utils/regtools: make qeditor able to poke directly at a hwstub device

This commit add the very handy feature of being able to read registers
directly from a device using hwstub. This is mostly trivial using the hwstub
library and the biggest change here is actually:
- being able to read registers by name and/or addresses
- being able to enumerate devives
The UI code currently doesn't handle hotplug but the backend does so it should
be trivial to add in the future. It also opens up the possibility the write
registers from hwstub or save the register values to a file.
Since it relies on both hwstub and libusb, a switch has been introduced in
qmake to disable it (use -config nohwstub).
