match: fix a caseonly rename + explicit path commit on icasefs (issue4768)

The problem was that the former name and the new name are both normalized to the
case in dirstate, so matcher._files would be ['ABC.txt', 'ABC.txt'].
localrepo.commit() calls localrepo.status(), passing along the matcher.  Inside
dirstate.status(), _walkexplicit() simply grabs matcher.files() and processes
those items.  Since the old name isn't present, it is silently dropped.  There's
a fundamental tension here, because the status command should also accept files
that don't match the filesystem, so we can't drop the normalization in status.
The problem originated in baa11dde8c0e.

Unfortunately with this change, the case of the old file must still be specified
exactly, or the old file is again silently excluded.  I went back to
baa11dde8c0e^, and that had the same behavior, so we are no worse off.  I'm open
to ideas from a matcher or dirstate expert on how to fix that half.

This test makes sure that we don't mark a file as merged with its ancestor
when we do a merge.

  $ cat <<EOF > merge
  > import sys, os
  > print "merging for", os.path.basename(sys.argv[1])
  > EOF
  $ HGMERGE="python ../merge"; export HGMERGE

Creating base:

  $ hg init a
  $ cd a
  $ echo 1 > foo
  $ echo 1 > bar
  $ echo 1 > baz
  $ echo 1 > quux
  $ hg add foo bar baz quux
  $ hg commit -m "base"

  $ cd ..
  $ hg clone a b
  updating to branch default
  4 files updated, 0 files merged, 0 files removed, 0 files unresolved

Creating branch a:

  $ cd a
  $ echo 2a > foo
  $ echo 2a > bar
  $ hg commit -m "branch a"

Creating branch b:

  $ cd ..
  $ cd b
  $ echo 2b > foo
  $ echo 2b > baz
  $ hg commit -m "branch b"

We shouldn't have anything but n state here:

  $ hg debugstate --nodates | grep -v "^n"
  [1]

Merging:

  $ hg pull ../a
  pulling from ../a
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 2 changes to 2 files (+1 heads)
  (run 'hg heads' to see heads, 'hg merge' to merge)

  $ hg merge -v
  resolving manifests
  getting bar
  merging foo
  merging for foo
  1 files updated, 1 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

  $ echo 2m > foo
  $ echo 2b > baz
  $ echo new > quux

  $ hg ci -m "merge"

  $ cd ..
