dirstate: preserve path components case on renames (issue3402)

The original issue was something like:

  $ hg init repo
  $ cd repo
  $ mkdir D
  $ echo a > D/a
  $ hg ci -Am adda
  adding D/a
  $ mv D temp
  $ mv temp d
  $ echo b > d/b
  $ hg add d/b
  adding D/b
  $ hg ci -m addb
  $ hg mv d/b d/c
  moving D/b to d/c
  $ hg st
  A d/c
  R D/b

Here we expected:

  A D/c
  R D/b

the logic being we try to preserve case of path components already known in the
dirstate. This is fixed by the current patch.

Note the following stories are not still not supported:

Changing directory case
  $ hg mv D d
  moving D/a to D/D/a
  moving D/b to D/D/b
  $ hg st
  A D/D/a
  A D/D/b
  R D/a
  R D/b

or:

  $ hg mv D/* d
  D/a: not overwriting - file exists
  D/b: not overwriting - file exists

And if they were, there are probably similar issues with diffing/patching.
