* plumbing: add DeltaObject interface for EncodedObjects that
are deltas and hold additional information about them, such
as the hash of the base object.
* plumbing/storer: add DeltaObjectStorer interface for object
storers that can return DeltaObject. Note that calls to
EncodedObject will never return instances of DeltaObject.
That requires explicit calls to DeltaObject.
* storage/filesystem: implement DeltaObjectStorer interface.
* plumbing/packfile: packfile encoder now supports reusing
deltas that are already computed (e.g. from an existing
packfile) if the storage implements DeltaObjectStorer.
Reusing deltas boosts performance of packfile generation
(e.g. on push).

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

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 code crashes if the shallow file doesn't exist.

filesystem.Storage was initializing the gitdir (creating objects
and refs) on NewStorage. But this should be done only on init and
clone operations, not on open.
Now there is a new interface storer.Initializer that storers can
implement if they need any initialization step before init or clone.
filesystem.Storage is one of such implementations.
git.Init and git.Clone now call to the storer Init() method if it
does implement it. Otherwise, it just ignores initialization.

fixes #327

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

- 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.

* Extract billy
Billy is a new library directly extracted from go-git. It abstract
several storages systems in a filesystem interface.
More in github.com/src-d/billy
* Fix grouping in imports block
* Update billy to v1
* Re-remove fs_implementation example

* 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.

* plumbing: move plumbing/client package to plumbing/transport.
* transport: create Client interface.
* A Client can instantiate any client transport service.
* InstallProtocol installs a Client for a given protocol,
instead of just a UploadPackService.
* A Client can open a session for fetch-pack or send-pack
for a specific Endpoint.
* Adapt ssh and http clients to the new client interface.
* updated doc
