Skara transition: jfx-dev/rt repo and javafxports/openjdk-jfx sandbox frozen

[Kevin Rushforth]

As announced in this message [1], we are transitioning the official 
openjfx mainline repo from Mercurial (hosted on hg.openjdk.java.net) to 
GIT (hosted on github.com). Effective immediately, the HG 
openjfx/jfx-dev/rt [2] repo is frozen. No more pushes to this repo will 
be accepted. Similarly, no more pull requests will be accepted against 
the GitHub javafxports/openjdk-jfx [3] sandbox repo.

I have one final push to HG which will add the .jcheck/conf file needed 
by Skara [4]. I will do some sanity testing, and then the HG repo will 
be made read-only.

I will send an announcement tomorrow morning when the new GitHub 
openjdk/jfx [5] repo is open for accepting pull requests. In the mean 
time, you can fork and clone the new repo as indicated here [6] to 
prepare for this.

Let me know if you have any questions.
