[PATCH 3/4] run-command: redefine start_command() as a wrapper macro

["Burak Kaan Karaçay" <bkkaracay@gmail.com>]

In the commit introducing 'repo_start_command()', 'start_command()' was
redefined as a wrapper function.

Now, redefine 'start_command()' as a wrapper macro to make 'the_repository'
dependency explicit at the caller's site. To successfully build, expose
'the_repository' dependency at the call sites by defining
'USE_THE_REPOSITORY_VARIABLE' or including 'repository.h' where necessary.
