Squash: Memory leaks, NPEs, races and optimizations for fw/base

This is a combination of 13 commits.

The first commit's message is:

Fix a programmatic smooth scroll bug

Bug: smoothScrollToPosition() stops at child view of which height is
higher than list view itself.

This is the 2nd commit message:

Fix infinite recursive loop

There is an apparent recursive loop at IntProperty.java
in method set(Object, Integer)

This method unconditionally invokes itself. This would seem
to indicate an infinite recursive loop that will result in a stack overflow.

This was brought over from out original JB branch.  Somehow, this got
overlooked, and never made it into JB42.

This is the 3rd commit message:

Rework thumbnail handling

Since ids of media file are usually not continuous, the original file of thumbnail are
sparse. When there are big numbers files on ex\
ternal storage, the size of this file will be horrible.
Ex, when the id is 20000, then the .thumbnails/.thumbdata3-xx file will be 50000*10k = 488.28M.
Can refer http://stackoverflow.com/questions/12396715/android-huge-thumbdata4-file-in-dcim-folder
Because after 4.0, MediaProvider will scan any files, this will be a big problem. So I modify MiniThumbFile.java to avoid this.
According to the id, we now produce an index file. In this index file, one id will use BYTES_PER_MINTHUMB_INDEX(8) bytes in offset (i\
d+1)*BYTES_PER_MINTHUMB_INDEX. The data of these 8 bytes is the index of thumbnail file. The first BYTES_PER_MINTHUMB_INDEX bytes kee\
p next available index. And when you need insert a thumbnail, the index increase by 1. In this way, the block data in thumbnail file \
will be continuous. And thus unnecessary zero paddings will not be saved.

This is the 4th commit message:

frameworks/base: Fix for the race in Wallpaperservice

Wallpaperservice has a race among message handler of
DO_DETACH and service's onDestroy. In certain cases,
the engine kept track in mActiveEngines is removed by
message handler of DO_DETACH and service's onDestroy
doesn't get a entry in mActivieEngines and isn't able
to invoke detach. This keeps the broadcast receiver,
mReceiver active and is unregistered by the framework
and a corresponding leak is reported.

  Later, the message handler of DO_DETACH continues
and invokes detach on mEngine, which attempts to
unregister mReceiver and framework throws an exception
"Receiver not registered: android.service.wallpaper.
WallpaperService$Engine$1@40874580" and causes the
framework to reboot.

  In case of system_server, WindownManagerPolicy and
android.server.ServerThread contest for access of
shared members, mActiveEngines and mEgine. Fix is to
protect the critical section via synchronized block.

This is the 5th commit message:

Make EntropyMixer mix in output of Hardware RNG into Linux RNG.

On devices with Hardware RNG (HW RNG), this makes EntropyMixer
periodically (every three hours) read 512 bytes from HW RNG and mix
them into the Linux RNG.

This is done without increasing Linux RNG's entropy estimates to
avoid having to trust the quality of the HW RNG. This approach cannot
reduce the quality of the Linux RNG output, but may increase it.

This is the 6th commit message:

build core/jni with fstrict

This is the 7th commit message:

Reduce EntropyMixer seed size from 4096 to 512 bytes.

The suggested seed size from Linux drivers/char/random.c is 512 bytes
rather than the 4096 bytes currently used.

This is the 8th commit message:

frameworks/base/: Fix black wallpaper issue when home pressed.

In the specified usecase, there is a completely new set of
windows that appear on the screen during rotation. And the
existing code in the framework ignores the drawstate of the
hidden windows.

Wait till the drawState is ready for the hidden windows also.

This is the 9th commit message:

Fix to NullPointerException when activity is relaunched

When ChooseTypeAndAccountActivity is relaunched and resumed
by ActivityManager a call is made to onActivityResult without
first triggering onResume. This leads to mAccounts object
still being null.

Fixed by properly setting mAccounts object if it is null prior
to use after function onCreate has been called.

This is the 10th commit message:

Remove possible leak when exception occurred.

nameUtf8 is not released after exception.
In addtion, Fix code going down after ThrowException.

