microbit-dal: patch for fiber_wake_on_event



fiber_wake_on_event used to crash after forking a FOB fiber.



It would attempt to obtain a new fiber context, and would place it on the wait queue.

Then when that fiber was paged in, the context of that fiber would not have been

initialised, as the function presumed schedule would be called immediately after

fiber initialisation.



This patch catches that edge case.

Jonathan Austin 1:8aa5cdb4ab67 5 ## Overview
Jonathan Austin 1:8aa5cdb4ab67 6
Jonathan Austin 1:8aa5cdb4ab67 7 The micro:bit runtime provides an easy to use environment for programming the BBC micro:bit in the C/C++ language, written by Lancaster University. It contains device drivers for all the hardware capabilities of the micro:bit, and also a suite of runtime mechanisms to make programming the micro:bit easier and more flexible. These range from control of the LED matrix display to peer-to-peer radio communication and secure Bluetooth Low Energy services. The micro:bit runtime is proudly built on the ARM mbed and Nordic nrf51 platforms.

LancasterUniversity 17:b15c83c64043 9 In addition to supporting development in C/C++, the runtime is also designed specifically to support higher level languages provided by our partners that target the micro:bit. It is currently used as a support library for all the languages on the BBC www.microbit.co.uk website, including the Microsoft Block Editor, Microsoft Touch Develop, Code Kingdoms JavaScript and Micropython languages.
