Michael Brown 1c34ca70d1 [ping] Allow termination after a specified number of packets 
Add the "-c <count>" option to the "ping" command, allowing for
automatic termination after a specified number of packets.

When a number of packets is specified:

  - if a serious error (i.e. length mismatch or content mismatch)
    occurs, then the ping will be immediately terminated with the relevant
    status code;

  - if at least one response is received successfully, and all errors
    are non-serious (i.e. timeouts or out-of-sequence responses), then
    the ping will be terminated after the final response (or timeout)
    with a success status;

  - if no responses are received successfully, then the ping will be
    terminated after the final timeout with ETIMEDOUT.

If no number of packets is specified, then the ping will continue
until manually interrupted.

Michael Brown 5e1fa5cd40 [parseopt] Add parse_timeout() 
Parsing a timeout value (specified in milliseconds) into an internal
timeout value measured in timer ticks is a common operation.  Provide
a parse_timeout() value to carry out this conversion automatically.