This is the 11th commit message:

frameworks/base: Fix to remove exception in tonegenerator

- Framework reboot happens, if tonegenerator fails to create
  a track in audioflinger.
- The cause for framework reboot is, an exception thrown by
  tonegenerator if fails to init.
- Fix is to remove the exception and delete the tonegenerator
  instance.

This is the 13th commit message:

frameworks/base: move the traces file to avoid data loss

If an ANR comes just after the framework reboot, the traces for
the framework reboot will get over-written with the ANR traces.
So, We are missing the traces for the framework reboot which
makes debugging the framework reboot difficult.

This patch will rename this trace file for the framework reboot
once the ActivityManager collects the traces.

fw/base: MOAR misc fixes & enhancements

Make ImageView drawable update more efficient in some cases.

When updating the view's drawable via setImageResource or setImageURI,
make sure to skip the layout pass if the old and new drawable have equal
sizes. This follows what is already done for setDrawable().

Fix a bootloop problem when /data/system/usagestats/usage-history.xml is empty.
This often occurs after an incomplete reboot/shutdown or battery pull.

ActivityManagerService: stay away from zombie content providers

When the lowmemorykiller kills a content provider in an unfortunate
moment, an innocent client app can become attached to a zombie provider
and be unconditionally killed moments after, when the dead provider is
being removed.
Prevent this race by addition of isAlive function to Process.java that
determines whether a process is still running and is not only a zombie,
add a check of the state of the provider process to getContentProviderImpl.

bootanim: Don't cache textures if they're expected to use a lot of VRAM

bootanimation cached all the textures generated until the animation
was completed.
For Hi-res animations with lots of frames (like the new CM9 anim on
xhdpi devices), this implied using large amounts of video RAM, more
than most devices actually have available, causing the animation to
stall (and in some cases, gralloc to lock up); so if an animation is
expected to use a lot of RAM (rough estimation based on frame size
and number of frames), disable cache entirely and generate the textures
on demand

bootanimation: performance enhancements

This patch implements two simple performance enhancements, which
might benefit devices. They are completely opt-in by setting
the following variables.

  * TARGET_BOOTANIMATION_PRELOAD: will preload the bootanimation
    zip to memory; this is handy on devices where the storage
    might be slow. By preloading it, we get quick access to the
    zip file, and the animation doesn't stutter.

  * TARGET_BOOTANIMATION_TEXTURE_CACHE: allows maintainers to
    force texture cache on/off.

Also fixes the sign warnings related to int / size_t comparison

bootanimation: fix usage of LOGW

bootanimation: allow using RGB565 instead of ARGB8888

RGB565 uses considerably less memory, and together with texture
cache, it allows us to offer a really smooth bootanimation on
not so powerful devices.

audio: libaudioeffect_jni GREF leak fix

- Excessive JNI global reference in AudioEffects.
- Global references created during native setup
  are not deleted.
- Global references are deleted in setup failure
  and during native release.

MiniThumbFile: Fix image/bitmap retrieval

Change I66005dd69b0a5c8f4353bd7a8225d163a654fd2d changed the insertion
and creation indexing mechanism, but the retrieval method was still
using the old sparse one. Fixit

android.provider.cts.MediaStore_Images_MediaTest#testInsertImageWithImagePath,
android.provider.cts.MediaStore_Images_ThumbnailsTest#testQueryExternalMiniThumbnails,
and android.provider.cts.MediaStore_Video_ThumbnailsTest#testGetThumbnail

Memory leak in IInputMethodSessionWrapper executeMessage

In some cases the executeMessage is called with
mInputMethodSession == null. For the messages

DO_UPDATE_SELECTION, DO_APP_PRIVATE_COMMAND

memory is leaked. This commit recycles the args freeing
the allocated memory.

Fix resource leak: When call MediaMetadataRetriever.setDataSource or getFrameAtTime should ensure call release in finally to avoid resource leak
                   Patch set 2: Remove unnecessary white spaces

Fix certain setting writes being incorrectly skipped.

If a value that previously had a very long value (over the 500 char
threshold) is now set to null, isRedundantSetValue would incorrectly
return true even though the value was changed.
