Linux runtime: overrun detection for real-time timers and for plc execution.
If real-time timer wakes-up PLC thread too late (10% over period), then
warning is logged.
If PLC code (IO retreive, execution, IO publish) takes longer than requested
PLC execution cycle, then warning is logged, and CPU hoogging is mitigated
by delaying next PLC execution a few cylces more until having at least
1ms minimal idle time.

longdesc

Arguments are either:
- name=value: setting variable with literal value.
- name=other_name: copy variable content into another
"active"+"inactive" labeled elements can be provided to show feedback when pressed
Exemples:
HMI:Assign:notify=1@notify=/PLCVAR
HMI:Assign:ack=2:notify=1@ack=.local_var@notify=/PLCVAR
