[Feature] Linux io_uring support about 1 year ago

AI Summary: Implement io_uring support in the tcpreplay project, mirroring the existing libxdp implementation. This involves adding a new build option and a command-line flag to enable io_uring as an alternative network sending method, prioritizing it as the default when available. The implementation should aim for compatibility and performance similar to netmap.

Complexity: 4/5
