revlog: always enable generaldelta on version 2 revlogs

This commit starts the process of diverging version 2 revlogs
from version 1 revlogs.

generaldelta is a useful feature and has been enabled by
default for ages. I can't think of a good reason why the
feature should be disabled. Yes, it is true changelogs
today don't have generaldelta enabled. But that's because
they don't have delta chains enabled, so generaldelta makes
no sense there.

This commit makes generaldelta always enabled on version 2
revlogs.

As part of this, one-off code in changelog.py mucking with
revlog.version had to be made conditional on the revlog
version, as we don't want to change revlog feature
flags on version 2 revlogs. The fact this code exists
is horrible and stems from revlog options being shared by
the opener. We probably want a better API here. But that can
wait for another patch.

  $ hg rm a
  $ hg st
  R a
  ? a.orig

excluded file shouldn't be added even if it is explicitly specified

  $ hg add a.orig -X '*.orig'
  $ hg st

Forgotten file can be added back (as either clean or modified)

  $ hg forget b

forget and get should have the right order: added but missing dir should be
forgotten before file with same name is added

  $ hg add d
  $ hg ci -md
  $ hg rm d
  $ mkdir d
  $ echo a > d/a
  $ hg add d/a
