<AWT Dev> [9] Review Request: 8037099 [macosx] Remove all references to GC from native OBJ-C code

[Petr Pchelko]

Hello, AWT Team.

Please review a huge but simple cleanup fix.

The bug: https://bugs.openjdk.java.net/browse/JDK-8037099
The fix: http://cr.openjdk.java.net/~pchelko/9/8037099/webrev.01

Now the Objective-C Garbage Collector is completely deprecated and we do not use it and will never use. But we still have some code that was used for GC. 
The problem is that under GC retain/release is not the same as CFRetain/CFRelease, but now it's absolutely the same.

I've replaced all CFRetain/CFRelease to retain/release where possible, deleted the pattern CFRetain(o); [o release]; and removed finalize overrides. 
I know that in some places retain is not needed. But in this fix I've left it as is, because it's only a preparation for a big-native-memory-management-fix I'm preparing.

Thank you. 
With best regards. Petr.
