Clear stack area below revived continuation.

* unwind.c (revive_cont): Don't just reserve frame_slack
bytes below the continuation for any stack frame, but
clear the bytes to zero. On Cygwin, this fixes a failing
continuation test case. The issue is that the cont_obj
variable in capture_cont lands into this area (implying
it is not captured). When the continuation is revived,
the variable has a garbage value, rather than nil,
as expected.
