HEADS UP: freebsd-ports hashes were all changed

[Ulrich Spörlein]

Hi folks, bad news

While carving out the history of the access and mentors file (we want to 
retain that for historical analysis, which people seem to do from time 
to time), I overlooked that fact that the previous runs for ports did 
contain all of CVSROOT, but the new one, by necessity would not contain 
CVSROOT/{access,mentors}, in fact, I dropped the whole CVSROOT prefix 
from the latest rules file. It should never have been there in the first 
place. :(

All that is to say that this of course means all the git commit hashes 
for the ports tree have changed. Oops.

Sorry about that, please let me know if you need help in transplanting 
your work from old hashes to new hashes.

Cheers
Uli
