Enable and fix 'Should be tagged with @Override' warning
Set missingOverrideAnnotation=warning in Eclipse compiler preferences
which enables the warning:
The method <method> of type <type> should be tagged with @Override
since it actually overrides a superclass method
Justification for this warning is described in:
http://stackoverflow.com/a/94411/381622
Enabling this causes in excess of 1000 warnings across the entire
code-base. They are very easy to fix automatically with Eclipse's
"Quick Fix" tool.
Fix all of them except 2 which cause compilation failure when the
project is built with mvn; add TODO comments on those for further
investigation.

Merge FileTreeIteratorJava7Test into FileTreeIteratorTest
JGit now requires Java 8, so it is no longer necessary to have a
separate class for Java 7 specific tests. Remove it and merge its
tests into the existing FileTreeIteratorTest.
FileTreeIteratorTest has an @Before annotated method that sets up
some files in the git, which breaks the tests which have assumptions
on the file names. Add adjustments.

This fixes the tests failed in JDK8.
FS uses java.nio API to get file attributes. The timestamps obtained
from that API are more precise than the ones from
java.io.File#lastModified() since Java8.
This difference accidentally makes JGit detect newly added files as
smudged. Use the precised timestamp to avoid this false positive.

This commit introduces a FileModeStrategy to
the FileTreeIterator class. This provides a way to
allow different modes of traversing a file tree;
for example, to control whether or not a nested
.git directory should be treated as a gitlink.

Entries should only be written to the working tree managed by the

Callers should manage the ObjectReader, as this allows the JGit library to cache
context relevant information across files checked out at the same time. If the
caller only has one file to checkout, it should still explicitly manage the life
span of the ObjectReader.

Fix FileTreeIteratorTest#testIsModifiedFileSmudged() on Windows
This would be a problem for any OS where Java lets the subscond
part through to the File API. The fix is to force the timetamp
of the index rather than trusting it to just happen to be right.

The change includes comparing symbolic links between disk and index,
adding symbolic links to the index, creating/modifying links on
checkout. The behavior is controlled by the core.symlinks setting, just
as C Git does. When a new repository is created core.symlinks will be
set depending on the capabilities of the operating system and Java
runtime.
If core.symlinks is set to true, the assumption is that symlinks are
supported, which may result in runtime errors if this turns out not to
be the case.
Measuring the cost of jgit status on a repository with ~70000 files,
of which ~30000 are tracked reveals a penalty of about 10% for using
the Java7 (really NIO2) support module.

Revert "Fix for core.autocrlf=input resulting in modified file..."
This reverts commit 1def0a1257.
We found this fix uncovers problems with unsmudged DirCacheEntry's. This
surfaced because egit's ui test CreatePatchActionTest failed since jgit
computes a wrong status. JGit doesn't detect modified content in now
unsmudged entries. Hence revert this change until these problems are
fixed.

Attempt to stabilize FileTreeIterator test on Windows

Fix for Iff768422c, use offset 0 when going back to work tree iterator
In Iff768422c the offset used for the content id was fixed to use the
offset that applied to the dircache iterator. Unfortunately the index
for the dircache content id offset stuck for entries that were not in
the index. Few caller probably cared about that, unless it actually
caused an ArrayIndexOutOfBoundsException.

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.

Smudge index entries on first write (too), as well when reading
That happens when the index and a new file is created within the same
second and becomes a problem if we then modify the newly created file
within the same second after adding it to the index. Without smudging
JGit will, on later reads, think the file is unchanged.
The accompanying test passed with the smuding on read.

Eclipse has some problem re-running single JUnit tests if
the tests are in Junit 3 format, but the JUnit 4 launcher
is used. This was quite unnecessary and the move was not
completed. We still have no JUnit4 test.
This completes the extermination of JUnit3. Most of the
work was global searce/replace using regular expression,
followed by numerous invocarions of quick-fix and organize
imports and verification that we had the same number of
tests before and after.
- Annotations were introduced.
- All references to JUnit3 classes removed
- Half-good replacement for getting the test name. This was
needed to make the TestRngs work. The initialization of
TestRngs was also made lazily since we can not longer find
out the test name in runtime in the @Before methods.
- Renamed test classes to end with Test, with the exception
of TestTranslateBundle, which fails from Maven
- Moved JGitTestUtil to the junit support bundle

Do not rely on filemode differences in case of symbolic links
When checking whether a file in the working tree has been modified -
WorkingTreeIterator.isModified() - we should not trust the filemode
in case of symbolic links, but check the timestamp and also the
content, if requested. Without this fix symlinks will always be shown
in EGit as modified files on Windows systems.

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.

Perform automatic CRLF to LF conversion during WorkingTreeIterator
WorkingTreeIterator now optionally performs CRLF to LF conversion for
text files. A basic framework is left in place to support enabling
(or disabling) this feature based on gitattributes, and also to
support the more generic smudge/clean filter system. As there is
no gitattribute support yet in JGit this is left unimplemented,
but the mightNeedCleaning(), isBinary() and filterClean() methods
will provide reasonable places to plug that into in the future.
[sp: All bugs inside of WorkingTreeIterator are my fault, I wrote
most of it while cherry-picking this patch and building it on
top of Marc's original work.]

We don't actually need a Repository object here, just an ObjectReader
that can load content for us. So change the API to depend on that.
However, this breaks the asCommit and asTag legacy translation methods
on RevCommit and RevTag, so we still have to keep the Repository
inside of RevWalk for those two types. Hopefully we can drop those in
the future, and then drop the Repository off the RevWalk.

On Windows, FS_Win32_Cygwin has been used if a Cygwin Git installation
is present in the PATH. Assuming that the user works with the Cygwin
Git installation may result in unnecessary overhead if he actually
does not.
Applications built on top of jgit may have more knowledge on the
actually used Git client (Cygwin or not) and hence should be able to
configure which FS to use accordingly.
