Migrate antiIntersectionDelay to asyncore

- implemented by ignoring getdata during the delay rather than sleeping
as it was in the threaded model
- it can happen that a valid getdata request is received during the
delay. A node should be implemented in a way that retries to download,
that may not be the case with older PyBitmessage versions or other
implementations
