This is the sister issue to bitcraze/crazyflie-firmware#623.

There should be a way for the Crazyflie to gracefully shutdown before the nRF51 cuts the power.

The idea is:

  • When the nRF51 want to shut down the system, it sends a packet to the stm32 to request shutdown
  • When the STM32 is ready to shut-down, it sends back a packet
  • If no "ready to shutdown" packets has been received after a short timeout, the power is cut anyway.

Add graceful shutdown support

This will allow the STM32 firmware to wrap up any sensitive operations
like dealing with logging to SD card.

The idea is ...

  ... when the nRF51 want to shut down the system, it sends a packet
      to the stm32 to request shutdown (SYSLINK_SYS_SHUTDOWN_REQUEST)

  ... when the STM32 is ready to shut-down, it sends back a packet
      (SYSLINK_SYS_SHUTDOWN_ACK)

  ... If no "ready to shutdown" packets has been received after a short
      timeout, the power is cut anyway.

Closes #50
