[8u40] Review request: RT-38074: [macosx] Separate QTKit platform code from core media code so it can be removed for MAS

[David DeHaven]

JIRA Issue:
https://javafx-jira.kenai.com/browse/RT-38074

Latest webrev:
http://cr.openjdk.java.net/~ddehaven/RT-38074/rt.2/

Removed new makefile (eyesore), cleaned up/enhanced existing Makefile, fixed a compiler warning.

Last iteration hopefully, I let it bake for 12 hours and haven't had the urge to change anything ;)

> I moved OSXPlatform and OSXMediaPlayer code back to jfxmedia, since it was meant to be an abstraction point for using either QTKit or AVFoundation in the first place.

>> Belay that review.. I have some (significant) changes to make, in preparation for the larger task of implementing the AVFoundation based code.

>>> This change moves the QTKit based media platform code into it's own dylib. NativeMediaManager had to be modified to allow detection of the new library to determine if the platform was available or not. There may be a slight performance impact due to loading the native libs sooner, but the bulk of the initialization is still done at a later time.
