There's other adjustment/addition: * Function name CQE/SQE renamed to Cqe/Sqe. * SQ entry union sets value withput util to reduce function complexity, so leaving function budget for another stuff. * UserData has its own type, implement for uint64, uintptr, and unsafe. * TODO: decide what to use `Syscall` or `RawSyscall`. * Exposed `SeenCqe`. * Ignore *.test file extension. * Inline cost tool.
