Min/max value computation; Tuning lock handling

BZ: 7466

- Min/max values are now correctly computed. They concern integer and fixed point parameters
- tuning mode lock issue solved: created an AutoLock class for safe lock handling
- added configuration files for a demo on Ubuntu environment
- had AMIXER subsystem plugin compliant for derivation
- LPE library: add carriage return on logs
- removed obsolete files
- some cosmetics
