Allow use of ArchiveCommand without depending on the jgit command-line
tools.
To avoid complicating the process of installing and upgrading JGit,
this does not add a dependency by the org.eclipse.jgit bundle on
commons-compress. Instead, the caller is responsible for registering
any formats they want to use by calling ArchiveCommand.registerFormat.
This patch puts functionality that requires an archiver into a
separate org.eclipse.jgit.archive bundle for people who want it. One
can use it by calling ArchiveCommand.registerFormat directly to
register its formats or by relying on OSGi class loading to load
org.eclipse.jgit.archive.FormatActivator, which takes care of
registration automatically.
Once the appropriate formats are registered, you can make a tar or zip
from a git tree object as follows:
ArchiveCommand cmd = git.archive();
try {
cmd.setTree(tree).setFormat(fmt).setOutputStream(out).call();
} finally {
cmd.release();
}

Provide static registerFormat and unregisterFormat methods to allow
formats to register themselves without the ArchiveCommand code being
aware of them.
Register the basic "zip" and "tar" support at bundle activation time
(and deregister them when unloading the bundle). For anyone using
this code as an OSGi plugin it should continue to just work.
The jgit program does not load org.eclipse.jgit.pgm as an OSGi bundle,
so let the Archive command register the formats it uses explicitly
with registerFormat.

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.

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.

This experiment proved to be not very useful. I had originally
planned to use this on top of Google Bigtable, Apache HBase or
Apache Cassandra. Unfortunately the schema is very complex and
does not perform well. The storage.dfs package has much better
performance and has been in production at Google for many months
now, proving it is a viable storage backend for Git.
As there are no users of the storage.dht schema, either at Google or
any other company, nor any valid open source implementations of the
storage system, drop the entire package and API from the JGit project.
There is no point in trying to maintain code that is simply not used.

The standard Google distribution of Protocol Buffers in Java is better
maintained than TinyProtobuf, and should be faster for most uses. It
does use slightly more memory due to many of our key types being
stored as strings in protobuf messages, but this is probably worth the
small hit to memory in exchange for better maintained code that is
easier to reuse in other applications.
Exposing all of our data members to the underlying implementation
makes it easier to develop reporting and data mining tools, or to
expand out a nested structure like RefData into a flat format in a SQL
database table.
Since the C++ `protoc` tool is necessary to convert the protobuf
script into Java code, the generated files are committed as part of
the source repository to make it easier for developers who do not have
this tool installed to still build the overall JGit package and make
use of it. Reviewers will need to be careful to ensure that any edits
made to a *.proto file come in a commit that also updates the
generated code to match.

jgit.storage.dht is a storage provider implementation for JGit that
permits storing the Git repository in a distributed hashtable, NoSQL
system, or other database. The actual underlying storage system is
undefined, and can be plugged in by implementing 7 small interfaces:
* Database
* RepositoryIndexTable
* RepositoryTable
* RefTable
* ChunkTable
* ObjectIndexTable
* WriteBuffer
The storage provider interface tries to assume very little about the
underlying storage system, and requires only three key features:
* key -> value lookup (a hashtable is suitable)
* atomic updates on single rows
* asynchronous operations (Java's ExecutorService is easy to use)
Most NoSQL database products offer all 3 of these features in their
clients, and so does any decent network based cache system like the
open source memcache product. Relying only on key equality for data
retrevial makes it simple for the storage engine to distribute across
multiple machines. Traditional SQL systems could also be used with a
JDBC based spi implementation.
Before submitting this change I have implemented six storage systems
for the spi layer:
* Apache HBase[1]
* Apache Cassandra[2]
* Google Bigtable[3]
* an in-memory implementation for unit testing
* a JDBC implementation for SQL
* a generic cache provider that can ride on top of memcache
All six systems came in with an spi layer around 1000 lines of code to
implement the above 7 interfaces. This is a huge reduction in size
compared to prior attempts to implement a new JGit storage layer. As
this package shows, a complete JGit storage implementation is more
than 17,000 lines of fairly complex code.
A simple cache is provided in storage.dht.spi.cache. Implementers can
use CacheDatabase to wrap any other type of Database and perform fast
reads against a network based cache service, such as the open source
memcached[4]. An implementation of CacheService must be provided to
glue this spi onto the network cache.

