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.

Mutlistateh widget hides all subelements whose label do not match given
variable value representation. For exemple if given variable type
is HMI_INT and value is 1, then elements with label '1' will be displayed.
Label can have comments, so '1#some comment' would also match. If matching
variable of type HMI_STRING, then double quotes must be used. For exemple,
'"hello"' or '"hello"#another comment' match HMI_STRING 'hello'.
Click on widget changes variable value to next value in given list, or to
first one if not initialized to value already part of the list.
