icasefs: disuse length check against un-normcase()-ed filenames

this patch disuses length check against un-normcase()-ed filenames
gotten by "os.listdir()", because there is no assurance that
filesystem stores filenames normalized except in letter case, even
though some case insensitive filesystems (in some environment, for
some language setting) store them in such manner.

Create a repo with some stuff in it:

  $ hg init a
  $ cd a
  $ echo a > a
  $ echo a > d
  $ echo a > e
  $ hg ci -qAm0
  $ echo b > a
  $ hg ci -m1 -u bar
  $ hg mv a b
  $ hg ci -m2
  $ hg cp b c
  $ hg ci -m3 -u baz
  $ echo b > d
  $ echo f > e
  $ hg ci -m4
  $ hg up -q 3
  $ echo b > e
  $ hg branch -q stable
  $ hg ci -m5
  $ hg merge -q default --tool internal:local
  $ hg branch -q default
  $ hg ci -m6

Need to specify a rev:

  $ hg graft
  abort: no revisions specified
  [255]

Can't graft ancestor:

  $ hg graft 1 2
  skipping ancestor revision 1
  skipping ancestor revision 2
  [255]

Can't graft with dirty wd:

  $ hg up -q 0
  $ echo foo > a
  $ hg graft 1
  abort: outstanding uncommitted changes
  [255]
  $ hg revert a

Graft a rename:

  $ hg graft 2 -u foo
  grafting revision 2
  merging a and b to b
  $ hg export tip --git
  # HG changeset patch
  # User foo
  # Date 0 0

  # Parent  68795b066622ca79a25816a662041d8f78f3cd9e

  diff --git a/a b/b
  rename from a
  rename to b
  --- a/a
  +++ b/b
  @@ -1,1 +1,1 @@
  -a
  +b

Look for extra:source

  $ hg log --debug -r tip
