[JGIT PATCH 06/21] Allow PackIndexWriter to use any subclass of PackedObjectInfo

["Shawn O. Pearce" <spearce@spearce.org>]

Some users of PackIndexWriter may have extended PackedObjectInfo
to store additional implementation specific details, but wish to
pass off their own subclass instances to avoid allocating even
more memory.
