Implemented algorithm described in "File System Support for Delta Compression" paper, from "Joshua P. MacDonald".

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.

Fix missing objects if they where deltified using ref-delta
|
| | |
| |
| |
| |
| | |
- 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.

* server: add generic server implementation (transport-independent),
both for git-upload-pack and git-receive-pack.
* server: move internal functions to internal/common.
* cli: add git-receive-pack and git-upload-pack implementations.
* format/packfile: add UpdateObjectStorage function, extracted from
Remote.
* transport: implement tranport RPC-like, only with git-upload-pack and
git-receive-pack methods. Client renamed to Transport.
* storer: add storer.Storer interface.
* protocol/packp: add UploadPackResponse constructor with packfile.
* protocol/packp: fix UploadPackResponse encoding, add tests.
* protocol/packp/capability: implement All.

* 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.

* format/packfile: implement delta encoding
- Added all the logic to the encoder to be able to encode ref-delta and offset-delta objects
- Created plumbing.ObjectToPack to handle deltas and standard objects when we are writting them into a packfile
- Added specific encoder delta tests, one standard object and one delta, and one standard object and two deltas
* Requested changes.
