This commit reworks socket poll implementation to support multiple socket implementations. To achieve that, two ioctl poll helper requests were added: ZFD_IOCTL_POLL_PREPARE and ZFD_IOCTL_POLL_UPDATE. The poll implementation calls ioctl with these requests for each socket requested in the fds table. The first request is responsible for preparing k_poll_event objects for specific socket. It can request to skip waiting in k_poll by returning EALREADY through errno. The latter request is responsible for processing outcome of k_poll for each socket. It can request to retry the k_poll by returning EAGAIN through errno. Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
