[PATCH] Make `obsolete params' work correctly if MODULE_SYMBOL_PREFIX is non-empty

[Miles Bader]

Since these are just symbols in the module object, they need symbol name
munging to find the symbol from the parameter name.

[I guess using the stack is bad in general, but parameter names should be
very short, and hey if they're obsolete, it seems pointless to spend
much effort.]