Tycho isn't production ready for projects like JGit to be using as
their primary build driver. Some problems we ran into with Tycho
0.6.0 that are preventing us from using it are:
* Tycho can't run offline
The P2 artifact resolver cannot perform its work offline. If the
build system has no network connection, it cannot compile a
project through Tycho. This is insane for a distributed version
control system where developers are used to being offline during
development and local testing.
* Magic state in ~/.m2/repository/.meta/p2-metadata.properties
Earlier iterations of this patch tried to use a hybrid build,
where Tycho was only used for the Eclipse specific feature and P2
update site, and maven-bundle-plugin was used for the other code.
This build seemed to work, but only due to magic Tycho specific
state held in my local home directory. This means builds are not
consistently repeatable across systems, and lead me to believe
I had a valid build, when in fact I did not.
* Manifest-first build produces incomplete POMs
The POM created by the manifest-first build format does not
contain the dependency chain, leading a downstream consumer to
not import the runtime dependencies necessary to execute the
bundle it has imported. In JGit's case, this means JSch isn't
included in our dependency chain.
* Manifest-first build produces POMs unreadable by Maven 2.x
JGit has existing application consumers who are relying on
Maven 2.x builds. Forcing them to step up to an alpha release
of Maven 3 is simply unacceptable.
* OSGi bundle export data management is tedious
Editing each of our pom.xml files to mark a new release is
difficult enough as it is. Editing every MANIFEST.MF file to
list our exported packages and their current version number is
something a machine should do, not a human. Yet the Tycho OSGi
way unfortunately demands that a human do this work.
* OSGi bundle import data management is tedious
There isn't a way in the MANIFEST.MF file format to reuse the
same version tags across all of our imports, but we want to have
a consistent view of our dependencies when we compile JGit.
After wasting more than 2 full days trying to get Tycho to work,
I've decided its a lost cause right now. We need to be chasing down
bugs and critical features, not trying to bridge the gap between
the stable Maven repository format and the undocumented P2 format
used only by Eclipse.
So, switch the build to use Apache Felix's maven-bundle-plugin.
This is the same plugin Jetty uses to produce their OSGi bundle
manifests, and is the same plugin used by the Apache Felix project,
which is an open-source OSGi runtime. It has a reasonable number
of folks using it for production builds, and is running on top of
the stable Maven 2.x code base.
With this switch we get automatically generated MANIFEST.MF files
based on reasonably sane default rules, which reduces the amount
of things we have to maintain by hand. When necessary, we can add
a few lines of XML to our POMs to tweak the output.
Our build artifacts are still fully compatible with Maven 2.x, so
any downstream consumers are still able to use our build products,
without stepping up to Maven 3.x. Our artifacts are also valid as
OSGi bundles, provided they are organized on disk into a repository
that the runtime can read.
With maven-bundle-plugin the build runs offline, as much as Maven
2.x is able to run offline anyway, so we're able to return to a
distributed development environment again.
By generating MANIFEST.MF at the top level of each project (and
therefore outside of the target directory), we're still compatible
with Eclipse's PDE tooling. Our projects can be imported as standard
Maven projects using the m2eclipse plugin, but the PDE will think
they are vaild plugins and make them available for plugin builds,
or while debugging another workbench.
This change also completely removes Tycho from the build.
Unfortunately, Tycho 0.6.0's pom-first dependency resolver is broken
when resolving a pom-first plugin bundle through a manifest-first
feature package, so bundle org.eclipse.jgit can't be resolved,
even though it might actually exist in the local Maven repository.
Rather than fight with Tycho any further, I'm just declaring it
plugina-non-grata and ripping it out of the build.
Since there are very few tools to build a P2 format repository, and
no documentation on how to create one without running the Eclipse
UI manually by poking buttons, I'm declaring that we are not going
to produce a P2 update site from our automated builds.

To avoid too much refactoring of the current code we reuse the

The command line wrapper jgit.sh no longer works in the uncompiled
