Fixed up disassembly to not emit the module name before all function names 

that are in the disassembly comments since most of them are in the same
module (shared library). 

Fixed a crasher that could happen when disassembling special section data.

Added an address dump style that shows the symbol context without the module
(used in the disassembly code).
