Add detection of untracked folders to IndexDiffFilter
Decorators need to know whether folders in the working tree contain only
untracked files. This change enhances IndexDiffFilter to report such
folders. This works only together with treewalks which operate in
default traversal mode. For treewalks which process entries in
postorder mode (files are walked before their parent folder is walked)
this detection doesn't work.

Extend IndexDiff to calculate ignored files and folders
IndexDiff was extended to calculate ignored files and folders.
The calculation only considers files that are NOT in the index.
This functionality is required by the new EGit decorator implementation.

Before this change any files in the conflicting set would
also be listed in the the other IndexDiff Sets which is
confusing. With this change a conflicting file will not
be included in any of the other sets.

Add a performance optimized variant of the ANY_DIFF filter
If a treewalk walks also over index and the workingtree then the
IndexDiffFilter filter can be used which works much faster then
the semantically equivalent ANY_DIFF filter. This is because this
filter can better avoid computing SHA-1 ids over the content of
working-tree files which is very costly.
This fix will significantly improve the performance of e.g.
EGit's commit dialog.

Instead of setting a boolean when a difference record is found, return
false from diff() only if all of the collections are empty. When all
of them are empty, no difference was found.

IndexDiff: Use isModified() when comparing index-worktree
The isModified() is more efficient because it can skip over files that
are stat clean, without needing to scan them.
This is useful to efficently work on paths that were already staged
and thus differ between HEAD and the index, but not between the index
and the working tree.

IndexDiff: Clean up tree-index compare for staged files
When comparing the ObjectIds for two tree entries its faster
to use the raw buffer compares over allocating ObjectIds and
then performing equals on their contents.
However, this also needs to consider the raw modes. It is possible
for a path to change modes but not ObjectId (e.g. making a file
executable), and in this case its still a staged change to report back
to the caller.

If the caller really needs the list of files that are flagged as
assume-unchanged (aka assume-valid in the DirCache), we should give
them the complete list and not just those that we wrongly identified
as being modified during diff().
This change is necessary because diff() is slightly broken and is
discovering differences on files that it shouldn't have considered.

The TreeWalk is configured to be recursive, which means subtrees are
never presented to the application. Therefore the working tree file
mode can never be a subtree/subdirectory at this point in the code.

Instead of asking the individual iterators for their path string, use
the TreeWalk's generic getPathString() method. Its just as fast
because it uses the path of the current matching iterator.

allocating the array for 4 isn't a huge waste of memory, but it
does simplify our code.

Its confusing that a new TreeWalk() needs to have reset() invoked
on it before addTree(). This is a historical accident caused by
how TreeWalk was abused within ObjectWalk.
Drop the initial empty tree from the TreeWalk and thus remove a
number of pointless reset() operations from unit tests and some of
the internal JGit code.
Existing application code which is still calling reset() will simply
be incurring a few unnecessary field assignments, but they should
consider cleaning up their code in the future.

This better matches with the name used in the environment
(GIT_WORK_TREE), in the configuration file (core.worktree),
and in our builder object.
Since we are already breaking a good chunk of other code
related to repository access, and this fairly easy to fix
in an application's code base, I'm not going to offer the
wrapper getWorkDir() method.
