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.

This file contains testcases that tend to be related to special cases or less
common commands affecting largefile.

test for pattern matching on 'hg status':

to boost performance, largefiles checks whether specified patterns are

  Invoking status precommit hook
  A a/b/c/d/e.large.txt

  $ hg status -A
  C a/b/c/d/e.large.txt
  C a/b/c/d/e.normal.txt
  C a/b/c/x/y.normal.txt

(2) pattern not related to largefiles: performance boost
  $ hg status -A a/b/c/x

(3) pattern related to largefiles: no performance boost
  $ hg status -A a/b/c/d
  C a/b/c/d/e.large.txt
  C a/b/c/d/e.normal.txt

(4) pattern related to STANDIN (not to largefiles): performance boost
  $ hg status -A .hglf/a
  C .hglf/a/b/c/d/e.large.txt

(5) mixed case: no performance boost
  $ hg status -A a/b/c/x a/b/c/d

Pushing revision #1 causes uploading entity 89e6c98d9288, which is
shared also by largefiles b1, b2 in revision #2 and b in revision #5.

Then, entity 89e6c98d9288 is not treated as "outgoing entity" at "hg
summary" and "hg outgoing", even though files in outgoing revision #2
and #5 refer it.
