revlog: move the details of revlog "v2" index inside revlog.utils.constants

the revlog module is quite large and this kind of format information would handy
for other module. So let us start to gather this information about the format in
a more appropriate place.

We update various reference to this information to use the new "source of truth"
in the process.

Test version

  Byteify strings * (glob)

Test in-place

  $ cat > testfile.py <<EOF
  > obj['test'] = b"1234"
  > mydict.iteritems()
  > EOF
  $ byteify_strings testfile.py -i
  $ cat testfile.py

Test with dictiter

  $ cat > testfile.py <<EOF

  > mydict.iteritems()
  > EOF

Test kwargs-like objects

Test multi-line alignment
