  3. Rework: LegacyFrameAllocator::construct_memory_map 

    The new implementation takes in a list of slices that are used by the
bootloader. It then goes through all regions and checks if they overlap
any of those slices. If so, the region is split and this process is
started recursively until none of the usable regions overlap the memory
used by the bootloader.

  2. New test to check usable memory is writable 

    split out the write check from the lower_memory_free test. Those 2
aren't really related
