Some camera HALs spin up a preview thread and need to wait for
the thread to exit. This can create a potential deadlock. In
stopPreview, we take the main lock. If a preview callback occurs
while the lock is held, the preview thread will block. If the
camera HAL is waiting for the preview thread to exit, this will
cause a deadlock.
This patch breaks out the preview buffer heap into a separate
mutex. This mutex is never held when the main lock is held, thus
preventing the deadlock from occuring.
* changes:
Make the RegisteredSErvices Cache not allow the registered service for a type to change without first uninstalling the previous service for that type, unless the newly installed service is in the system image.
type to change without first uninstalling the previous service for that
type, unless the newly installed service is in the system image.
Notify the listener when a service is added or removed.
Make the AccountManagerService remove the accounts for an authenticator
when the registered authenticator changes from one uid to another.
Make the AbstractSyncableContentProvider force a sync when the database is first created.
The third parameter count of PrivateOutputStream.write()
should be the size of vcards data plus header length, excluding the 3 bytes
for the response message and 3 bytes for the header ID and length.
Adjust the return value of getMaxPacketSize() by minus headser size, so that
applications should not get packet slipped during multiple sharing operation.
Do not set the header to null in getHeaderLength() to get PBAP PTS passed;
Per OBEX spec, for Get request:
Only the last packet need send the 0x49(End of Body);
for intermediate packets, we need to send 0x48 (Body).
If all packets use 0x49, some carkit like Nokia PD-17 will fail to download
all contacts, except data in the last packet.

Make sure to deliver events to the wallpaper until the final up.
Also fix behavior in the case where a window goes away while the pointer is still
down in it, which is a fairly novel situation introduced by the new lock screen.
Also add infrastructure for delivering motion events during preview.

* changes:
Fix for random audio output failures, properly dup() the file descriptor in IMediaPlayer::setDataSource to assume ownership as the caller will otherwise close it.
This allows the driver to behave differently depending on if the lighting is being
managed by the light sensor or by a user preference.

There were potential deadlocks between the per-GLThread monitors and the
GLThreadManager monitor.
To avoid these deadlocks we now use a single monitor for
both the GLThreadManager state and the per-GLThread state.
Converted GLThreadManager's semaphore into the equivalent
synchronized-wait-notifyAll code. This enables us to wait for
either mDone, or user events, or the EGL surface with a single "wait()".
Simplified the logic used to acquire and release the EGL surface. The
EGL surface is now only requested while the surfaceFlinger surface
is acquired.
Removed the "egl surface stealing" policy we had recently inserted.
It's not needed now that we reliably quit when requested.
Pulled user event processing outside of the GLThreadManager monitor
so that we don't call any potentially-long-running code while
inside the monitor.
This should help with bug 2228262.

To prevent buggy command implementations from poisoning binder threads'
scheduling class & priority for future command execution, we now reset the
cgroup and thread priority to foreground/normal when a binder service thread
finishes executing the designated command.

We currently only allow one GLThread to have an active EGL Surface at a
time.(This may be lifted in the future, when EGL and GL are reentrant.)
Prior to this change we would enforce this rule by having older GLThreads
quit when a new GLThread started. That had the drawback of leaving the
older GLSurfaceViews in a zombie state -- their GLThreads would be
gone.
We now enforce this rule by just releasing and reacquiring the EGL surface
context as needed.
Specific changes to the code:
created private helper methods - startEgl and stopEgl to help manage
starting and stopping EGL.
Move the calls to sGLThreadManager start and end from the outermost run
method into the startEgl / stopEgl methods.
Reworked the wait loop to handle starting and stopping EGL as needed.
needToWait() gets simpler -- just looks at current status.
sGLThreadManager.shouldQuit was replaced by shouldHaveEgl.
This is another step in fixing bug 2228262.
