- Fix debug info look-up (bug in translating the RVA of the debug
  directory).
- Fix code for adding PE export table as debug info (crash with NULL
  passed to RtlImageDirectoryEntryToData).
- Fix computation of non-relocatable ELF shared objects size.
- Fix loading (while parsing the link map) of new non-relocatable ELF
  shared objects (no longer take account load-address of link-map).
- Finished the AUTO_PUBLIC, NO_PUBLICS and PUBLICS_ONLY support for PE and ELF.
- Cleaned up public symbol management (which should now properly work).
