Fix for vppctl and interactive commands (VPP-1038)
- Interactive commands like "ping" read extra input from the
input stream.
- In the case of "ping" it is simply a signal to cease the current
operation.
- "vppctl", in non-interactive mode, will issue a "quit" immediately
after the requested command to queue up closing of the session.
- This resulted in "ping" thinking a keypress was seen and returning
control to the CLI; the "quit" command however is consumed by the
keypress event handler and thus the session does not close.
- This patch reworks vppctl slightly to only issue "quit" after the
command has completed. In particular it uses the fact that VPP issues
NUL bytes as a surrogate prompt between output of commands to signal
acknowledgement that the command has completed; vppctl now flags
that the quit should be issued after the next such acknowledgement.
- Since input it still accepted, the user can still terminate the
"ping" early, if desired.
