implement timeval timeout for BroadcastReceiver::operator()
add support for timeout == NULL in BroadcastReceiver::operator()
use nanosleep to speed up unittest of BroadcastReceiver.
there are still threading issues in that test because the test can send packages to early, when the receiver thread dont get time to get into its listen state again. We cannot avoid this behavior on a non realtime os without changing the test design and wrapping the testsockets.
increased sleeptime 5ms it was 0.1ms!!!
add default timeout=NULL to operator()
fix bug in Cli: we want to scan for broadcasts until user selects a remote. (timeout=NULL)
deactivate failing unittest ScriptBuf_FullBuffer
simplified WiflyControl use always TcpSocket for communication
reduce pointer usage, we use references instead
fix bug in ComProxy_ut.cpp
harmonized timeval usage in BroadcastReceiver and ComProxy
