Add factory functions to distinguish between when the owner of the File wants to transfer ownership to the new IPC object (adopt) or to send a copy of the same fd to the IPC peer (clone). This behavior is more intuitive than the previous behavior. Previously, an IPC::File would default to a shallow clone of the file descriptor, only *actually* calling dup(2) for the fd when encoding or it into an IPC MessageBuffer. Now the dup(2) for the fd is explicit in the clone_fd factory function.
