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.

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.

Fixed race condition in Spinner.DialogPopup on null reference.

NullPointerException is triggered when DialogPopup is
dismissed due to object mPopup being null when not showing.
Race condition is triggered when dialog is dismissed before
touch event to dismiss dialog has been processed properly.

Fixed by adding a null check prior to accessing mPopup object.

Fix error checking in MemoryFile.

mmap returns MAP_FAILED on failures, not 0 (NULL).
Also, convert some C style casts to C++ since they
make intent clearer.
