[PATCH V2 0/3] wt-status: reduce reliance on global state

In wt-status.c code still relies on some global variables, including the_repository and the_hash_algo, even in cases where a repository instance is already available via struct wt_status or struct worktree.

In patch 1/3, replace direct uses of the_repository with repository instances already available in local structs.

In patch 2/3, update function parameters and calls to pass struct repository or struct wt_status explicitly where no local repository access was available.

In patch 3/3, replace remaining uses of the global the_hash_algo with the hash algorithm stored in the respective repository instance.

These changes remove all direct uses of the_repository and the_hash_algo from wt-status.c and reduce its dependence on global state.

The 'USE_THE_REPOSITORY_VARIABLE' macro cannot yet be removed, since these patches only eliminate direct uses of the_repository and the_hash_algo, while other global variables are still referenced.

In particular wt-status.c still relies on the following globals,

* core_apply_sparse_checkout, this is already being addressed in an
ongoing patch series [1].

* comment_line_str and DEFAULT_ABBREV, these both still are used in
wt-status.c but they dont have any equivalent local instances.

  wt-status: use hash_algo from local repository instead of global
    the_hash_algo
