Miroslav Lichvar 74f581e7ab client: randomize sequence number in requests ...

Don't rely on random source port of a connected socket alone as a
protection against spoofed packets in chronyc. Generate a fully random
32-bit sequence number for each request and modify the code to not send
a new request until the timeout expires or a valid response is received.
For a monitoring protocol this should be more than good enough.
