linux: introduce io_uring support (#3952)
Add io_uring support for several asynchronous file operations:
- read, write
- fsync, fdatasync
- stat, fstat, lstat
io_uring is used when the kernel is new enough, otherwise libuv simply
falls back to the thread pool.
Performance looks great; an 8x increase in throughput has been observed.
This work was sponsored by ISC, the Internet Systems Consortium.
Fixes: https://github.com/libuv/libuv/issues/1947
