Prevent Lockscreen album art from activating FLAG_KEEP_SCREEN_ON

This is a small fix to the showWallpaper method, in which a power
consumption problem has been introduced. This showWallpaper method
toggles the window flag FLAG_SHOW_WALLPAPER, when album art is being
shown in Lockscreen. It is important to set pixel format to
PixelFormat.OPAQUE if flag FLAG_SHOW_WALLPAPER is not being set.

If not, an application that uses window flag FLAG_KEEP_SCREEN_ON
will prevent the keyguard from going to sleep and drain battery.

AudioService: Fix absolute volume for AVRCP

Avrcp.java uses max volume obtained by getStreamMaxVolume() when
converting to AVRCP levels and it returns non-scaled volume index.
For this reason volume index needs to be dispatched to Avrcp before
scaling as otherwise Avrcp will convert volume level incorrectly,
i.e. max volume index for music stream is 15 and any volume index
>1 (>10 after scaling) will result in setting *MAXIMUM* volume level
on headset which is not safe for listener.

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.
