[PATCH v2 0/6] Kill the_repository in tree-walk.c

v2 fixes t7814 flakiness. The problem is git-grep can operate on multiple repos and I read objects from the wrong repo (supermodule) instead of the submodule one.

There are still the_repository hidden in git-grep code paths, and the hack of asborbing submodule's object db to the_repo's in order to make it work. And I can't quite understand how t7814 sometimes passed.

I'll revisit this after this series is done and will try to get rid of add_to_alternates_memory() in git-grep.

Nguyễn Thái Ngọc Duy (6):
  sha1-file.c: remove the_repo from read_object_with_reference()
  tree-walk.c: remove the_repo from fill_tree_descriptor()
  tree-walk.c: remove the_repo from get_tree_entry()
  tree-walk.c: remove the_repo from get_tree_entry_follow_symlinks()
  match-trees.c: remove the_repo from shift_tree*()
  Use the right 'struct repository' instead of the_repository
