Otherwise interesting things will happen in Cocoa applications, like
infinite event loops that block the NSApplication loop forever.
This was only needed for GNUStep and thus can safely be removed now.
Until gcc and GNUStep properly support Objective-C blocks and other
"new" features of Objective-C we can't properly support them without
making the code much more ugly.

Otherwise when resizing the window you will also get messages like:
class NSConcreteMapTable autoreleased with no pool in place - just leaking
class NSConcreteValue autoreleased with no pool in place - just leaking
class NSConcreteValue autoreleased with no pool in place - just leaking
class __NSCFDictionary autoreleased with no pool in place - just leaking
Need to set the ':' as the reshape method now takes one parameter.
For the story, the GstGLNSView was previously inheriting from
NSOpenGLView which has a reshape function without any parameter.
Now the GstGLNSView inherits from NSView and we re-use the reshape
function manually.
Use the reshape function after being defined. The other way
would have been to declare the reshape function in the header.

Using NSApp directly seems to confuse something, as the compiler
was expecting an id<NSFileManagerDelegate>. Switched to using
[NSApplication sharedApplication], and specified the delegate
protocol on the window class as well.

The visible rect and bounds might be the same as before, but Cocoa
might've changed our viewport without us nothing. This happens if
you hide the view and show it again.
"(NSApplication *)sharedApplication This method also makes a connection
to the window server and completes other initialization"
The implicit thing which is not mentioned is that it required
to be called in the main thread.
Fix a regression introduces by 82b7c915bb
When using with gst-launch, it was not possible to click on the close
cross of the window anymore which is a bit anoying and also because
it's was possible before.
Prior to this commit the GstGLContextCocoaClass was initialized
in the main thread because gst_gl_context_new was called in the
state change function from going from ready to paused.
From this commit this call is done from the streaming thread.
So that the call to [NSApplication sharedApplication];
was not done in the main thread anymore.
We now ensure that by assuming there is a GMainLoop running.
It's for debugging purpose so that's ok to do that. Also
note we already do this assumtion to run app itereations.
The regression had no consequence on the cocoa/videooverlay example
(that should be moved from gst-plugins-gl to -bad) because the
application is responsible for that necessary call.
