Cleanflight port to Linux (LinuxFlight) status

Created a new CLI (command Line Interface) module based on C++ and uses msgProtocol for subscribing/publishing messages.  This allows components (bash shell) or transports (UDP/TCP (Configurator)) to use the CLI at the same time.  So, now one instance of CLI can process messages from anywhere. For example: Linux has bash shell so, it would be nice not to startup Configurator to get basic info.  Use the bash shell

Here it is:
LinuxFlight>help
status - show status
help
tasks - show task stats
version - show v

Next is to get the battery voltage reporting and figure out the issue with the loading.

Might have to try the RT kernel but, first load LinuxFlight on to its own processor.  Also, might have to remove CPUFREQ it is known to impact realtime performance.
