spkr vs spkr_synth module

[Paul Goyette <paul%whooppee.com@localhost>]

I'm not sure if it's really correct to have the modules/spkr_synth.kmod 
file contain a module named "spkr".  It makes the modload/modunload 
asymmetrical (modload spkr_synth vs modunload spkr), and makes it hard 
to determine, from the output of modstat(8), which module is actually 
loaded.

I'm tempted to rearrange things, but I'm concerned about potential 
confusion.

1. Rename i386/amd64-only spkr module to spkr_pcppi and adjust the
   module name accordingly.
2. Rename spkr_synch module to spkr (leaving the module name alone).
3. Leave the device-autoload stuff alone, so the default will be to
   autoload the audio-based spkr module!
4. Add spkr, and mark spkr_synth obsolete in the modules/mi sets list;
   in the i384 and amd64 sets lists, rename spkr --> spkr_pcppi (do
   NOT mark the old spkr entry as "obsolete" since it will still exist
   based on the mi file).
5. If someone really wants to use the spkr_pcppi module, they will
   need to manually load, or include it in the kernel config (and
   remove spkr_synth).

Thoughts?
