[GSoC][PATCH v3 0/4] Incremental rewrite of git-submodules

Changes in v3:

* The name of the iterator function for_each_submodule() was changed
  to the for_each_listed_submodule(), as the function fits the naming
  pattern for_each_Y_X(), as here we iterate over group of listed
  submodules (X) which are listed (Y) by the function module_list_compute()
* The name of the call back function type for the above pattern
  for_each_Y_X() is each_X_fn. Hence, this pattern was followed and
  the name of the call back function type for for_each_listed_submodule()
  was changed from submodule_list_func_t to each_submodule_fn.
