This is needed to ensure interoperability with the command line: if
the git-rebase-todo file was created manually (by git rebase -i in the
command line), and any commands other than pick are used (reword,
edit, fixup, squash) JGit must abort as it does not understand these
commands yet.
The same is true if an unknown command is found (e.g. due to a typo);
this is the same behavior as shown by the command line.

Always use streaming (for SHA-checksum & collision detection)
when indexing whole blobs, regardless of their size.
Positives:
* benefits of bugfix #312868 will apply to all runtimes, without
additional conf for mem-constrained JVMs (5MB huge for some)
* no byte array allocation
(re-uses readBuffer instead of allocating new full-size array)
* mildly better overall performance
(given the usual blob-does-not-need-collision-checking case)
* removes unnecessary code
Negative:
* doubles the disk IO for a blob comparision
(comparitively rare occurance)
I perf-tested a range of threshold sizes against a random selection
of packfiles I found on my harddrive, the results are here:
https://spreadsheets.google.com/ccc?key=tLCQElyyd2RKN9QevfvgwGQ&hl=en_GB#gid=1
My interpretation of the results is that the streaming size threshold
isn't beneficial (actually seems to be very slightly detrimental) -so
we should just get rid of it. This tallies with some of the comments
Shawn & I had for the default value of streamFileThreshold in the
review for I862afd4c:
http://egit.eclipse.org/r/#patch,sidebyside,2040,2,org.eclipse.jgit/src/org/eclipse/jgit/transport/IndexPack.java
The perf-test code is here: https://gist.github.com/735402
It's a bit scruffy but basically does 10 runs (in randomised order)
for each threshold size on various packfiles, waiting a second
between each pack-indexing to allow GC to catch up. I know it's not
perfect - proper perf testing is hard to do :-)
For convenience provide an option to skip deletion of non-existing
files. Also add some tests for deletion methods in FileUtils.

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.

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

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 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,

Existing application code which is still calling reset() will simply
