Function start

pub(crate) unsafe fn start() -> (&'static Kernel, STM32F3Discovery, &'static Stm32f3xx<'static, Stm32f3xxDefaultPeripherals<'static>>)

Main function.

This is in a separate, inline(never) function so that its stack frame is removed when this function returns. Otherwise, the stack space used for these static_inits is wasted.
