Qt: Add interface toolbar support

An extcap utility can provide configuration for controls to use in a
GUI interface toolbar.  This controls are bidirectional and can be
used to control the extcap utility while capturing.

This is useful in scenarios where configuration can be done based on
findings in the capture process, setting temporary values or give other
inputs without restarting current capture.

Todo:
- Add support for Windows
