revlog: avoid possible collision between directory and temporary index

Since 6.4, we create a temporary index file to write the split data without
overwriting the inline version too early. However, the store encoding does not
prevent these new `.i.s` file to collide with a directory with the same name.
While the odds for such a collision to happens are fairly low, the collision
would prevent Mercurial from working.

The store encoding have a mitigation solution in place to prevent such
collisions from happening for `.i` and `.d` files, but not for other extensions.
We cannot update this encoding scheme to solve the issue since it would diverge
from older version of Mercurial.

Instead, we create an alternative directory tree dedicated to such files.
The use of the `.i` extension combined with store encoding will prevent
collisions there.

test deleting .hg/bookmarks.current when explicitly updating
to a revision

  $ echo a >> b
  $ hg ci -m.
  $ hg up -q X
  $ test -f .hg/bookmarks.current

try to update to it again to make sure we don't
set and then unset it

  $ hg up -q X
  $ test -f .hg/bookmarks.current

  $ hg up -q 1
  $ test -f .hg/bookmarks.current
  [1]

when a bookmark is active, hg up -r . is
analogous to hg book -i <active bookmark>

  $ hg up -q X
  $ hg up -q .
  $ test -f .hg/bookmarks.current
  [1]

issue 4552 -- simulate a pull moving the active bookmark

  $ hg up -q X
  $ printf "Z" > .hg/bookmarks.current
  $ hg log -T '{activebookmark}\n' -r Z
  Z
  $ hg log -T '{bookmarks % "{active}\n"}' -r Z

test that updating to closed branch head also advances active bookmark

  $ hg commit --close-branch -m "closed"
  $ hg update -q ".^1"
