PackBitmapIndexBuilder.StoredEntry: add getter for objectId
If you only have access to the PackBitmapIndexBuilder there is no way to
get the ObjectId from a StoredEntry instance without also having access
to a reverse pack index. The StoredEntry can provide the idxPosition,
but the PackBitmapIndexBuilder's getObject method requires a
ridxPosition in order to find an ObjectId.
Providing an ObjectId from the StoredEntry gives this information
directly and also allows a caller to get the ridxPosition if desired by
calling PackBitmapIndexBuilder.findPosition(objectId) without needing
an index object.
This closes the operations of the PackBitmapIndexBuilder such that any
method can be called by using information provided by the other methods.

ShutdownHook: run on bundle deactivation if in OSGi
Running as a JVM shutdown hook is far too late in an OSGi framework; by
the time the JVM shuts down, the OSGi framework will normally already
have deactivated and unloaded bundles, and thus the JGit cleanup code
may try to work with unloaded classes for which there will be no
classloader anymore.
When JGit is used in an OSGi framework, the cleanups must run on bundle
deactivation, not on JVM shut down.
Add a declarative OSGi service CleanupService. This is a normal Java
class that has no dependencies on any OSGi bundle or interface, but
that is declared in the MANIFEST.MF and in an OSGi Service XML as an
OSGi immediate component. Set the bundle activation policy to "lazy".
(A declarative service is used instead of a bundle activator because the
latter would need to implement the OSGi interface BundleActivator, but
JGit should not have dependencies on OSGi.)
When JGit runs in an OSGi framework, the framework will create an
instance of CleanupService through the no-args constructor when (and
before) the first class from this bundle is loaded. This instance thus
knows that it is operating in OSGi, and will run the ShutdownHook when
the bundle is deactivated: bundle deactivation will deactivate the
CleanupService instance.
When JGit does not run in an OSGi framework, the OSGi service
declaration will be ignored, and there will be no already existing
CleanupService instance. We create one lazily, which thus knows that
it is not operating in OSGi, and which will use a JVM shutdown hook to
run the ShutdownHook.

'core.trustLooseRefStat' that will optionally refresh file attributes of

* always: Trust loose ref file attributes (default)
* after_open: Similar to 'always', but refresh the file attributes of
the loose ref and its parent directories before trusting
it
The default is set to always trust the file attributes as after_open is

cache the directories that were refreshed to avoid duplicate work and

SnapshottingRefDirectory: Invalidate snapshot after locking ref for

thread may create an update that is based on the old cached/snapshotted
packed-refs content. That update could effectively perform a forced
update unintentionally because it is unaware of the new content.
This seems particularly likely to happen in a scenario where a loose
ref was just packed. If the ref was loose, our thread would see the
current ref value (because we don't snapshot loose refs and always read
them from disk), but since there is no loose ref, we expect to find the
current value in packed-refs. However, (before this change) we rely
on our snapshot of packed-refs which does not contain the updated ref
value.
Invalidating the cache after the loose ref is locked ensures that the
ref value does not change again before we read it to perform the update.
