.1.
Since Nix updated to Zig 0.14.1, the devshell has been switched to Zig 0.14.1
from zig-overlay as well.
Fixes#7305
Upstream is now mostly pure Zig and the build.zig.zon.* files are
generated directly by zon2nix. The JSON file is no longer used as an
intermediate file but is retained for downstream packager usage.
This brings the internal package more in line with how the nixpkgs
package is built. It also handles recursive dependencies better than the
current system.
Fixes#2171
ZLS has caused us issues in our Nix shell before and I noted when we
first added it that we probably shouldn't. We now pin to release
versions of Zig so I think its reasonable to expect developers to have
ZLS installed themselves with the proper version or not use it at all.
this should reduce the amount of rebuilds that need to occur that due to
the souce changing invalidating the cache
also note that a update to nixpkgs-stable had to occur such that the new
lib functions existed
This is the result of running `nix flake update zls`.
For some reason updating zig itself doesn't help. There are two mentions
of zig-overlay in the lock file so I imagine that has something to do
with that. As in - the version used by zls was the one with the problem.
Fixes this isssue:
