Fix the default value for long press on home.

In AOSP the values for this option are different than in CM.
Switch it back to the CM value for opening recent apps.

AudioService: Restore volumes after boot and when a headset is plugged

The correct volume levels for <device>_speaker and <device>_headset are not
restored after booting and when a headset device is plugged in or out.

This fixes a glitch where the first volume change event causes the volume to
be reset to the last stored value instead of increasing/decreasting it by
one step.

Move 'start music player on headset connection' option out of DSPManager
(1/2)

This option isn't related to DSP manager at all, so it shouldn't be
implemented there.

Fix up 'launch player on headset connection' option.

- don't crash system_server if no music player can be found
- use the active user's setting instead of the owner's setting
