Reimplement `gopacket.PacketSource.PacketsCtx` as `forEachPacket`. - Use `ZeroCopyPacketDataSource` instead of `PacketDataSource`. I didn't find any specific reason why `PacketDataSource` exists at all, since `NewPacket` is doing copy inside if you don't explicitly tell it not to. - Use `WillPool` to pool packet buffers. It doesn't fully remove allocations, but it's a safe start. Send packets back into the pool after we are done with them. - Pass `Packet` directly to the closure instead of waiting for it on the channel. We don't store this packet anywhere so there is no reason to async this part. - Drop `time.Sleep` code in `forEachPacket` body. - Drop `SnapLen` support in client and server since it didn't work anyway (details in the PR).
