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.

Differential Revision: https://phab.mercurial-scm.org/D10305

Test attempting a narrow clone against a server that doesn't support narrowhg.

  $ . "$TESTDIR/narrow-library.sh"

  $ hg init master
  $ cd master

  $ for x in `$TESTDIR/seq.py 10`; do
  >   echo $x > "f$x"
  >   hg add "f$x"
  >   hg commit -m "Add $x"
  > done

  $ hg serve -a localhost -p $HGPORT1 --config extensions.narrow=! -d \
  >    --pid-file=hg.pid
  $ cat hg.pid >> "$DAEMON_PIDS"
  $ hg serve -a localhost -p $HGPORT2 -d --pid-file=hg.pid
  $ cat hg.pid >> "$DAEMON_PIDS"

Verify that narrow is advertised in the bundle2 capabilities:

  $ cat >> unquote.py <<EOF
  > from __future__ import print_function
  > import sys
  > if sys.version[0] == '3':
  >     import urllib.parse as up
  >     unquote = up.unquote_plus
  > else:
  >     import urllib
  >     unquote = urllib.unquote_plus
  > print(unquote(list(sys.stdin)[1]))
  > EOF
  $ echo hello | hg -R . serve --stdio | \
  >   "$PYTHON" unquote.py | tr ' ' '\n' | grep narrow
  exp-narrow-1

  $ cd ..

  $ hg clone --narrow --include f1 http://localhost:$HGPORT1/ narrowclone
  requesting all changes
  abort: server does not support narrow clones

Make a narrow clone (via HGPORT2), then try to narrow and widen
into it (from HGPORT1) to prove that narrowing is fine and widening fails
gracefully:
  $ hg clone -r 0 --narrow --include f1 http://localhost:$HGPORT2/ narrowclone

  looking for local changes to affected paths

  $ hg tracked --addinclude f1 http://localhost:$HGPORT1/
  nothing to widen or narrow

  $ hg tracked --addinclude f9 http://localhost:$HGPORT1/

  abort: server does not support narrow clones
