Register a file descriptor for monitoring (call handler upon events). Every fd can have only one handler.

@param mode Thread or signal. @param event_fd File descriptor to set handler for. @param events Events to wait on (UCS_EVENT_SET_EVxxx bits). @param cb Callback function to execute. @param arg Argument to callback. @param async Async context to which events are delivered. If NULL, safety is up to the user.

@return Error code as defined by @ref ucs_status_t.
