[PATCH v4] cache-tree.c: remove implicit dependency on the_repository

["Chinmoy via GitGitGadget" <gitgitgadget@gmail.com>]

From: Chinmoy Chakraborty <chinmoy12c@gmail.com>

This kills the_repository dependency in cache_tree_update()
and prime_cache_tree().

    Replace the_repository with r
    
    There are multiple files that try to reference the repository and
    the_index directly. To follow a more object-oriented convention these
    references should be replaced with r and index and passed through
    functions.

     * Used istate->repo instead of the_repository to prevent making changes
       in callers of the function.
