I added a comment about using an ifdef for `GSTREAMER_LITE` in one of the modified files (the others are fine, since those files are entirely FX_specific).

One other question: do you need any changes in [ConnectionHolder.java](https://github.com/openjdk/jfx/blob/c334ba810293683b7e510a91be3496f7a872c574/modules/javafx.media/src/main/java/com/sun/media/jfxmedia/locator/ConnectionHolder.java)? That class checks for URL scheme to determine whether a URL is seekable.

modules/javafx.media/src/main/native/gstreamer/gstreamer-lite/gstreamer/gst/gst.c line 125:

I think this should also be qualified by `GSTREAMER_LITE` to indicate that it is a JavaFX-specific modification.
