Argument array of strings

I've been going over and tuning up the API docs, and I discovered that 
get_array_len is in fact documented as returning the number of elements 
in the array. Also, why the hell would someone want the number of bytes 
in the wire protocol!

This is _not_ on purpose just a screwup. I think we should put #ifndef 
DBUS_DISABLE_DEPRECATED around this function and introduce 
dbus_message_iter_get_n_elements() that does something useful.

Shows that even simple functions can use test coverage...
