Merge branch 'ss/submodule-summary-in-c'

Yet another subcommand of "git submodule" is getting rewritten in C.

* ss/submodule-summary-in-c:
  submodule: port submodule subcommand 'summary' from shell to C
  t7421: introduce a test script for verifying 'summary' output
  submodule: rename helper functions to avoid ambiguity
  submodule: remove extra line feeds between callback struct and macro

This test script tries to verify the sanity of summary subcommand of git submodule.
'
# NOTE: This test script uses 'git add' instead of 'git submodule add' to add
# submodules to the superproject. Some submodule subcommands such as init and
# deinit might not work as expected in this script. t7421 does not have this
# caveat.
#
# NEEDSWORK: This test script is old fashioned and may need a big cleanup due to
# various reasons, one of them being that there are lots of commands taking place
# outside of 'test_expect_success' block, which is no longer in good-style.

test_description='Summary support for submodules, adding them using git submodule add
This test script tries to verify the sanity of summary subcommand of git submodule
while making sure to add submodules using `git submodule add` instead of
`git add` as done in t7401.
