tests: Add and include headers with function prototypes

Part 2 of fixing -Wmissing-prototypes warnings. This patch adds
headers with function prototypes and includes the headers into
source files. This fixes the warnings like this:

warning: no previous prototype for ‘function_name’
[-Wmissing-prototypes]

This patch is needed to sync compiler warning options between meson
and makefile.

TEST=running the following produces no warnings:
meson setup --wipe (to clean build directory)
ninja test
