RFR: 8344899: Map RT-nnnn bug IDs to JDK-mmmmmmm in JavaFX sources [v2]

[Marius Hanl]

> This PR changes all `RT-XXXX` references to `JDK-XXXXXXX`.
> It also removes all `http://javafx-jira.kenai.com/browse/` occurrences.
> 
> As discussed, this will help a lot when looking up old issues, especially since not everybody know how to do a lookup with the `RT-XXXX` number in the JIRA.
> 
> Thanks to @kevinrushforth who provided the mapping!
> I wrote a small Java program that replaces all the occurrences. This includes the following files:
> - .`java, .css, .m, .h, .cc, .vert, .jsl, .c, .cpp`
