This is enough to get less complex cuda applications running, and is a
good starting spot to slowly finish off the remaining implementation.
Some information:
- 429 functions in total
- 153 only compiled for 64-bit (35.6%)
- 7 functions disabled entirely (1.6%)
The main thing /not/ working with this initial implementation is .cu
files compiled in to an ELF using the static cuda runtime. This is due
to the `cuGetExportTable` function being stubbed out and the static cuda
RT requires at least two interfaces from that function before it
continues.
This function isn't publicly documented by NVIDIA but has been publicly
reverse engineered to be fairly trivial. It's just a jump table with the
first element being the size of the table in bytes.
That will be the next step of the implementation.
I was hitting an issue where thunking in Wine+Vulkan applications was breaking
unless both OpenGL and Vulkan was enabled.
Turns out this was because Vulkan enabled only XCB, which didn't enable
X11. So when XCB is thunked but X11 isn't, this causes weird issues
where X11 calls in to XCB functions and gets in desync'ed state. Causing
hangs to appear in xcb_take_socket.
Now we can enabled just `Vulkan` as a thunk and it'll work fine.
```

```
Removes the @PREFIX_ARCH@ replacement string in the thunks path.
The library prefix paths now get generated upfront and everything gets
replaced to handle the differences between multiarch distros.
Fixes Thunks on Arch and Fedora.
Since we have switched over to thunking the vulkan loader, behaviour has
changed here and we need to thunk this library.
While a bit unsafe to thunk arbitrary libraries, we know this one is
safe to thunk.
Fixes thunking Vulkan on steam games which have been broken since
switching over to vulkan loader thunking.
In the future this may become unnecessary but it is required for now.
Instead of duplicating prefixes in the ThunksDB json file even more,
just do a prefix replacement when the thunks database is being parsed.
Changes the JSON overlay arrays over to @PREFIX@ and reduce the
duplication.
Adds support for the pressure-vessel prefix `/usr/lib/pressure-vessel/overrides/lib`
This gets thunks ready for running under pressure-vessel, once vulkan
thunking switches from device libraries to the vulkan loader it should
just work.
