JIRA: https://javafx-jira.kenai.com/browse/RT-38074
Webrev: http://cr.openjdk.java.net/~ddehaven/RT-38074/rt.0/ 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. -DrD-
