[cdt-dev] Releng changes

[Doug Schaefer <cdtdoug@xxxxxxxxx>]

Hey gangs from CDT and TCF. Now that EDC is turned off for Juno, there
is no longer any need to build TCF as part of the CDT build. I am
working on separating the two so that they can be run independently.
Each build will sign and post their own artifacts. cdt-master which
was doing this now will also be turned off.

I will also put in the necessary changes so that the train build will
pick up TCF from a new home. This is required by the Linux Tools
project. The new home will be a new directory created up at
downloads.eclipse.org/tools/tcf (once I get the file perms fixed to
allow me to create it).

We'll likely have a few broken builds this week as I get this going.
So I figured I'd warn you :).

Also, this is for Juno and forward. I will leave the Indigo releng
system in place so that it can be built as is.

Let me know if you have any questions about this.
Thanks,
Doug.
