  1. Fix memory corruption caused by GC-invisible coroutine stacks 

    Crucially this introduces BoehmGCStackAllocator, but it also
adds a bunch of wiring to avoid making libutil depend on bdw-gc.

Part of the solutions for NixOS#4178, NixOS#4200

  2. BoehmGCStackAllocator: increase stack size to 8MB 

    The default stack size was not based on the normal stack size and
was too small.
