   *  - Added ATTR_ALWAYS_INLINE attribute to several key inlined library components, to ensure they are inlined in all circumstances
   *  - Removed SetSystemClockPrescaler() macro, the clock_prescale_set() avr-libc macro has been corrected in recent avr-libc versions
   *  - Fixed incorrect/missing control status stage transfers on demos, bootloaders and applications (thanks to Nate Lawson)
