add: modify add_files_to_cache() to avoid globals
The function add_files_to_cache() is used by all three of builtin/{add,
checkout, commit}.c. That suggests this is common library code, and
should be moved somewhere else, like read-cache.c. However, the
function and its helpers made use of two global variables that made
straight code movement difficult:
* the_index
* include_sparse
The latter was perhaps more problematic since it was only accessible in
builtin/add.c but was still affecting builtin/checkout.c and
builtin/commit.c without this fact being very clear from the code. I'm
not sure if the other two callers would want to add a `--sparse` flag
similar to add.c to get non-default behavior, but exposing this
dependence will help if we ever decide we do want to add such a flag.
Modify add_files_to_cache() and its helpers to accept the necessary
arguments instead of relying on globals.
