Make an exception for screenshot optimization.

Screenshots were not being made for tasks with the flag
FLAG_EXCLUDE_FROM_RECENTS set. But if the task is in the foreground
the shot should be taken even with the flag set. This fix adds a test
for tasks being in the foreground.

Fixes bug 11170567.

Remote volume changes

When the user plays media remotely, and presses on the volume
 keys with the screen off, verify whether not only local playback
 is active, but also if remote playback is active to see if
 the volume should be adjusted.
When adjusting the volume with screen off, adjust the remote
 volume if applicable.

When controlling volume, give priority to local media playback.

Print spooler not starting.

1. In my previous change I fixed a typo in the Java constant with
   intent action to launch the print dialog but failed to updated
   the print spooler manifest.

2. Removed dead code - the user id is no longer needed since the
   spooler is an app that runs per user. Every user has its spooler.
   This code was not referenced from anywhere.

3. Added a default icon to the print spooler.

4. Fixed a bug where if the print history is empty the UI goes
   to the all pritners activity.

Workaround fading edge incompatibility with alpha modulation

bug:11121809

Fading edges, such as drawn by a scrolling marquee TextView, don't
behave correctly when their view is modulated, as done by the view
system when alpha is set on a view that returns false from
hasOverlappingRendering.

To work around this, always return true from hasOverlappingRendering
if a TextView has horizontal fading edges enabled.

If the ContentResolver sync API is used with the empty ("")
string as a provider, the ContentService will throw an RTE.
This cl addresses all the entry points of the API that could
allow this, as well as adds an ifEmpty check at the point of
failure.
Also removed RTE throws from public functions(no point in
crashing the phone).
