AsyncServerSocket::AcceptCallback::connectionAccepted to NetworkSocket (attempt #2)

Summary:
The file descriptor API here needs to go away, so switch this API to NetworkSocket

It is expected that this commit will cause a number of Open Source projects to temporarily show up as broken. This is due to the fact that not all projects get synced to Github at the exact same time, so the builds may temporarily be fetching an older version of it's dependencies than it needs to :) It should fix itself quickly.
