this is needed for backward compatibility with somewhat buggy applications.
not a big deal, since the app can request another format explicitely.

thus eliminates the sharing of the message dispatches between omx instances.
If the omx audio and video encoders share the same dispatcher, when the audio read
blocks in the AudioSource, the message dispatcher thread gets blocked. As a result,
the message for the omx video encoder can not be dispatched, hence gets blocked too.
If the blocking time is long enough, the video frame rate decreases significantly.
This is the case when we read 2048 bytes by default each time. Reading smaller blocks
of audio data helps mitigate the above-mentioned problem, but it is not an ideal
solution for two reasons: a) it is not efficient, and thus can cause a lot of overhead
passing buffers between the frame work and the omx encoders; b) also, the audio record
thread can overflow as a result, which lead to the loss of recorded audio frames.
This patch affects both authoring engine and the playback engine.

Previously tests/framework-tests contained a quarantined set of test classes
that needed access to package-private framework api. Running these tests
normally would cause the dalvik verifier to throw errors.
runtest now has support for turning off the dalvik verifier for frameworks
tests, so move this tests into their recommended location, close to the source
being tested.
Also move policy source into a 'src' folder to accommodate the tests move.

Native input dispatch rewrite work in progress.
The old dispatch mechanism has been left in place and continues to
be used by default for now. To enable native input dispatch,
edit the ENABLE_NATIVE_DISPATCH constant in WindowManagerPolicy.
Includes part of the new input event NDK API. Some details TBD.
To wire up input dispatch, as the ViewRoot adds a window to the
window session it receives an InputChannel object as an output
argument. The InputChannel encapsulates the file descriptors for a
shared memory region and two pipe end-points. The ViewRoot then
provides the InputChannel to the InputQueue. Behind the
scenes, InputQueue simply attaches handlers to the native PollLoop object
that underlies the MessageQueue. This way MessageQueue doesn't need
to know anything about input dispatch per-se, it just exposes (in native
code) a PollLoop that other components can use to monitor file descriptor
state changes.
There can be zero or more targets for any given input event. Each
input target is specified by its input channel and some parameters
including flags, an X/Y coordinate offset, and the dispatch timeout.
An input target can request either synchronous dispatch (for foreground apps)
or asynchronous dispatch (fire-and-forget for wallpapers and "outside"
targets). Currently, finding the appropriate input targets for an event
requires a call back into the WindowManagerServer from native code.
In the future this will be refactored to avoid most of these callbacks
except as required to handle pending focus transitions.
End-to-end event dispatch mostly works!
To do: event injection, rate limiting, ANRs, testing, optimization, etc.

If soft AP bring up does not go through successfully,
dont persist the config. This has the benefit of recovering
from the case where things fail on "=" and "," for SSID since
the IOCTL parsing in driver on broadcom cannot handle it
at this time.

Modify OOM adj classes a bit, to take into account the new
heavy weight app type, and give "foreground services" their
own category to have a bettery chance to manager them when
things go wrong.
Also add some new code to battery stats to keep a history
of changes to the battery level.

Added AudioEffect C++ class. AudioEffect is the base class for effect specific implementations,
OpenSL ES effect interfaces and audio effect JNI.
Added the AudioEffect JNI and AudioEffect JAVA class. AudioEffect is the base class
to implement more specific JAVA classes to control audio effects from JAVA applications.
