Handle the case where the kernel driver is in accessory mode but we failed
to initialize it at the framework level. On disconnnect, check to see if the
accessory kernel driver is enabled rather than checking mCurrentAccessory.
That way we will restore the USB state in the kernel even if mCurrentAccessory
is null.

This is used when there is only one application available and the user has
not chosen to start it by default.
If more than one application is available we continue to use UsbResolverActivity

If a USB accessory is attached and we have no application that supports it,
display a dialog offering the user the option to visit the accessory's website
if the accessory has a URI.

Permission check should only happen in openAccessory()
Otherwise an application will not be able to check for the current accessory
and ask for permissions (if it is a suitable match for the application)

If the user approves an application to access a USB device or accessory
without choosing it as the default application, then permission is granted
only until the device or accessory is disconnected.
Only applications chosen as the default choice have permissions assigned persistently.

New APIs:
UsbManager.hasPermission returns true if the caller has permission
for the given device or accessory
UsbManager.requestPermission poses a dialog to allow the user to give the caller
permission for the device or accessory.
Result is returned via a PendingIntent.
No dialog is displayed if the caller already has permission.
Also moved UsbResolverActivity to SystemUI package

If only one app is installed that supports a USB device or accessory
and that app is in the system partition, then use that activity by default
and rather than displaying the USB app chooser dialog.

When a USB device or accessory is connected, the UsbService now asks the
user which application to associate with the device or accessory.
Applications interested in devices or accessories must specify the
devices they work with via meta-data attached to their manifest.
Permission to communicate with the device is assigned when the user chooses
the activity to use for the device.
The user has the option of clicking the "always use this application" checkbox
to make the assignment automatic in the future.
The user may later clear this preference and revoke permission for an application
to have permission to communicate with the device by clicking the "Clear defaults"
button for the activity in the Manage Applications panel in Settings.
Added class UsbResolveActivity (a subclass or ResolveActivity for choosing
an activity for a USB device or accessory)
Added UsbDeviceManager, which manages the mapping between USB devices/accessories
and applications, including default applications for devices and accessories,
and manages application permissions.
Add interface to allow Settings to clear device and accessory
preferences and permissions for an application.
Remove obsolete ACCESS_USB permission.
Add new signatureOrSystem MANAGE_USB permission to allow administrating
preferences and permissions.
Moved UsbService.java to a "usb" subdirectory, along with new classes
UsbResolveActivity and UsbDeviceManager.
