/*
* \brief Nut/OS Initialization.
*
* Initializes the memory management and the thread system and starts
* an idle thread, which in turn initializes the timer management.
* Finally the application's main() function is called.
*
* Depending on the compiler, different methods are used to execute this
* function before main() is called.
*
* For ICCAVR the default crtatmega.o startup file is replaced by
* crtnut.o, which calls NutInit instead of main(). This is done
* by adding the following compiler options in the project:
* \code -ucrtnut.o nutinit.o \endcode
*
* For AVRGCC this function is located in section .init8, which is
* called immediately before jumping to main(). NutInit is defined
* as:
* \code
* void NutInit(void) __attribute__ ((naked)) __attribute__ ((section (".init8")));
* \endcode
