Removed HAL dependant code. #13

Beside the code removal, there has been some class and enum renaming.
Build fine here in bullseye, suggest we test on other distros too.

Tested building on Bullseye@i386 and Xenial@i386 – both successfully.
There is one note for consideration, see below.

Done, thanks for testing on old distros.
