Audio: Fixed system/call stream volume can't adjust with HS connected.

Issue Description:
When headset connected, the system/voice call stream volume can't be
adjusted from Volume bar.

Root Cause:
Currently adjustStreamVolume is applied to stream type alias and the
device for the stream alias. So when headset connected and adjust
volume for SYSTEM_STREAM, the operation will be applied to RING_STREAM
(which is aliased by SYSTEM_STREAM) and speaker. As headset is returned
from getDeviceForStream(SYSTEM_STREAM), but speaker for RING_STREAM.

Solution:
Change the adjustStreamVolume to apply volume to the stream alias and
the device for the stream type exactly.

AudioService: Show safe volume panel for non-interactive volume adjustments

If safe volume is active, apps calling mp.setVolume() to adjust the
headset to a value higher than the threshold will have the operation
fail silently because no volume dialog is active to pop up the
"do you wish to override" question.
This is particularly bad for peripherals that use the audio jack
(Square readers, Jawbone bands), since they usually require levels
close to maximum for proper communication and the app isn't prepared
to deal with a silent rejection of the requested volume.

GlobalActions: Fix possible race condition when showing dialog.

Depending on the presence of a previous dialog, the newly generated one
gets either immediately displayed (no old dialog) or shortly delayed
(after dismissal of the existing one).
If a new show event happens (by rapid fire of the power key, for instance,
using a keyboard with fast-repeating events) during that delay, a new
dialog will be immediately displayed, and when the delayed show triggers
it'll conflict with it (and bring everything down).

This moves the creation of the new Dialog object to _before_ showing
it (delayed or not), instead of the show method itself, to ensure the
object isn't clobbered by competing/sequential calls to handleShow()

Remove unnecessary updateSurfaceScreenOn call.

This change stops updateSurfaceScreenOn() from being called one time
right after another. It's called at the end of stayAwake(boolean awake),
which is called right before updateSurfaceScreenOn() in release().
