[arch-general] xinitrc.d framework

[Muhammed Uluyol]

I think it would be better if it was more like rc.conf by using an
array and a function that went through that array. It looks simple
enough, maybe something like
exec_xinitd_scripts() {
    if [[ $XINITD_SCRIPTS ]]; then
        for ((i=0; i < ${#XINITD_SCRIPTS[@]}; i++)); do
            exec_next_xinitrc "${XINITD_SCRIPTS[i]}"
        done
    fi
}

and put
XINITD_SCRIPTS=(consolekit something somethingelse)
exec_xinitd_scripts
in $HOME/.xinitrc
