Proposal: Migrate official jfx repo to GitHub + Skara tooling

Hearing no objection, we plan to switch the official jfx repo from the 
existing HG openjfx/jfx-dev/rt [1] repo to the GIT openjdk/jfx [2] repo 
hosted on GitHub on Thursday, September 26, two weeks from today. By way 
of disclaimer, please be aware that the JEP for moving the JDK repos to 
GIT [3] is not yet completed, nor has the follow-on JEP to specify the 
hosting provider for the JDK repos been filed. As such, this should be 
considered "early access", although I don't anticipate further changes.

Here is an overview of the transition timeline. More details, including 
actions that OpenJFX Contributors need to take, will be communicated 
after next week's Oracle Code One.

Now through Tuesday, September 24
* Follow the existing procedures for code reviews: either use a PR 
against the javafxports/openjdk-jfx [4] sandbox repo on GitHub or a 
webrev posted at [5] -- in either case send an RFR email
* Approved fixes will continue to be pushed to the HG openjfx/jfx-dev/rt 
repo by a Committer

Wednesday, September 25
* The HG openjfx/jfx-dev/rt repo will be made read-only (exact time tbd, 
probably around noon Pacific time)
* The javafxports/openjdk-jfx sandbox repo will be "retired" at this 
time. Developers will be responsible for migrating open pull requests to 
openjdk/jfx (I will send out instructions to make this as easy as possible).

Thursday, September 26
* The Skara team will turn off the mirroring of HG openjfx/jfx-dev/rt 
--> GIT openjdk/jfx
* I will push a commit to enable jcheck to the openjdk/jfx repo on GitHub
* The Skara team will enable the Skara tooling
* I will send an announcement that openjdk/jfx is open for pull requests 
on GitHub

Please let me know if there are any questions about the transition.
