This fixes cycles of init/shutdown/init where ecore event types would
become invalid, since they are now stored in a dynamic array rather than
a statically stored array.
The risk here is that if a module of EFL tends to init/shutdown in a
"normal" scenario then the event type array will grow in a leaking
manner. This could be fixed by resetting those event ID's only when the
loop actually exits (EFL_EVENT_DEL on the main loop). I'm not using
EFL_EVENT_DEL in this patch as this would add too many event callbacks
to the main loop object, which may result in slightly slower event calls
to it, affecting the overall performance.
it turns out that xlib is going to copy the complete struct into
something internal. This might lead to the condition that a uninitalized
value might be part of the struct, and when later the struct is read
again the code might do wrong stuff since that value could be set now to
a randomly other meaningfull value.
This turned out on me in e as i could not write any letters like ßöäü,
since that lead to a not returning call to _XReply internal of xlib.
Dugging that showed that xlib was waiting on a reply of a call that
never got executed, and the XEvent it is waiting on just contians a
randomly correct value.
@fix
as per mailing list discussion about dropping xcb support now. it
hasn't been complete for a long time, thus not recommented for being
turned on. as we are moving to a wayland world xcbmakes even less
sense. as agreed, time to clean up a bit and remove a distraction as
well as not well tested code. this also updates po's too.
