[calls/wip/compiler-warnings: 5/12] Fix missing-declarations warnings all over the codebase

[Evangelos Ribeiro Tzaras <devrtz src gnome org>]

commit 1a4814570deac96e9b8432a608d3490b6ebde054
Author: Evangelos Ribeiro Tzaras <evangelos tzaras puri sm>
Date:   Wed Jun 2 19:42:25 2021 +0200

    Fix missing-declarations warnings all over the codebase
    
    As caught by compiling with `-Wmissing-declarations`
    by either making functions static, or declaring them in the header.
