Several return values in the constructor of the scheduler were ignored
before, while they should be respected.
I found that bug while strac'ing ardupilot as it failed at some later
point.

This allows to terminate the flight stack nicely, ensuring it returns 0
so init system can check by return code if it terminated nicely or if it
was due to a crash.
This allows to wakeup the thread that is sleeping on Poller::poll()
[ which in our case is an epoll_wait() call ]. This is usually achieved
by using a special signal and using the pwait() variant of the sleeping
function (or using signalfd). However integrating the signal in the
Thread class is more complex than simply use the eventfd syscall which
can serve our needs.
Up until now we rely on Thread objects and variants thereof to be allocated
on heap or embedded in another object that's zero'ed on initialization.
However sometimes it's convenient to be able to use them on stack as
will be the case when writting unit tests.
Initialize all relevant fields to allow them to be used on stack. While
at it, prefer C++11 initialization on Poller since it's only setting the
default (invalid) value.
The only example being built in build_all.sh was CPUInfo and that is
really an APM tool. It will get built further down in when
autotest.py calls build.Examples so we don't need to build it here.
And changing the Replay build to just call make which really means it
will invoke waf as that's what the makefile does.

It is a very simply form of station keeping. If a boat is
loitering on a waypoint and it gets blown off a distance
past the WAYPOINT_RADIUS it will automaticlly drive back to
the waypoint.
