revlog: define censored flag for revlogng index
This flag bit will be used to cheaply signal censorship presence to upper
layers (exchange, verify). It indicates that censorship metadata is present
but does not attest to the verifiability of that metadata.
For the censorship design, see: http://mercurial.selenic.com/wiki/CensorPlan
