kent 297e3c5d35 Mixer changes:
- Add "outputs.surround", "outputs.center", and "outputs.lfe"
 - If the codec is not capable of a feature, mixer variables
about the feature is not created.  For example, no
"outputs.tone" for a codec without tone control.
 - Set the following mixer values in ac97_attach():
	outputs.master=127,127
	outputs.master.mute=off
	outputs.headphones.mute=off
	outputs.surround=127,127
	outputs.surround.mute=off
	outputs.center=127
	outputs.center.mute=off
	outputs.lfe=127
	outputs.lfe.mute=off
	inputs.dac.mute=off
	inputs.cd.mute=off
	inputs.line.mute=off
	inputs.aux.mute=off
	inputs.video.mute=off
	record.volume.mute=off
    because the default setting of AC'97 codec (all mutes are on,
    and maximum volume) is troublesome.
 - Make "char*" parameters of ac97_get_portnum_by_name() "const char*"

Codec ID changes:
 - If a codec ID is unknown but its vendor ID is known,
ac97_attach() prints the vendor name like "dev0: <vendor name>
unknown (0xXXXXXXXX) codec;"
 - Add IDs of Asahi Kasei AK4542, AK4544, AK4544A, AK4545,
Realtek ALC100
 - Correct a vendor name: "Advance Logic" -> "Avance Logic"
 - Add capability of codec-specific initialization

ac97_attach():
 - CDAC, SDAC, and LDAC are eanabled.
 - DELAY() before mixer settings.  ThinkPad X24 needs it.

ALC650 codec specific change:
 - Add "outputs.surround.lineinjack" to switch the line-in jack
to the surround output
 - Add "outputs.center.micjack" and "outputs.lfe.micjack" (alias
of "outputs.center.micjack") to switch the mic jack to the
center/lfe output.
