To protect system stability, any Binder calls leaving the
system_server must carefully be performed using FLAG_ONEWAY (or
the 'oneway' verb in AIDL) which prevents the call from blocking
indefinitely on the remote process.
In this CL, the system_server uses the new Binder.setWarnOnBlocking()
method to enable detection by default for all remote Binder
interfaces. It can also use Binder.allowBlocking() to allow
blocking calls on certain remote interfaces that have been
determined to be safe.
This CL adds the 'oneway' verb to several interfaces and methods
where it should have been added, and marks a handful of system
ContentProviders as being safe to call into. Also, we assume that
any services obtained from ServiceManager are part of the core
OS, and are okay to make blocking calls to.

voice recognition: it is always available
camcorder: "main microphone" doesn't mean anything
communication: there is no requirement for this source
to behave like the default preset.

This breaks a local refcount cycle and allows the Java gc to finalize
the Ringtone and MediaPlayer objects quickly.

Fix javadoc for stream types to indicate they are only used for
volume, not to identify streams of audio.
Do not reference AudioSystem in SDK doc.

The USB data transfer is disabled we should not allow access MTP devices
(e.g.
usb sticks). We have two ways of accessing them: Either by mounting them
or by creating a MTPDevice in an app.
Of course an app could implement implement their own MTPDevice
implementation. In this case we cannot enforce the policy without
completely suppressing all MTP USB devices which would be too
restrictive.
Note: When the policy is set we do _not_ disconnect already connected
MTP devices

A couple of MIDI device's properties (related to ALSA) are of int type
and can't be transferred as a string. Fixed the code.
As we whitelist properties that can go into native, there is no need to
expect other type of properties besides ints and strings.

* changes:
Make dispatchAudioRoutesChanged be called when BT A2DP status changed
Revert "Disable selecting the default audio route when a BT route is avaiable"
Otherwise we'll miss a trick and not take the settings provider
shortcut for playing work ringtones.

Update Java serialization code to allow interacting with native
serialization code. One notable change is due to the fact that
properties of non-primitive types can not be read back by native code,
the properties are serialized in two versions: one only contains
properties having primitive types, and another contains all
the properties. The latter is ignored by native code.
