Initial set of 2.6.27 patches, take 3

Hi Trond-

Resending the first batch of 2.6.27 patches, with additional fixes.

Using the RPC procedure name in debugging messages should no longer add a risk of a segmentation fault.

I've also done a third re-implementation of the tk_action function name patch. I finally managed to find an interface that will perform the symbol table lookup, and can be called from a module or from built-in code.

Oddly this API has been around for a while; I'm not sure how I missed it originally. But it should implement the nice function-name-rather-than- memory-address feature without a wonky table, and without requiring any additional changes when adding a new FSM state function. It will display the function name if the lookup succeeds; otherwise it will display a hex memory address. It works for any arbitrary pointer stored in the tk_action field.

I've thought of a couple of other ways rpc_show_tasks() could be improved. First, it could display the IP address of the server handling each request; and it should have a different column layout for systems with 64-bit addresses. All for another day, I suppose.
