[Qemu-devel] [PATCH] ui/cocoa.m: Prevent activation clicks from going to guest

[Programmingkid]

When QEMU is brought to the foreground, the click event that activates QEMU
should not go to the guest. Accidents happen when they do go to the guest
without giving the user a change to handle them. Buttons are clicked accidently.
Windows are closed accidently. Volumes are unmounted accidently. This patch
prevents these accidents from happening.
