Moved probe signal handling from drivers to the core, improved handling of probe disconnected signal.
NOTE: The changes above are quite large, please verify probe operation after installation.
Moved inbuilt G65 macros to the core and added macro G65P5Q<n> for selecting probe.
Added probe id to real time report: |P:<n> will be reported on probe select when more than one probe is available.
Fix for WCO and Ov real time status report elements not beeing reported as they should in some circumstances.
Added named parameters _probe_state and _toolsetter_state. Both return -1 if state is not available.
These may return incorrect values initially so use with care.
The change is major and potentially dangerous, it may damage your probe, so please verify correct operation after installing.
Fix for STM32F4xx issue 161, Ethernet connection unresponsive if USB port not powered.
Enhanced ioPorts interface: New debounce option for input pins that are interrupt capable, currently only possible to enable via plugin code - later to be made available via a $-setting.
Added some wrapper functions for simpler plugin code++
Added simple task scheduler to the core, allows interrupt routines to dispatch jobs to the foreground process, delayed tasks and repeating tasks attached to the 1 ms system timer.
Some drivers and plugins now uses the scheduler for input pin debouncing, regular polling etc. The core uses it for stepper disabling and sleep monitoring.
