"Assume unchanged" git: do not set CE_VALID with --refresh

When working with automatic assume-unchanged mode using
core.ignorestat, setting CE_VALID after --refresh makes things
more cumbersome to use.  Consider this scenario:

 (1) the working tree is on a filesystem with slow lstat(2).
     The user sets core.ignorestat = true.

 (2) "git checkout" to switch to a different branch (or initial
     checkout) updates all paths and the index starts out with
     "all clean".

 (3) The user knows she wants to edit certain paths.  She uses
     update-index --no-assume-unchanged (we could call it --edit;
     the name is inmaterial) to mark these paths and starts
     editing.

 (4) After editing half of the paths marked to be edited, she
     runs "git status".  This runs "update-index --refresh" to
     reduce the false hits from diff-files.

 (5) Now the other half of the paths, since she has not changed
     them, are found to match the index, and CE_VALID is set on
     them again.

For this reason, this commit makes update-index --refresh not to
set CE_VALID even after the path without CE_VALID are verified
to be up to date.  The user still can run --really-refresh to
force lstat() to match the index entries to the reality.

"Assume unchanged" git

This adds "assume unchanged" logic, started by this message in the list
discussion recently:

<Pine.LNX.4.64.0601311807470.7301@g5.osdl.org>

This is a workaround for filesystems that do not have lstat()
that is quick enough for the index mechanism to take advantage
of.  On the paths marked as "assumed to be unchanged", the user
needs to explicitly use update-index to register the object name
to be in the next commit.

You can use two new options to update-index to set and reset the
CE_VALID bit:

git-update-index --assume-unchanged path...
git-update-index --no-assume-unchanged path...

These forms manipulate only the CE_VALID bit; it does not change
the object name recorded in the index file.  Nor they add a new
entry to the index.

When the configuration variable "core.ignorestat = true" is set,
the index entries are marked with CE_VALID bit automatically
after:

 - update-index to explicitly register the current object name to the
   index file.

 - when update-index --refresh finds the path to be up-to-date.

 - when tools like read-tree -u and apply --index update the working
   tree file and register the current object name to the index file.

The flag is dropped upon read-tree that does not check out the index
entry.  This happens regardless of the core.ignorestat settings.

Index entries marked with CE_VALID bit are assumed to be
unchanged most of the time.  However, there are cases that
CE_VALID bit is ignored for the sake of safety and usability:

 - while "git-read-tree -m" or git-apply need to make sure
   that the paths involved in the merge do not have local
   modifications.  This sacrifices performance for safety.

 - when git-checkout-index -f -q -u -a tries to see if it needs
   to checkout the paths.  Otherwise you can never check
   anything out ;-).

 - when git-update-index --really-refresh (a new flag) tries to
   see if the index entry is up to date.  You can start with
   everything marked as CE_VALID and run this once to drop
   CE_VALID bit for paths that are modified.

Most notably, "update-index --refresh" honours CE_VALID and does
not actively stat, so after you modified a file in the working
tree, update-index --refresh would not notice until you tell the
index about it with "git-update-index path" or "git-update-index
--no-assume-unchanged path".

This version is not expected to be perfect.  I think diff
between index and/or tree and working files may need some
adjustment, and there probably needs other cases we should
automatically unmark paths that are marked to be CE_VALID.

But the basics seem to work, and ready to be tested by people
who asked for this feature.

   1. refuses to run if $GIT_DIR/MERGE_HEAD exists, and reminds

   2. refuses to run if named paths... are different in HEAD and

      temporary index.

   5. does the same updates of the paths... from the working
      tree to the real index.

   6. makes a commit using the temporary index that has the
      current HEAD as the parent, and updates the HEAD with this
      new commit.

 - "git commit --all" can run from a subdirectory, but it updates
   the index with all the modified files and does a whole tree
   commit.

 - In all cases, when the command decides not to create a new
