    lib: introduce the interface to observables · f27fc993
    Philippe Gerum authored
    Since ABI 23, the core provides the new observable element, which
    enables the observer design pattern. Any EVL thread is in and of
    itself an observable which can be monitored for events too.
    As a by-product, the poll interface can now be given a user-defined
    opaque data when subscribing file descriptors to poll elements, which
    the core passes back on return to evl_poll().
