New overloaded method TGpioLinuxPin.WaitForInterrupt() with changed Value
Updated Interrupt example with infinite wait
Class constants for TGpioLinuxPin.WaitForInterrupt() timout
INTERRUPT_WAIT_NONE => immediate return (doesnot wait for interrupt)
INTERRUPT_WAIT_INFINTE => wait infinite time until interupt occurs
Fixed Linux interrupt
Method TGpioLinuxPin.WaitForInterrupt() now reads the current value of GPIO pin; otherwise the system call poll() returned because there was already data to be read.
Also the current value is returned in a reliable way.
