af8862b2a2445d0110f3b3125c1a41fbb5934123 Improve Cocoa modifier key handling
I had two problems with QEMU on macOS:
1) Sometimes when alt-tabbing to QEMU it would act as if the 'a' key
was pressed so I'd get 'aaaaaaaaa....'.
2) Using Sikuli to programatically send keys to the QEMU window text
like "foo_bar" would come out as "fooa-bar".
They looked similar and after much digging the problem turned out to be
the same. When QEMU's ui/cocoa.m received an NSFlagsChanged NSEvent it
looked at the keyCode to determine what modifier key changed. This
usually works fine but sometimes the keyCode is 0 and the app should
instead be looking at the modifierFlags bitmask. Key code 0 is the 'a'
key.
I added code that handles keyCode == 0 differently. It checks the
modifierFlags and if they differ from QEMU's idea of which modifier
keys are currently pressed it toggles those changed keys.
This fixes my problems and seems work fine.
