o Minor bugfixes (dirauth):
- Directory authorities stop voting a consensus "Measured" weight
for relays with the Authority flag. Now these relays will be
considered unmeasured, which should reserve their bandwidth
for their dir auth role and minimize distractions from other
roles. In place of the "Measured" weight, they now include a
"MeasuredButAuthority" weight (not used by anything) so the
bandwidth authority's opinion on this relay can be recorded for
posterity. Lastly, remove the AuthDirDontVoteOnDirAuthBandwidth
torrc option which never worked right. Fixes bugs 40698 and 40700;
bugfix on 0.4.7.2-alpha.
