[GSoC] [PATCH 0/3] submodule add: partial conversion to C

This is based on a previous series I sent[1] which got a bunch of reviews at the
time from Christian, Danh, Junio, Rafael and Eric.

This series only includes changes pertaining to the 'add-clone' subcommand, and
the patches have remained the same as before, except for the inclusion of a
custom die routine 'submodule_die()' that makes all the die()'s behave identical
to the shell version of 'die'. I am particularly interested in opinions about
this change.

A test has been added to ensure no regressions are introduced during the
conversion.

I am holding on to a full conversion of submodule add[2], and sending only a
portion of it, so that the parts that already have been seen before on the list
and refined can be merged. I then plan to send the rest of the patches that
build on top of this series.
