[PATCH v1 0/5] Incremental rewrite of git-submodules

[Prathamesh Chavan <pc44800@gmail.com>]

Following series of patches focuses on porting submodule subcommand
git-foreach from shell to C.
An initial attempt for porting was introduced about 9 months back,
and since then then patches have undergone many changes. Some of the 
notable discussion thread which I would like to point out is: [1] 
The previous version of this patch series which was floated is
available at: [2].

The following changes were made to that:
* As it was observed in other submodule subcommand's ported function
  that the number of params increased a lot, the variables quiet and 
  recursive, were replaced in the cb_foreach struct with a single
  unsigned integer variable called flags.

* To accomodate the possiblity of a direct call to the functions
  runcommand_in_submodule(), callback function
  runcommand_in_submodule_cb() was introduced.
