`fdSocket` is fairly unsafe, because the socket may be finalized (and therefore closed) while the file descriptor is still being used. `withFdSocket` offers a safer way to use the file descriptor.

As described in #396 and #397, sockets can be incorrectly closed during
acceptorrecv. This is becausefdSocketdoesn't guarantee a reference for the IORef during the operation, letting the Socket to be GC'd.This MR replaces all the uses of
fdSocketwith @treeowl 'swithFdSocketand ensures that sockets are kept during the actions.
