Remove redundant includes

Remove redundant includes

The program deheader was used to create a list of redundant headers:
https://gitlab.com/esr/deheader

This change was necessary in the deheader python file:
command = maker

This script was run:

if [  $(echo $CFLAGS | grep -c "Werror-implicit-function-declaration" )
-ne 1 ]
then
	export CFLAGS="$CFLAGS -Werror-implicit-function-declaration"
fi

rm -r build
meson setup build
ninja -C build

for file in "$@"
do
	filename=${file##*/}
	filestem=${filename%.*}

	$HOME/bin/deheader/deheader -m 'ninja -C build'  -i
"$filestem.h"  "$file" # include -r for final run

	touch "$file"
done
