Review request for 7124217: [macosx] key events are posted to the event queue twice

[Anton V. Tarasov]

Hello,

Please review a fix for 7124217.

webrev: http://cr.openjdk.java.net/~ant/7124217/webrev.0/

Eliminating old code. No need to post key events via invokeLater,
they should be posted directly to the queue as it conforms to AWT
architecture.

Checked that the fix doesn't cause regressions with the focus reg tests.

Thanks,
Anton.
