Add this to ucontext.d:

You probably also need this for core/sys/posix/sys/stat.d

The definition of ucontext_t should be enough. But this code is only
for fibers real threads don't need this support code and should work
fine without it. You probably also need the stat_t definition posted
above to do any kind of IO.
