Media: Make sure mVolumeController is not null

* mVolumeController is throwing NPEs all over the place in this class, which
  causes apps like Chromecast to shit the bed when using Google Play Music
  and/or Google Play Movies
* Catch additional exception on try/catch already in place and throw in a null
  check to prevent apps from crashing until null mVolumeController is rectified

Initialize pointer members to NULL to avoid illegal reference

mBitmap and mTexture is not initialized to NULL which causes
illegal address access when it fails to be created from
oversized bitmap.

Before requerying a cursor, check if it is closed.

Before updating a cursor,
it needs to be checked if it is valid.
Currently a defence code only checks
if it is not null.
But in case of "Cursor", it is not valid,
if it is closed.
So just like in CursorAdapter.onContentChanged(),
add the additional defence code to check validation.

Add NULL check in updateProxyConfig

If the exclusionList was null in updateProxyConfig the VM would
crash when converting it to a UTF8 string. Avoid this by adding a
null check.

MountService listeners can not be unregistered

When unregistering MountService listeners, their Binder proxy
objects were compared to registered listeners instead of their
backing objects.

Fix preference puts with "null" values.

Null values were being written out as <null /> elements in the
XML prefs file (as expected). This allowed the getFoo() functions
to work correctly because they treated null values as missing mappings
but containsKey would fail.

onAccountsUpdated shouldn't be called back after listener unregistered

There is a problem of AccountManager that onAccountsUpdated() is
called back even after the OnAccountsUpdatedListener is unregistered.
It may cause application crash.

For example, when rotating a tablet 180 degree with Settings apk
running, com.android.settings.Settings is re-launched 2 times
successively. (Destroy->Create->Destroy->Create)
It repeats adding&removing OnAccountUpdatedListener.

When dialog was being opened in the following cases,
NullPointerException at BackStackRecord.getBreadCrumbTitle()
was happened on 10 inch tablet which has 2 panes on Settings.
* Settings > Language&input > Language
* Settings > Language & input > Text-to-speech output > Speech rate
* Settings > Wi-Fi > Menu > Advanced > Keep Wi-Fi on during sleep
* Settings > Wi-Fi > Menu > Wi-Fi Direct > Rename device

This fix prevents the undesirable callback.

ProcessList: use different polling interval when screen off

We are using the same time interval for both screen off and screen on.
For process on top: ActivityManager.PROCESS_STATE_TOP, we will poll PSS
information every 120 sec.
During polling PSS, we are grep /proc/%d/smaps which is a 10k lines file.
This cost quite a lot of CPU resource. But when screen off, we don't need to update
TOP process PSS so frequently since we are not operating it. Lower polling
circle to every 15min to reduce power.

Fix visibility of multiple non-fullscreen activities.

Issue detail:
Assume X, Y are non-fullscreen activities.
 a.Home starts an activity X in task A in application stack.
 b.X starts an activity Y in <task A> or <new task B>
 c.Activity X will be invisible.

How to fix:
Because the function "isActivityOverHome" means an activity is able to see home.
But there may have many non-fullscreen activities between the top non-fullscreen activity and home.
If flag "behindFullscreen" is set, those middle activities will be invisible.
So it should only take care from who is adjacent to home.
Then check two flags frontOfTask(task root) and mOnTopOfHome for constraining the condition.

Add explicit close of Scanner input

The UsbDeviceManager is using a Scanner to identify
the ALSA card/device numbers to use for USB Gadget
audio, with a FileInputStream as its input.

Since FileInputStream implements the Closeable interface
it provides a close() method that should be explictly
called in order to close the stream source and release
any system resources that it might hold.
