Bug 18364

	Some functions use a macro SYSCTL_HANDLER_ARGS but no tag command
	can detect them as functions, because function's braces are hidden
	in the macro.
	SYSCTL_HANDLER_ARGS is like this:

		#define SYSCTL_HANDLER_ARGS (struct sysctl_oid *oidp, void *arg1, int ar
			struct sysctl_req *req)
		...
		int sysctl_handle_int SYSCTL_HANDLER_ARGS;


	Instead, it should be like this:

		#define SYSCTL_HANDLER_ARGS struct sysctl_oid *oidp, void *arg1, int arg
			struct sysctl_req *req
		...
		int sysctl_handle_int (SYSCTL_HANDLER_ARGS);

Fix:
