In that case I'd prefer at this point to leave the the symbol-file
passing out. Instead just stick to a single simple qSymbol packet. The
behavour would be:

To start a transaction sequence:

-> qSymbol

It could even be:

-> qSymbol::

If you want simplicity and consistency.

The reply would be as you proposed:

<- ""
Not recognized
<- "OK"
Recognized but not now
<- <the-I-want-a-symbol-address>
As you've described

From then on it is:

-> qSymbol:<addr>:<symbol>

I don't think it is a good idea to try to include a mechanism for
passing back and forth the name of an object file until there is a
demonstrated need for such a feature.

The reason for this is that, in the past GDB has incorporated what look
like very reasonable idea's only to find that, when someone uses them,
they are insufficient.
