On the fsfs-ucsnorm branch: Another key vs. name clarification.

* subversion/libsvn_fs_fs/temp_serializer.h (svn_fs_fs__extract_dir_entry):
   Document the semantics of the lookup key. Note that the only caller
   of this function already conforms to the restrictions.
* subversion/libsvn_fs_fs/temp_serializer.c
  (svn_fs_fs__extract_dir_entry): Rename the local variable 'name' to 'key'.
  (svn_fs_fs__replace_dir_entry): Fix comment to mention 'key'.
