Re: [PATCH v3 07/10] trailer: prepare to move parse_trailers_from_command_line_args() to builtin

"Linus Arver via GitGitGadget" [off-list ref] writes:

Rename add_arg_item() to trailer_add_arg_item() because it will have to
be exposed as an API function in the next patch. Rename
new_trailers_clear() to free_new_trailers() because it will be promoted
into an API function; the API already has free_trailers(), so using the
"free_*" naming style will keep it consistent. Also rename "conf_info"
to "trailer_conf" for readability, dropping the low-value "_info" suffix
as we did earlier in this series for "trailer_info" to "trailer_block".

Makes sense.

Thanks.
