Just found that proto/cli.h doesn't build if types/cli.h is not also
included by the caller, as it uses cli_kw_list is used in arguments.
But it's also true for a few other ones like mworker_proc, stream,
and channel, so let's fix this.
#ifndef _PROTO_CLI_H
#define _PROTO_CLI_H
+#include <types/applet.h>
+#include <types/channel.h>
+#include <types/cli.h>
+#include <types/global.h>
+#include <types/stream.h>
+
void cli_register_kw(struct cli_kw_list *kw_list);
