OSX revert fix for i#90083
Part of commit d6f7c94e5c27ba02ff5c3229760c9808cc9b5bea
At least on my current OSX box application based window switching
"just works" "out of the box", even without the code.
With the replacement of the list with a set, the result is a little
bit unexpected and as all the code has a comment "FIXME: lousy
workaround", my fix is simply to drop it.

Unify Reschedule implementation and usage
Application::Reschedule(true) should just process all currently
pending events and ignore all new events generated while processing
them.
This way we also can drop nMaxEvents from the Windows backend. This
limit was also never implemented on OSX and for the KDE4 backend
it's actually impossible to handle single events.
Also changes various call sites to just process all pending events
instead of some made of number of times.

Don't wait-yield non-main threads in the main thread
This prevents blocking the main thread by a yielding non-main thread.
The current solution is to wait on a condition, which is set by the
main thread on wakeup.
