  I broke your bindings
  
  Hey. Apologies in advance -- I broke your bindings.
  
  This is a major commit that includes a long-overdue redesign of the
  whole object-database structure. This is expected to be the last major
  external API redesign of the library until the first non-alpha release.
  
  Please get your bindings up to date with these changes. They will be
  included in the next minor release. Sorry again!
  
  Major features include:
  
  	- Real caching and refcounting on parsed objects
  	- Real caching and refcounting on objects read from the ODB
  	- Streaming writes & reads from the ODB
  	- Single-method writes for all object types
  	- The external API is now partially thread-safe
  
  The speed increases are significant in all aspects, specially when
  reading an object several times from the ODB (revwalking) and when
  writing big objects to the ODB.
  
  Here's a full changelog for the external API:
  
  blob.h
  ------
  
  	- Remove `git_blob_new`
  	- Remove `git_blob_set_rawcontent`
  	- Remove `git_blob_set_rawcontent_fromfile`
  	- Rename `git_blob_writefile` -> `git_blob_create_fromfile`
  	- Change `git_blob_create_fromfile`:
  		The `path` argument is now relative to the repository's working dir
  	- Add `git_blob_create_frombuffer`
  
  commit.h
  --------
  
  	- Remove `git_commit_new`
  	- Remove `git_commit_add_parent`
  	- Remove `git_commit_set_message`
  	- Remove `git_commit_set_committer`
  	- Remove `git_commit_set_author`
  	- Remove `git_commit_set_tree`
  
  	- Add `git_commit_create`
  	- Add `git_commit_create_v`
  	- Add `git_commit_create_o`
  	- Add `git_commit_create_ov`
  
  tag.h
  -----
  
  	- Remove `git_tag_new`
  	- Remove `git_tag_set_target`
  	- Remove `git_tag_set_name`
  	- Remove `git_tag_set_tagger`
  	- Remove `git_tag_set_message`
  
  	- Add `git_tag_create`
  	- Add `git_tag_create_o`
  
  tree.h
  ------
  
  	- Change `git_tree_entry_2object`:
  		New signature is `(git_object **object_out, git_repository *repo, git_tree_entry *entry)`
  
  	- Remove `git_tree_new`
  	- Remove `git_tree_add_entry`
  	- Remove `git_tree_remove_entry_byindex`
  	- Remove `git_tree_remove_entry_byname`
  	- Remove `git_tree_clearentries`
  	- Remove `git_tree_entry_set_id`
  	- Remove `git_tree_entry_set_name`
  	- Remove `git_tree_entry_set_attributes`
  
  object.h
  ------------
  
  	- Remove `git_object_new
  	- Remove `git_object_write`
  
  	- Change `git_object_close`:
  		This method is now *mandatory*. Not closing an object causes a
  		memory leak.
  
  odb.h
  -----
  
  	- Remove type `git_rawobj`
  	- Remove `git_rawobj_close`
  	- Rename `git_rawobj_hash` -> `git_odb_hash`
  	- Change `git_odb_hash`:
  		New signature is `(git_oid *id, const void *data, size_t len, git_otype type)`
  
  	- Add type `git_odb_object`
  	- Add `git_odb_object_close`
  
  	- Change `git_odb_read`:
  		New signature is `(git_odb_object **out, git_odb *db, const git_oid *id)`
  	- Change `git_odb_read_header`:
  		New signature is `(size_t *len_p, git_otype *type_p, git_odb *db, const git_oid *id)`
  	- Remove `git_odb_write`
  	- Add `git_odb_open_wstream`
  	- Add `git_odb_open_rstream`
  
  odb_backend.h
  -------------
  
  	- Change type `git_odb_backend`:
  		New internal signatures are as follows
  
  			int (* read)(void **, size_t *, git_otype *, struct git_odb_backend *, const git_oid *)
  			int (* read_header)(size_t *, git_otype *, struct git_odb_backend *, const git_oid *)
  			int (* writestream)(struct git_odb_stream **, struct git_odb_backend *, size_t, git_otype)
  			int (* readstream)( struct git_odb_stream **, struct git_odb_backend *, const git_oid *)
  
  	- Add type `git_odb_stream`
  	- Add enum `git_odb_streammode`
