PR Description
On MacOS there were some issues with the network iio_context scanning process. Inside libiio, some mutex locks are done during scanning. This blocks the UI thread and makes the app unusable. Moving into its own thread and creating a protected section (similar to calibration processes) should resolve this issue.
Besides these changes, iio-osc also needs some different fixes to get it working on MacOS (here are 2 dev branches on this matter by Cristina and Travis).
