io_uring.h is included in a public interface header file about libunifex

[lewissbaker]

libunifex is only really using the core syscall parts of io_uring and isn't making use of any of the liburing helpers.

However, I have had difficulty trying to just include the platform's linux/io_uring.h header and so have been using the one from liburing as it seems more portable across different sets of linux platform headers. This may just be a shortcoming of trying to use kernel versions and corresponding headers other than the one installed on the distro by default.

I'd be happy to bundle a version of the linux/io_uring.h header that contains the required structs and constants needed for the syscalls. I'll investigate a solution in this direction.

Linux tends to not break kernel ABI, so you can probably safely hard code this stuff into a local header. LLFIO does a ton of that for Windows as we make such extensive use of the NT kernel API. None of those NT kernel APIs have changed since NT 3.5, to my knowledge, though many new ones have been added since.
