iOS: delay callbacks to UITextInput to avoid recursion

If the application calls "reset" or "commit" on the input
method (or forces active focus on some other item) from a text
changed or key pressed handler, iOS will sometimes throw
an exception. It does so because we try to change the state
of UITextInput (by calling textDidChange) while processing a
callback from the same place (insertText).

Optimally this should not happen since we would normally
post such events to Qt, not send them directly. But with
text input we cannot do this since UITextInput expects us
to update immediately upon receiving text input callbacks.
If not, word completion and spell checking will stop working.

This change will guard against recursive callbacks by delaying
callbacks to UITextInput when text/selection/first responder
changes.

iOS: enable QUIView to be first responder without opening the keyboard

When a UIView becomes first responder, the keyboard will open as well
if the view implements the protocol UITextInput. It turns out that
we can override the static interface declaration runtime by
overriding - (BOOL)conformsToProtocol:(Protocol *)protocol
This means that we can choose to say that we implement the protocol
when, and only when, the keyboard should be visible. And further, we
can then allow QUIView to become first responder without opening
the keyboard. This will make things easier later when implementing
support for native menus that use the responder chain for
delivering menu actions.
