Use PosixPath

[georgefst]

I'm not quite certain whether we should be using OsPath or PosixPath. The filepath library could perhaps be clearer about the distinction. I think the latter is preferable since this is a Linux-specific library. And I kind of have to use it anyway due to unix (see openFd).

But then doesFileExist and listDirectory want OsPath, hence the conversions here via internal constructors. I think, looking at the file-io library, the intention is that utilities are duplicated for OsPath and PlatformPath, and the problem is maybe just that directory doesn't have the latter for some reason.

We also still have fsnotify, which still uses plain old strings, but will presumably eventually switch to using OsPath not PosixPath since, unlike us, it's cross-platform...

There is this blog post by Hasufell that explains the intended use for each type.

I think you got it right: evdev should use PosixString/PosixPath (since it is platform specific) and the problem lies in the libraries that evdev depends on that 1. are platform-agnostic but 2. don't provide a platform-specific interface (based on PlatformString/PlatformPath) to avoid conversions.
