phase: add an archived phase

This phase allows for hidden changesets in the "user space". It differs from
the "internal" phase which is intended for internal by-product only. There
have been discussions at the 4.8 sprint to use such phase to speedup cleanup
after history rewriting operation.

Shipping it in the same release as the 'internal-phase' groups the associated
`requires` entry. The important bit is to have support for this phase in the
earliest version of mercurial possible. Adding the UI to manipulate this new
phase later seems fine.

The current plan for archived usage and user interface are as follow. On a
repository with internal-phase on and evolution off:

* history rewriting command set rewritten changeset in the archived phase.
  (This mean updating the cleanupnodes method).
* keep `hg unbundle .hg/strip-backup/X.hg` as a way to restore changeset for
  now
  (backup bundle need to contains phase data)
* [maybe] add a `hg strip --soft` advance flag
  (a light way to expose the feature without getting in the way of a better
  UI)

Mercurial 4.8 freeze is too close to get the above in by then.

We don't introduce a new repository `requirement` as we reuse the one
introduced with the 'archived' phase during the 4.8 cycle.

initial setup

  $ cat << EOF >> $HGRCPATH
  > [ui]
  > ssh="$PYTHON" "$TESTDIR/dummyssh"
  > EOF

repository itself is non-readable
---------------------------------

  $ hg init no-read
  $ hg id ssh://user@dummy/no-read
  000000000000
  $ chmod a-rx no-read

  $ hg id ssh://user@dummy/no-read
  remote: abort: Permission denied: *$TESTTMP/no-read/.hg* (glob)
  abort: no suitable response from remote hg!
  [255]

special case files are visible, but unreadable
----------------------------------------------

This is "similar" to the test above, but the directory is "traversable". This
seems an unexpected case in real life, but we test it anyway.

  $ hg init other
  $ hg id ssh://user@dummy/other
  000000000000
  $ for item in `find other | sort -r` ; do
  >     chmod a-r $item
  > done

  $ hg id ssh://user@dummy/other
  remote: abort: Permission denied: $TESTTMP/other/.hg/requires
  abort: no suitable response from remote hg!
  [255]

directory toward the repository is read only
--------------------------------------------

  $ mkdir deep
  $ hg init deep/nested

  $ hg id ssh://user@dummy/deep/nested
  000000000000

  $ chmod a-rx deep

  $ hg id ssh://user@dummy/deep/nested
  remote: abort: Permission denied: *$TESTTMP/deep/nested/.hg* (glob)
  abort: no suitable response from remote hg!
  [255]

repository has wrong requirement
--------------------------------

  $ hg init repo-future
  $ hg id ssh://user@dummy/repo-future
  000000000000
  $ echo flying-car >> repo-future/.hg/requires
  $ hg id ssh://user@dummy/repo-future
  remote: abort: repository requires features unknown to this Mercurial: flying-car!
  remote: (see https://mercurial-scm.org/wiki/MissingRequirement for more information)
  abort: no suitable response from remote hg!
