First steps in make signals more abstract from the underlying mechanism; replace epoll with poll.

We now don't assume that a signal equals a single fd (eventfd on Linux).
The next step would be to create a version of signal.c that uses a pipe
internally, so it can be used on other platforms, like *BSD.

This is also the reason epoll was replaced with poll in uplink.c
