Reuse delta base object cache for packfile decoders
across multiple instances.

* renamed Add to Put
* Get returns a second bool value to indicate if there
was hit or miss.

There was an internal type (i.e. storage/filesystem.idx) to
use as in-memory index for packfiles. This was not convenient
to reuse in the packfile.
This commit creates a new representation (format/packfile.Index)
that can be converted to and from idxfile.Idxfile.
A packfile.Index now contains the functionality that was scattered
on storage/filesystem.idx and packfile.Decoder's internals.
storage/filesystem now reuses packfile.Index instances and this
also results in higher cache hit ratios when resolving deltas.

This has signature and behavior distinct from io.Seeker,
go vet complains about this, so we change it to a different name
to avoid confusion.

To be able to fix #261 we will move again to gopkg.in before v4 stable release.

Because cache package is only intended to be used at internal level, we move it to the plumbing package.

- Deleted invalid logic that returned nil if an ref-delta was not found into the decoder index. This logic was missing objects if it was deltified using ref-deltas.
- Now, to avoid that problem, index is mandatory to decode correctly a packfile of a specific type. Decoder.SetOffsets method now is called into the EncodedObjectIterator to avoid this problem.

* Simple object cache that keeps in memory the last undeltified objects.
When no more objects can be kept into memory, the oldest one is deleted (FIFO).
This speeds up packfile operations preventing redundant seeks and decodes.

* plumbing: rename Object -> EncodedObject.
* plumbing/storer: rename ObjectStorer -> EncodedObjectStorer.
* move difftree to plumbing/difftree.
* move diff -> utils/diff
* make Object/Tag/Blob/Tree/Commit/File depend on storer.
* Object and its implementations now depend only on
storer.EncodedObjectStorer, not git.Repository.
* Tests are decoupled accordingly.
* move Object/Commit/File/Tag/Tree to plumbing/object.
* move Object/Commit/File/Tag/Tree to plumbing/object.
* move checkClose to utils/ioutil.
* move RevListObjects to plumbing/revlist.Objects.
* move DiffTree to plumbing/difftree package.
* rename files with plural nouns to singular
* plumbing/object: add GetBlob/GetCommit/GetTag/GetTree.
