commands: update debugindex to display more fields

Now debugindex command displays flags and size(revlog.rawsize)
Currently it looks like:

   rev    offset  length   size   base linkrev     p1     p2       nodeid
     0         0    2307   7801      0      0      -1     -1 b6444347c629
     1      2307      77   7841      0      5       0     -1 06763db6de79
