Fix ResolveMerger not to add paths with FileMode 0
When ResolveMerger finds a path where it has to do a content merge it
will try the content merge and if that succeeds it'll add the newly
produced content to the index. For the FileMode of this new index entry
it blindly copies the FileMode it finds for that path in the common base
tree. If by chance the common base tree does not contain this path it'll
try to add FileMode 0 (MISSING) to the index.
One could argue that this can't happen: how can the ResolveMerger
successfully (with no conflicts) merge two contents if there is no
common base? This was due to another bug in ResolveMerger. It failed to
find out that for two files which differ only in the FileMode (e.g. 644
vs. 755) it should not try a content merge.

ReceivePack (and PackParser) can be configured with the
maxObjectSizeLimit in order to prevent users from pushing too large
objects to Git. The limit check is applied to all object types
although it is most likely that a BLOB will exceed the limit. In all
cases the size of the object header is excluded from the object size
which is checked against the limit as this is the size of which a BLOB
object would take in the working tree when checked out as a file.
When an object exceeds the maxObjectSizeLimit the receive-pack will
abort immediately.
Delta objects (both offset and ref delta) are also checked against the
limit. However, for delta objects we will first check the size of the
inflated delta block against the maxObjectSizeLimit and abort
immediately if it exceeds the limit. In this case we even do not know
the exact size of the resolved delta object but we assume it will be
larger than the given maxObjectSizeLimit as delta is generally only
chosen if the delta can copy more data from the base object than the
delta needs to insert or needs to represent the copy ranges. Aborting
early, in this case, avoids unnecessary inflating of the (huge) delta
block.
Unfortunately, it is too expensive (especially for a large delta) to
compute SHA-1 of an object that causes the receive-pack to abort.
This would decrease the value of this feature whose main purpose is to
protect server resources from users pushing huge objects. Therefore
we don't report the SHA-1 in the error message.

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.

Deprecate GitIndex more by using only DirCache internally.
This includes merging ReadTreeTest into DirCacheCheckoutTest and
converting IndexDiffTest to use DirCache only. The GitIndex specific
T0007GitIndex test remains.
GitIndex is deprecated. Let us speed up its demise by focusing the

This also add explicit deprecation comments to methods that depend

Allow detecting which files were renamed during a revwalk
The egit history view shows the files associated with a commit by using

Since we replaced GitIndex by DirCache JGit didn't fire
IndexChangedEvents anymore. For EGit this still worked with a high
latency since its RepositoryChangeScanner which is scheduled to
run each 10 seconds fires the event in case the index changes.
This scanner is meant to detect index changes induced by a different
process e.g. by calling "git add" from native git.
When the index is changed from within the same process we should fire
the event synchronously. Compare the index checksum on write to index
checksum when index was read earlier to determine if index really
changed. Use IndexChangedListener interface to keep DirCache decoupled
from Repository.

Fix status in index entries after checkout of paths
The checkout command was producing an inconsistent state of the index
which even confuses native git. The content sha1 of the touched index
entries was updated, but the length and the filemode was not updated.
Later in coding the index entries got automatically corrected (through
Dircache.checkoutEntry()) but the correction was after persisting the
index to disk. So, the correction was lost and we ended up with an index
where length and sha1 don't fit together.
A similar problem is fixed with "lastModified" of DircacheEntry. When
checking out a path without specifying an explicit commit (you want to
checkout what's in the index) the index was not updated regarding
lastModified. Readers of the index will think the checked-out
file is dirty because the file has a younger lastmodified then what's
in the index.

The client's use of UnionInputStream was broken when combined with a
8192 byte buffer used by PackParser. A smart HTTP client connection
always pushes in the execute stateless RPC input stream after the
data stream has ended from the remote peer. At the end of the pack,
PackParser asked to fill a 8192 byte buffer, but if only e.g. 1000
bytes remained UnionInputStream went to the next stream and asked
it for input, which triggered a new RPC, and failed because there
was nothing pending in the request buffer.
Change UnionInputStream to only return what it consumed from a
single InputStream without invoking the next InputStream, just in
case that second InputStream happens to be one of these magical
ones that generates an RPC invocation.

Fix reading of ref names containing characters that sort before /
A set of ref names like ('a/b' and 'a+b') would cause the RefDirectory
to think that the set of refs have changed because it traversed the
'a' directory in the subtree before looking at 'a+b', but it then
compared with the know refs which are sorted with 'a+b' first.
Fix this by traversing the refs tree in another order. Treat a directory
as if they ends with a '/' before deciding on the order to traverse
the refs tree.
