Adding OSAL inotify

[MaciejKaszynski]

Adding an osal layer for inotify.

The INotifyWatcher is exposes an iterator that wraps the reading from the inotify event queue file, new events appear when available and things are blocked with epoll_wait so that we can sleep. This also allows for interruptions for unit tests.
(note I had to do some funky stuff with epoll for this)

Usage:

    auto res = INotifyWatcher::Create();
    auto watcher = std::move(res).value();
    auto watch = watcher.add_watch("/tmp", IN_CREATE);

    for (const INotifyEvent& event : watcher)
    {
        // will block until a new event is present
        // running touch /tmp/test will print test!
        std::cout << event.name << std::endl;
    };

Move to baselibs if eclipse-score/baselibs#420 is done

Probably return statement is missing here.

This code is in posix folder, but I'm not sure if we don't need separate code for Linux and QNX
