gtalk and sip already use the high perf lock. Improve
the comments and make the constant public.
This will allow applications that use voice or video
to keep the connection good even when device screen
is off

USB accessories are peripherals that connect to android devices as a USB host.
When connected, the accessory will first identify itself to the android device
by sending manufacturer, product, accessory type and version strings
to the device, and then request the device to enter USB accessory mode.
The device will then enable the USB accessory kernel driver and disable
all other USB functionality except possibly adb
(adb can be used while the android device is connected to the PC
and the PC is running software that emulates a USB accessory)
The class android.hardware.UsbAccessory is used to describe the
currently attached USB accessory.
UsbAccessory contains the manufacturer, product, accessory type
and version strings to identify the accessory.
The accessory can be opened as a ParcelFileDescriptor, which can be used
to communicate with the accessory over two bulk endpoints.
The Intents UsbManager.USB_ACCESSORY_ATTACHED and
UsbManager.USB_ACCESSORY_DETACHED are broadcast when accessories are
connected and disconnected to the device. The USB_ACCESSORY_ATTACHED
contains a UsbAccessory object for the attached accessory as an extra.
The Intent also contains string extras for the manufacturer, product,
accessory type and version strings to allow filtering on these strings.

This change makes it possible to extend the set of axes that
are reported in MotionEvents by defining new axis constants.
The MotionEvent object is now backed by its C++ counterpart
to avoid having to maintain multiple representations of the
same data.

@hides the View constant that designates a drag as cross-app, and also
forcibly ignores that flag on the system_server side even if it's passed
to startDrag() as a literal.

Bitmap.setHasAlpha() in particular is very useful for applications that use
ARGB_8888 bitmaps but want/need to benefit from an extra speed boost.

Cherry-pick from GB to HC, updating 11.xml.
Final final final Gingerbread MR API changes.
This is it. I promise.
ACTION_TECHNOLOGY_DISCOVERED -> ACTION_TECH_DISCOVERED
This was missed in our technology->tech rename.
Hide TagTechnology.reconnect()
This is used to reset any per-connection state in a tag, by reconnecting
to it. The first problem is that it belongs on Tag, not TagTechnology. The
second problem is that it may become redundant once we add Tag.rediscover()
which will also reconnect to the tag, and will also return a new Tag with
newly created technologies enumerated. And the third and most significant
problem is that you can already achieve the same result by just calling
close() followed by connect().
Hide Tag.createMockTag()
This API cannot be used reliably. First it requires using int[] for the
technology list, but those int constants are now hidden. Second it requires
knowledge of the extras parcel used to fill technology specific data - also
not public.
Introduce TagTechnology.isConnected()
Every child class already impelmented this, and given that connect() and
close() are defined on the interface, then isConnected() should be there
too.
Modify Ndef.getType to return a string (not int)
Allows more flexibility in adding new NDEF types. Current public strings are
org.nfcforum.ndef.type1
org.nfcforum.ndef.type2
org.nfcforum.ndef.type3
org.nfcforum.ndef.type4
com.nxp.ndef.mifareclassic
Add NdefFormatable.formatReadOnly()
This allows you to make the tag read-only at the same time as performing
format and write. It is important because we currently don't have any
public API to re-enumerate a tag technology list after making a tag
NDEF compatible, so you can't perform the format as a seperate step
without physically removing the tag from field and returning it.
Modify Readonly -> ReadOnly
Make Tag class final

...an already-closed object: android.database.sqlite.SQLiteQuery
It turns out there is a state we are missing -- the loader is
still needed, but in the inactive list. In this case the loader
needs to continue holding on to its current data, and not deliver
any new data (which would result in it releasing its old data).
This introduces the new state to Loader, and uses it in
AsyncTaskLoader so all subclasses of that should get the new
correct behavior.
A further improvement would be to unregister CursorLoader's
content listener when going in to this state, but that can
wait for later.

Also adds a new flag constant, View.DRAG_FLAG_GLOBAL, which indicates that
the drag operation should be allowed to propagate the drag outside the
originating app. When this flag is specified, all visible windows will
be notified about the ongoing drag.
