debugger add-on set a demangle hook, all modules under debugger/demangle/ are
now considered demangle modules.
* Added another function to the demangle module interface that gives you access
to the arguments.
* Implemented a demangling module for GCC2.
* The older demangling module is now called "gcc3+", but doesn't support
getting the arguments yet.
* The "call" KDL command is now using demangling to automatically show you
the arguments of a call from a stack crawl.
* Minor cleanup.
