It's time to merge new-ra branch into mainline

[Bradley Lucier]

It's time to merge the new-ra branch into mainline.

We've gone through two major releases (3.3 and 3.4) with -fnew-ra 
"experimental" and without even bugfixes being merged.  There are bugs 
in bugzilla reported against various mainlines that have been fixed on 
-fnew-ra.  new-ra will get more testing and will perhaps attract more 
hacking attention if it's part of mainline.

And the end of mainline stage 1 is coming up fast, and I don't think we 
should wait another 6 or 8 months to see this.
