cmvlc interface to MVLC

Håkan T Johansson requested to merge cmvlc into main

At least it compiles. And is able to do a read:

Though, sometimes it gives abunch of errors when doing the VME speed tests (are those needed/wanted with bin/rwdump? Should it print the results of them then?)

Such things typically happen when something else also is accessing the VME. This is a bug in MVLC (kind of), but cmvlc currently works around that by trying again. Ahh, might be my --mux-src-scalers that run in the background.

And when anyhow at it, I'd like to suggest --bridge instead of --mvlc and --caen in rwdump?
