Rewrite jack presence detection and implement automatic recording source

Browse Source 
selection in snd_hda(4) driver.

Now driver tracks jack presence detection status for every CODEC pin. For
playback associations, when configured, that information, same as before,
can be used to automatically redirect audio to headphones. Also same as
before, these events are used to track digital display connection status
and fetch ELD. Now in addition to that driver uses that information to
automatically switch recording source of the mixer to the connected input.

When there are devices with no jack detection and with one both connected,
last ones will have the precedence. As result, on most laptops after boot
internal microphone should be automatically selected. But if external one
(for example, headset) connected, it will be selected automatically.
When external mic disconnected, internal one will be selected again.

Automatic recording source selection is enabled by default now to make
recording work out of the box without touching mixer. But it can be
disabled or limited only to attach time using hint.pcm.X.rec.autosrc loader
tunables or dev.pcm.X.rec.autosrc sysctls.
