For --continue, the Rebase command asserts that there are no unmerged
paths in the current repository. Then it checks if a commit is needed.
If yes, the commit message and author are taken from the author_script
and message files, respectively, and a commit is performed before the
next step is applied.
For --skip, the workspace is reset to the current HEAD before applying
the next step.
Includes some tests and a refactoring that extracts Strings in the
code into constants.

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.

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.

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.

To improve runtime performance, caching the WorkingTreeOptions inside
of the Config object using the Config.SectionParser API allows
the WorkingTreeOptions to be accessed more efficiently whenever a
FileTreeIterator is constructed for the Repository.
Instead of passing the filemode handling option into isModified(),
the WorkingTreeIterator should always honor whatever setting has
been configured in this repository, as defined by its own copy of
the WorkingTreeOptions. This simplifies all of the callers as they
no longer need to lookup core.filemode on their own.
A few locations were changed from always using a hardcoded "true"
on the file mode to passing what is actually configured in the
repository. This is a behavior change, but corrects what should be
considered to be bugs as the core.filemode variable wasn't always
being used.

When indexing large blobs that are stored whole (non-delta form),
avoid allocating the entire blob in memory and instead stream it
through the SHA-1 checksum computation. This reduces the size
of memory required by IndexPack when processing very big blobs,
such as a 500 MiB uncompressable binary.
If the large blob already exists in the local repository, its
contents needs to be compared byte-for-byte after the entire pack
has been indexed, to ensure there isn't an unexpected SHA-1 collision
which may result in later data corruption. This compare is performed
as a streaming compare, again avoiding the large object allocation.
This change doesn't improve on memory utilization for large objects
stored as deltas. The change also doesn't improve handling for
any large commits, trees or annotated tags. There isn't much to
be done here for those objects, because they need to be passed down
to the ObjectChecker as a byte[]. Fortunately it isn't common for
these object types to be that large,

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.

Currently the following can happen in LockFile.commit: deletion of the
original file succeeds but renaming fails afterwards. In this case the
original file (e.g. branch file in refs/heads) is lost.
To workaround the issue the same retry logic as for file deletion is
applied to file renaming.
