Signalfd support
Note that the exact semantics for these signalfds are slightly different from
Linux. These signalfds are bound to the process at creation time. Reads, polls,
etc. are all associated with signals directed at that task. In Linux, all
signalfd operations are associated with current, regardless of where the
signalfd originated.
In practice, this should not be an issue given how signalfds are used. In order
to fix this however, we will need to plumb the context through all the event
APIs. This gets complicated really quickly, because the waiter APIs are all
netstack-specific, and not generally exposed to the context. Probably not
worthwhile fixing immediately.
