The coroutine entry() return value must be passed via the caller->data,
since coroutine_swap() returns from->data. (this is needed because
coroutine_swap() argument is used both to return from entry() or to send
data to a running coroutine)
When leaving a coroutine, clear its caller.
Return correct coroutine_self() before other coroutine are initialized.
