When updating smudged entries use a pathfilter to iterate only over
working tree files which have an associated smudged index entry.
Commit dac66672df introduced that we
check and update smudged entries while persisting a dircache. Before
that commit adding a file to git caused file i/o for the index file,
the object database (to store new content) and all files we wanted to
add (to read new content). After that commit we have additionally file
i/o for every file in the working tree (even ignored files).
Especially on windows iterating over the working tree can be very
time consuming. This decreased the performance of persisting a dircache
dramatically (I measured factors 4 to 10 while adding a file to linux
kernel repo). One could easily see this effect when dragging&dropping
modified files in a linux kernel repo in the egit staging view.

I have unfortunately introduced a few bugs in the native Git client
over the years. 1.7.5 is unable to send chunked requests correctly,
resulting in corrupt data at the server. Ban this client whenever
it uses chunked encoding with an error message.
Prior to some more recent versions, git push over HTTP failed to
report status information and error messages due to a race within
the client and its helper process. Check for these bad versions and
send errors as messages before the status report, enabling users
to see the failures on their terminal.

It was easy to create multiple packs with exactly the same name and
same DfsRepositoryDescription in a test, which can poison the
DfsBlockCache. The javadoc for DfsObjDatabase.newPack() explicitly
says pack names should be unique within an entire DFS, so do this by
making the packId AtomicInteger static.
Arguably, test writers shouldn't be doing things like putting
'new DfsRepositoryDescription("test")' in a setUp() method, but that's
a natural thing to do, and we don't document this restriction
anywhere.

When starting a rebase with C Git, there may be empty lines in the
git-rebase-todo file. Before this change, JGit would fail to parse the
file with e.g. the following exception:
JGitInternalException: Unknown or unsupported command "
#", only "pick" is allowed.
This happened when there was an empty line just before the comments,
because the nextSpace would be the one from the comment. Now the empty
lines are ignored by checking for nextSpace < ptr outside of the loop.

Before, the paths to delete were stored in a HashMap, which doesn't have
a particular order. So when e.g. both the file "a/b" and the directory
"a" were to be deleted, it would sometimes try to delete "a" first. This
resulted in a failed path because File#delete() fails when a directory
isn't empty.
With this change, an ArrayList is used for storing the paths to delete.
The list contains the paths in a top-down order, as defined by the order
of processEntry. When the files are deleted, the list is iterated in
reverse, ensuring that all files of a directory are deleted before the
directory itself.

ResolveMerger#mergeImpl() was only returning false (= failed) when there
were unmerged paths. In the case when there were only failing paths, it
returned true.
Because MergeCommand looks at the return value for determining if the
merge failed, it would fall into the successful case there, where it
should instead return a MergeResult with MergeStatus.FAILED.
This change adds a test case for this and makes the ResolveMerger return
false when there are failing paths.
This was discovered while working on fixing bug 354099 and is needed for
its test case.

Whenever a call to JGit returns a Repository the caller should make sure
to call close() on it if he doesn't need it anymore. Since instances of
Repository contain e.g. open FileOutputStreams (for pack files)
forgetting to close the repository can lead to resource leaks.
This was the reason why dozens of the JUnit tests failed on Windows
with "Can't delete file ...." errors.
In LocalDiskRepositoryTestCase.tearDown() we tried to delete the
repositories we used during tests which failed because we had open
FileOutputStreams.
Not only the obvious cases during Clone or Init operations returned
Repositories, but also the new SubModule API created repository
instances. In some places we even forgot to close submodule repositories
in our internal coding.
To see the effects of this fix run the JGit JUnit tests under Windows.
On other platforms it's harder to see because either the leaking
resources don't lead to failing JUnit tests (on Unix you can delete
files with open FileOutputStreams) or the java gc runs differently and
cleans up the resources earlier.

It is not always appropriate to use the .gitmodules file from the
working tree, for example if reading the modules at a specific commit.
And sometimes it is impossible, as in a bare repository.
When using the static factory methods, automatically set up the
appropriate root tree so lazy loading of the config file reads from
the appropriate place. Leave the current behavior of looking in the
working tree as a fallback for the case where walking the index.

All commands should throw a GitAPIException so new exceptions can be
added without breaking the builds of old code, i.e. anyone that calls
a Git API should catch GitAPIException and not just the currently known
exceptions.
Now the only checked exceptions on Git API calls are GitException and
subclasses of it. New checked exceptions that are subclasses of
GitException may be added without breaking the API.
Javadoc for GitAPIException is declared on GitCommand and
inherited to subclasses. JGitInternalException is not explicitly
documented anymore.
Unfortunately this change itself breaks the API. The intention is
that it shall be possible to add new checked subclasses of
GitAPIException without breaking the API.

Previously if a packed-refs file was racily clean then there
was a 2.5 second window in which each call to getPackedRefs
would increment the mod count causing a RefsChangedEvent to be
fired since the FileSnapshot would report the file as modified.
If a RefsChangedListener called getRef/getRefs from the
onRefsChanged method then a StackOverflowError could occur
since the stack could be exhausted before the 2.5 second
window expired and the packed-refs file would no longer
report being modified.
Now a SHA-1 is computed of the packed-refs file and the
mod count is only incremented when the packed refs are
successfully set and the id of the new packed-refs file
does not match the id of the old packed-refs file.
