  refs: split internal and external references
  
  Currently libgit2 shares pointers to its internal reference cache with
  the user. This leads to several problems like invalidation of reference
  pointers when reordering the cache or manipulation of the cache from
  user side.
  
  Give each user its own git_reference instead of leaking the internal
  representation (struct reference).
  
  Add the following new API functions:
  
  	* git_reference_free
  	* git_reference_is_packed
