Log message:
   229. XFree86 loader enhancments:
        - Per-module export symbol lists.
        - Improved symbol hash.
        - A mechanism for specifying the scope of symbols.
        - Keep track of relocations, and undo them when they become unresolved
          on module unload, and recalculate them when they change on module
          load.
        - Check relocations on each module load/unload, ensuring that function
          references that are unresolved at any time are always mapped to the
          catch-all function preventing calls into nowhere.
        - Efficient handling of invariant relocations.
        - Cleanup/update the memleak stack trace code, and print a stack
          trace when an unresolved function is called or when XFree86 aborts.
        - Update the catch-all function to identify the unresolved function.
        - Read the XFree86 executable's symbol table in order to get the
          most useful stack traces, and use dladdr(), where available,
          for shared library references.
        - Cleanup and unify debug messages for the loader components.
        - Allow for module-instance-specific referenced and required
          symbols lists, so that a module's requirements can be removed
          when it is unloaded.
        - Update the ati driver to make use of some of the new loader
          functionality.
        - General loader cleanups, including removing some redundancies.
        - Don't build the coff loader on platforms that it doesn't support.
