- Invoke MOD_QUIESCE on all modules in a linker file (kld) before

  unloading any modules.  As a result, if any module veto's an unload
  request via MOD_QUIESCE, the entire set of modules for that linker
  file will remain loaded and active now rather than leaving the kld
  in a weird state where some modules are loaded and some are unloaded.
- This also moves the logic for handling the "forced" unload flag out of
  kern_module.c and into kern_linker.c which is a bit cleaner.
- Add a module_name() routine that returns the name of a module and use that
  instead of printing pointer values in debug messages when a module fails
  MOD_QUIESCE or MOD_UNLOAD.
