Subject: [PATCH v2 8/8] trailer: retire trailer_info_get() from API

From: "Linus Arver via GitGitGadget" <[email-masked]>
Date: Fri, 19 Apr 2024 05:22:33 +0000

From: Linus Arver <[email-masked]>

Make trailer_info_get() "static" to be file-scoped to trailer.c, because
no one outside of trailer.c uses it. Remove its declaration from
<trailer.h>.

We have to also reposition it to be above parse_trailers(), which
depends on it.
