Improve scrolling cache

Scrolling cache helps make short scrolls/flings smooth but will
cause stutter when long flings are made. This patch disables
scrolling cache when long flings are made.

This patch also fixes a related bug where scrolling cache will
not be enabled properly when transitioning from flinging to scrolling.

Patch Set 2: Calculate threshold based on maximum velocity (Sang Tae Park)

Fix to NullPointerException when activity is relaunched

When ChooseTypeAndAccountActivity is relaunched and resumed
by ActivityManager a call is made to onActivityResult without
first triggering onResume. This leads to mAccounts object
still being null.

Fixed by properly setting mAccounts object if it is null prior
to use after function onCreate has been called.

Keyguard: Set WIDGET_CATEGORY_KEYGUARD when AppWidgetHostView is created

Allows the default lockscreen widget to inherit the keyguard widget
host category.  Without this, only widgets added through
KeyguardActivityLauncher are assigned the correct
OPTION_APPWIDGET_HOST_CATEGORY.

Wifi: Fix for connection failure between third client and GC.

When third device sends a connection request to the group client, the
existing connection is terminating and also the ongoing connection not
successful.Currently as there is  no use case where third device is
connecting to GC,and the existing onnection getting terminated.This
is addressed by ignoring the new connection request from third client
to GC and the existing connection is intact.

frameworks/base: move the traces file to avoid data loss

If an ANR comes just after the framework reboot, the traces for
the framework reboot will get over-written with the ANR traces.
So, We are missing the traces for the framework reboot which
makes debugging the framework reboot difficult.

This patch will rename this trace file for the framework reboot
once the ActivityManager collects the traces.

within the android namespace.
Explicitly specify which std classes are necessary to prevent ambiguous
