Replaced VelocityTracker with a faster and more accurate
native implementation. This avoids the duplicate maintenance
overhead of having two implementations.
The new algorithm requires that the sample duration be at least
10ms in order to contribute to the velocity calculation. This
ensures that the velocity is not severely overestimated when
samples arrive in bursts.
The new algorithm computes the exponentially weighted moving
average using weights based on the relative duration of successive
sample periods.
The new algorithm is also more careful about how it handles
individual pointers going down or up and their effects on the
collected movement traces. The intent is to preserve the last
known velocity of pointers as they go up while also ensuring
that other motion samples do not count twice in that case.

UsbDevice is now just an immutable parcelable object like UsbInterface and
UsbEndpoint.
All IO related functionality is now contained in UsbDeviceConnection
and UsbRequest.

UsbManager:
- is now a service retrievable via Context.getSystemService(Context.USB_SERVICE).
- provides support for returning a list all connected USB devices
- broadcasts ACTION_USB_DEVICE_ATTACHED and USB_DEVICE_DETACHED when devices
are added and removed from the USB host bus
UsbDevice:
- represents an attached USB device.
UsbInterface:
- represents an interface on a USB device
- devices may have multiple interfaces if they provide multiple
sets of functionality (for example, android phones typically have interfaces
for both USB mass storage and adb)
UsbEndpoint:
- represents an endpoint on a USB interface
- endpoints are used for sending or receiving data
(only in one or the other direction)
UsbRequest:
- encapsulates a send or receive request to be sent over an endpoint

This enables the system bar to carve out a region through which

NFC service is now an application service in packages/apps/Nfc.
NFC service is registered through ServiceManager.addService(), and the proxy
object NfcAdapter obtains a handle to it through ServiceManager.getService().
**Important** Had to add new symbols AID_NFC / NFC_UID / android.uid.nfc and
modify service_manager.c, Process.java and PackageManagerService.java in order
to force the com.android.nfc process to take a fixed uid, so that it can use
ServiceManager.addService().
Most of the JNI has moved to packages/apps/Nfc/jni. However NdefRecord and
NdefMessage require some in-process native code, so android_com_NdefMessage.cpp
and android_com_NdefRecord.cpp stay in frameworks/base/core/jni. They link to
a very small library libnfc_ndef.so that implements NDEF message parsing. This
has been added to core.mk so all devices (even without NFC hardware) can work
with NDEF data.

1. Rename LargeBitmap to BitmapRegionDecoder
2. Move the instantiations of BitmapRegionDecoder out of BitmapFactory.
3. Remove the use of MemoryFile in BitmapRegionDecoder, since MemoryFile's API had been modified in master. Otherwise, the change will break the master build.
4. Move AssetStreamAdaptor, AutoFDSeek and nullObjectReturn to Utils.h because BitmapFactory.cpp and BitmapRegionDecoder.cpp both need to use these utility functions.
Most of the modifications, except for (2) and (3), were reviewed in https://android-git.corp.google.com/g/#change,64716 .
However, that change broke the master build due to (3) and was reverted eventually.
So, instead of withdrawing this change and waiting for that change to be checked in again, I merge the two changes into one.

The makefile variable USE_OPENGL_RENDERER must be set to true to compile
libhwui and the related code in the JNI layer.
This change also removes obsolete APIs from Canvas that must not be used
and would be confusing if left in. These APIs were remnants of our first
attempt at an OpenGL renderer for the view hierarchy and had not been
taken out before Android 1.0 was released.

The goal here is to avoid the dalvik.vm.* property explosion by
having a single property that takes an arbitrary collection of Dalvik
command-line options. This is intended for testing of various
configurations by the Dalvik team, not industrial use.
Options should be separated by spaces, e.g.
adb shell setprop dalvik.vm.extra-opts "-showversion -Xmx4m"
will print the version banner and set the heap max to 4MB, which won't
get you very far.
The extra-opts options will appear last, which allows them to override
values set earlier (like the heap max).

Rather than polling for events from the native code in an event thread,
we now require the GPS HAL libraries to call our callbacks from a thread
that is registered with the JVM to call directly into Java.
This eliminates a thread from our code and removes one step in the chain
of message passing from the GPS to the Location Manager client.
