[PATCH spice-common] Marshaller: rename _add_ref() to _add_by_ref()

[Jonathon Jongsma <jjongsma@xxxxxxxxxx>]

The spice_marshaller_add_ref() family of functions is confusing since it
sounds like you're incrementing a reference on the marshaller. What it
is actually doing is adding a data buffer to the marshaller by reference
rather than by value. Changing the function names to _add_by_ref() makes
this clearer.

The old functions are deprecated and are simply inline functions that
call the new functions.
