Put PUBLIC lines in Mac symbol files.

Browse source 
Exported symbols on Mach-O binaries are defined in a STABS section. This patch makes stabs_reader handle them, adds support for Extern symbols in the Module class (which are output as PUBLIC lines in symbol files), and the proper processing in stabs_to_module to hook it all up.
