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.

Update libvaxis. The latest commit of libvaxis includes `uucode` as the
unicode
library. `uucode` has a much cleaner API and is actively developed by a
Ghostty
maintainer (@jacobsandlund). This also has the advantage of removing the
last
transitive dependency Ghostty has that is hosted on codeberg, which
separates us
from the frequent outages.
Disclosures: I used AI to debug the import issue in `boo.zig`

Add a `+boo` command to show the animation from the website. The data
for the frames is compressed during the build process. This build step
was added to the SharedDeps object because it is used in both
libghostty and in binaries.
The compression is done as follows:
- All files are concatenated together using \x01 as a combining byte
- The files are compressed to a cached build file
- A zig file is written to stdout which `@embedFile`s the compressed
file and exposes it to the importer
- A new anonymous module "framedata" is added in the SharedDeps object
Any file can import framedata and access the compressed bytes via
`framedata.compressed`. In the `boo` command, we decompress the file and
split it into frames for use in the animation.
The overall addition to the binary size is 348k.
