  repository: Change ownership semantics
  
  The ownership semantics have been changed all over the library to be
  consistent. There are no more "borrowed" or duplicated references.
  
  Main changes:
  
  	- `git_repository_open2` and `3` have been dropped.
  
  	- Added setters and getters to hotswap all the repository owned
  	objects:
  
  		`git_repository_index`
  		`git_repository_set_index`
  		`git_repository_odb`
  		`git_repository_set_odb`
  		`git_repository_config`
  		`git_repository_set_config`
  		`git_repository_workdir`
  		`git_repository_set_workdir`
  
  	Now working directories/index files/ODBs and so on can be
  	hot-swapped after creating a repository and between operations.
  
  	- All these objects now have proper ownership semantics with
  	refcounting: they all require freeing after they are no longer
  	needed (the repository always keeps its internal reference).
  
  	- Repository open and initialization has been updated to keep in
  	mind the configuration files. Bare repositories are now always
  	detected, and a default config file is created on init.
  
  	- All the tests affected by these changes have been dropped from the
  	old test suite and ported to the new one.
