[GSoC][PATCH v3 00/13] rebase -i: rewrite some parts in C

[Alban Gruin <alban.gruin@gmail.com>]

This patch series rewrites some parts of interactive rebase from shell
to C:

 - append_todo_help(). The C version covers a bit more than the shell
   version.

 - The edit-todo functionnality.

 - The reflog operations.

 - complete_action().

 - init_revisions_and_shortrevisions().

This patch series is based on master (as of 2018-07-10).

Changes since v2:

 - Lowercasing error messages.

 - Removing a comment from run_command_silent_on_success().

 - Using the `else` keyword to call run_command_silent_on_success() or
   run_command() in run_git_commit() and run_git_checkout().

 - Dropping the `verbose` parameter in run_git_checkout(),
   prepare_branch_to_be_rebased(), and checkout_onto(), as the
   replay_opts structure already has a `verbose` field.

 - Rewriting complete_action() and init_revisions_and_shortrevisions().
