Fix GDBRemoteCommunicationClientTest.TestPacketSpeedJSON

The mock server was listening for only one packet (I forgot to put a loop around

the tested function does not check or report errors (which should be fixed).

long time now (8s), I have added a parameter to control the amount of data sent

Note that I spent some time looking at alternatives. CGP is actually

Further, all of the neighboring optimization techniques actually have
