  Redesigned the walking/object lookup interface
  
  The old 'git_revpool' object has been removed and
  split into two distinct objects with separate
  functionality, in order to have separate methods for
  object management and object walking.
  
  *	A new object 'git_repository' does the high-level
  	management of a repository's objects (commits, trees,
  	tags, etc) on top of a 'git_odb'.
  
  	Eventually, it will also manage other repository
  	attributes (e.g. tag resolution, references, etc).
  
  	See: src/git/repository.h
  
  *	A new external method
  		'git_repository_lookup(repo, oid, type)'
  	has been added to the 'git_repository' API.
  
  	All object lookups (git_XXX_lookup()) are now
  	wrappers to this method, and duplicated code
  	has been removed. The method does automatic type
  	checking and returns a generic 'git_revpool_object'
  	that can be cast to any specific object.
  
  	See: src/git/repository.h
  
  *	The external methods for object parsing of repository
  	objects (git_XXX_parse()) have been removed.
  
  	Loading objects from the repository is now managed
  	through the 'lookup' functions. These objects are
  	loaded with minimal information, and the relevant
  	parsing is done automatically when the user requests
  	any of the parsed attributes through accessor methods.
  
  	An attribute has been added to 'git_repository' in
  	order to force the parsing of all the repository objects
  	immediately after lookup.
  
  	See: src/git/commit.h
  	See: src/git/tag.h
  	See: src/git/tree.h
  
  *	The previous walking functionality of the revpool
  	is now found in 'git_revwalk', which does the actual
  	revision walking on a repository; the attributes
  	when walking through commits in a database have been
  	decoupled from the actual commit objects.
  	This increases performance when accessing commits
  	during the walk and allows to have several
  	'git_revwalk' instances working at the same time on
  	top of the same repository, without having to load
  	commits in memory several times.
  
  	See: src/git/revwalk.h
  
  *	The old 'git_revpool_table' has been renamed to
  	'git_hashtable' and now works as a generic hashtable
  	with support for any kind of object and custom hash
  	functions.
  
  	See: src/hashtable.h
  
  *	All the relevant unit tests have been updated, renamed
  	and grouped accordingly.
