installd: Delete cache properly for devices using datadata partition

The java side already checks /data/data for free space but installd
still checks /data causing it to never reap the cache (because it
thinks that enough free space is available.)

Monitor device storage directly in /data/data

The DeviceStorageMonitorService watches over /data, and when things get
full, starts deleting app cached files.  The app caches are actually
under /data/data, which on DINC is its own mount.  This means the
monitor did not notice when app cache grew too big, as it only saw the
size of /data proper.

This patch makes the monitor look at /data/data instead.  For DINC, this
means it can properly manage app cache, but it won't notice if the upper
/data partition is getting full.  That's not as common as /data/data
filling up though.  For the Samsung devices that mount a /datadata and
then symlink to /data/data, it should also work, as statfs dereferences
links first.  For all other devices with only /data, reading statfs on
/data/data still yields the total/free sizes of the /data partition.

SystemUI: show date on 2 lines in status bar

This allows showing of the full day of the week, and removes
the blank space above the date (which always felt strange to
me when clicking it to access the calendar).

It also fixes a spacing issue on smaller screen devices that
causes the quick settings button to be partially chopped off
when the AM/PM clock settings are enabled.

Highlight the clear button in the recents view when clicked

This commit also makes copies of the ic_notify drawables for the recents
panel to avoid any collisions with possible future changes to the
notification bar UI. (The pressed state drawable was already an unused
leftover resource).

Clean up, simplify and fix AlarmTile class and logic

This commit cleans up the AlarmTile class by removing the unnecessary
listener on the alarm intent. It now listens only to the next alarm
setting value, which was fetched after receiving the intent anyway.

These changes also fix a bug that would cause the tile to not show up
after some actions, like reordering the tiles due to the visibility not
being set on tile creation.

Lastly, some minor code styling issues have been fixed.

Patch set #2: collapse onNextAlarmChanged into onChangeUri, remove
mEnabled, use TextUtils to check for string emptiness and mark
updateQuickSettings explicitly as public.
