"set pagination off".

If you're referring to script-generated output, I don't think we
currently have a way to print unfiltered.

You need a newer gdb.  lookup_symbol was added after 7.1.

I think with a newer gdb you could compute this info from Python.

I don't think there is a way.
It would be reasonable to add something.

I think question #5 is implicitly answered by the above...

Yes, see "set script-extension".
