Fix junit tests under windows when the platform is explicitly changed
SystemReader used a chached ObjectChecker which was instantiated only
once. But in case of unit tests where we can change the platform
dynamically (e.g. MockSystemReader.setWindows()) this is wrong and
caused DirCacheCheckoutMaliciousPathTest.
testMaliciousAbsoluteCurDrivePathWindowsOnUnix() to fail. This change
allows
user of SystemReader to force the creation of a new ObjectChecker.
MockSystemReader.setWindows() and .setUnix() make use of this feature.

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.

Deprecate TemporaryBuffer.LocalFile without parent directory
Encourage callers to explicitly name a directory to hold any
overflow data. Call sites have more information about what is
going into the buffer and how it should be protected at the
filesystem level than just throwing content to the system wide
temporary directory.
Callers that still really don't care (or need to care) can pass
null for the File argument to have the system directory used.

Adds GSSManager factory class, to be used for SPNEGO HTTP authentication
Adds a factory class for GSSManager. GSSManager is already a factory class but
it doesn't work well with SPNEGO HTTP authentication unless the
javax.security.auth.useSubjectCredsOnly system property is set to false.
On Sun JDK, Sun GSSManagerImpl can be configured directly for SPNEGO auth
(without setting any system property). For a better experience, the class
availability is detected by reflection and used instead.
Detection is only done once, and fallbacks to org.ietf.jgss.GSSManager.

Cleanup catch Exception when making Java7FSFactory
Catching Exception and rethrowing as Error when the Java7 factory was
not available threw an unexpected error to the caller, but then
confused things by still setting the factory to the default Java
5 version. A second call to FS.detect(Boolean) would succeed.
Do not throw to the caller. Instead always default to the Java5
factory if the Java7 one is not loading.

Previously all HTTP communication was done with the help of
java.net.HttpUrlConnection. In order to make JGit usable in environments
where the direct usage of such connections is not allowed but where the
environment provides other means to get network connections an
abstraction for connections is introduced. The idea is that new
implementations of this interface will be introduced which will not use
java.net.HttpUrlConnection but use e.g.
org.apache.client.http.HttpClient to provide network connections.
One example: certain cloud infrastructures don't allow that components
in the cloud communicate directly with HttpUrlConnection. Instead they
provide services where a component can ask for a connection (given a
symbolic name for the destination) and where the infrastructure returns
a preconfigured org.apache.http.client.HttpClient. In order to allow
JGit to be running in such environments we need the abstraction
introduced in this commit.

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.

The most important difference is that in Java7 we have symbolic links
and for most operations in the work tree we want to operate on the link
itself rather than the link target, which the old File methods generally
do.
We also add support for the hidden attribute, which only makes sense
on Windows and exists, just since there are claims that Files.exists
is faster the File.exists.
A new bundle is only activated when run with a Java7 execution
environment. It is implemented as a fragment.
Tycho currently has no way to conditionally include optional features
based on the java version used to run the build, this means with this
change the jgit packaging build always needs to be run using java 7.

Unlike the OS or Java rename this method will (on *nix) try (on Windows)
replace the target with the source provided the target does not exist,
the target does exist and is a file, or if it is a directory which only
contains directories. In the latter case the directory hierarchy will be
deleted.
If the initial rename fails and the target is an existing file the the
target file will be deleted first and then the rename is retried.

Only on Windows the rename operation which renames temporary Packfiles
(and index-files and bitmap-files) sometime fails. This happens only
when renaming a temporary Packfile to a Packfile which already exists.
Such situations occur if you run GC twice on a repo without modifying
the repo inbetween.
In such situations there was bug in GC which led to a corrupted repo
whithout any packfiles anymore. This commit fixes the problem by
introducing a utility method which renames a file and throws an
IOException if it fails. This method also takes care to repeat a
failing rename if our FS class has found out we are running on a
platform with a unreliable File.renameTo() method.
I am searching for a better solution because even with this utility
method in hand a GC on a already GC'ed repo will fail on Windows. But
at least with this fix we will not produce corrupted repos anymore.

A pack bitmap index is an additional index of compressed
bitmaps of the object graph. Furthermore, a logical API of the index
functionality is included, as it is expected to be used by the
PackWriter.
Compressed bitmaps are created using the javaewah library, which is a
word-aligned compressed variant of the Java bitset class based on
run-length encoding. The library only works with positive integer
values. Thus, the maximum number of ObjectIds in a pack file that
this index can currently support is limited to Integer.MAX_VALUE.
Every ObjectId is given an integer mapping. The integer is the
position of the ObjectId in the complete ObjectId list, sorted
by offset, for the pack file. That integer is what the bitmaps
use to reference the ObjectId. Currently, the new index format can
only be used with pack files that contain a complete closure of the
object graph e.g. the result of a garbage collection.
The index file includes four bitmaps for the Git object types i.e.
commits, trees, blobs, and tags. In addition, a collection of
bitmaps keyed by an ObjectId is also included. The bitmap for each entry
in the collection represents the full closure of ObjectIds reachable
from the keyed ObjectId (including the keyed ObjectId itself). The
bitmaps are further compressed by XORing the current bitmaps against
prior bitmaps in the index, and selecting the smallest representation.
The XOR'd bitmap and offset from the current entry to the position
of the bitmap to XOR against is the actual representation of the entry
in the index file. Each entry contains one byte, which is currently
used to note whether the bitmap should be blindly reused.
