Set "potentialNullReference" to "error" level and fixed all issues
There should be no functional change, the logic updated only to make
code simple so that compiler can understand what is going for. Removed
all @SuppressWarnings("null") annotations since they cannot be used if
"org.eclipse.jdt.core.compiler.problem.potentialNullReference" option is
set to the "error" level.

When DirCacheTree.contains() is called and 'aOff' is greater than 'aLen'
an ArrayIndexOutOfBoundsException was thrown. This fix makes
DirCacheTree.contains() more robust and allows parsing such index files
without throwing AIOOB.
I couldn't create a test case leading to this situation but I have seen
such situations while inspecting Bug: 465393. It seems that such
situations are created on Windows when there are invalid pathes in the
index. There may be a not yet known bug leading to such situations in
combination with invalid pathes.

In case the index contains wrong tree extensions don't throw a
ArrayIndexOutOfBounds exception but revalidate the tree extension.
It happened that the git index written by Git for Windows contained valid
(means entryCount>0) tree extensions for pathes which are not existing
in the index. Native git handles this inconsistency silently but JGit
was crashing with a ArrayIndexOutOfBounds exception. Teach JGit to
better recognize such cases and revalidate such extensions.
It's hard to write a test because JGit doesn't write such extensions. It
only reads, validates and makes use of them. But the bug tells how to
create such situations.

DirCache: Replace isValidPath with DirCacheCheckout.checkValidPath
isValidPath is an older simple form of the validation performed by
checkValidPath. Use the latter as it more consistently matches
git-core's validation rules.
By running the same validation as fsck, callers creating an entry
for the DirCache are more likely to learn early they are trying
to build trees that will fail fsck.

Move checkPath from DirCacheCheckout to ObjectChecker
The bulk of the "is this sane" logic is inside of ObjectChecker. The
only caller for the version in DirCacheCheckout is an obtuse usage for
the static isValidRefName() method in Repository.
Deprecate the weird single use method in DirCacheCheckout and move all
code for checking a sequence of path components into ObjectChecker,
where it makes sense alongside the existing code that checks a single
component at a time.
Reuse a single ObjectChecker for the local platform, to avoid looking
up the system properties on each path string considered.

Cleanup double stat update of symlinks in DirCacheCheckout
When writing a symlink the stat data should only be written once
into the DirCacheEntry, based on the symlink itself and not the
possibly resolved destination observed by java.io.File.
Refactor the code to handle symlinks and early return. This
removes the risk the blob stat info update is used against a
newly checked out symlink.
Hoist the file length stat update immediately after writing
the file, before a rename. This eliminates any race caused by another
process updating the file length after the rename and having it to
fall into the racily clean path.

Increase the in-memory buffer for the TREE extension to 5 MiB, and
overflow to $GIT_DIR instead of /tmp. Using a larger buffer reduces
the chances a repository will overflow and need to spool the extension
to disk. Using $GIT_DIR allows the TREE extension contents to have
the same file system protections as the final $GIT_DIR/index.
Wrap the entire thing in a try/finally to ensure the temp file is
deleted from disk after the block has finished using it. To avoid
dangling NFS files, LocalFile.destroy() does close the local file
before deleting it.

Make sure checkout doesn't report conflicts on ignored paths
In a situation where a certain path was ignored but a working tree file
with this path existed jgit didn't allow to checkout a branch which
didn't ignore this path but contained different content. JGit considered
this to be a checkout conflict to prevent overwriting the file in the
working tree and raised an error. This commit fixes this by ensuring
that ignored dirty working tree files don't lead to a checkout conflict.

Don't raise checkout conflict for file missing in working tree
During a checkout we want to prevent to overwrite unsaved local file
content. Jgit was therefore checking whether the file to overwrite is
dirty or missing and would raise a conflict if this was the case. That
was wrong. It should only check if the file is dirty. It's ok to
"overwrite" a missing/non-existing file.

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.

Fix handling of file/folder conflicts during a checkout
JGit was not handling certain file/folder conflicts during a checkout
correctly. This was reported by Axel Richard in
http://dev.eclipse.org/mhonarc/lists/jgit-dev/msg02358.html.
This commit fixes this problem.
Still JGit behaves intentionally different than native git.
If HEAD contains a tree, and workingtree, Index and Merge contain a file
with same content ... then JGit allows a conflict free checkout of
Merge. Native git always complains that it doesn't want to overwrite
local changes. But there is no need to update the working tree because
Index and Merge are already equal.
A shell script which shows how native git behaves can be found here.

ResetCommand: Allow reset on unborn branch when ref not specified
In C Git 1.8.2, "git reset" now also works on an unborn branch (no HEAD

reset to an empty tree.
This can be useful for callers because "unborn branch" no longer has to
be special-cased to "git rm --cached".
