Solve three memory leaks related to PatchCache

A Patch can be fairly large, holding bitmap data, but
is also frequently leaked which adds to the severity.
The feature is used in many important processes such
as Home, SystemUI and Chrome.

The following leaks are solved:

1. The Patch itself was not always freed.
PatchCache::removeDeferred() can mark patches to be
cared for by PatchCache::clearGarbage(). But
mCache.remove() would only destroy the container
and the pointer, not the Patch object itself.

2. The vertices stored in the Patch at Patch::createMesh()
would always leak. The empty/default destructor in Patch
would not properly destroy "vertices" since it's just a
pointer.

3. A BufferBlock that's added to the mFreeBlocks
in PatchCache could leak. The leak happened when a
patch later needed the entire free block, because the
object was removed from the list but never deleted
in PatchCache::setupMesh().

Fixed VM memory leak in AudioSystem JNI interface

The function android_media_AudioSystem_error_callback from AudioSystem
JNI interface is using FindClass function but does not delete the
reference created by VM in this function.
By doing this call, VM will add a local reference in IndirectRefTable
and it's the caller's job to delete this reference.
By not doing this, everytime this callback is called, a new reference is
added and never deleted.
The effect is crashing the VM running system_server:

E/dalvikvm( 3071): JNI ERROR (app bug): local reference table overflow (max=512)
W/dalvikvm( 3071): JNI local reference table (0x732da288) dump:

E/dalvikvm( 3071): Failed adding to JNI local ref table (has 512 entries)

E/dalvikvm( 3071): VM aborting

In this case, PID 3071 is system server.

Fix a resource race bug in PathCache

When enabled defer rendering, it will do precache for DrawPathOp.
The paint used for creating PathTask in precache just get the address
of mFilteredPaint of OpenGLRenderer. So for the following defer
operation like DrawTextOp has possibility change the mFilteredPaint
by getPaint while another WorkerThread in PathCache is using the paint
which pointed to the same address of mFilteredPaint to generate bitmap.
As a result, it will generate a wrong bitmap for generateTexture in
PathCache. To fix it, do a copy of paint when creating PathTask.

App crashed by catch IndexOutOfBoundsException which raised
by check span range when select suggested string.The root
cause is that the editor will truncate the suggested string

Update the suggestion's real length after editor replace the
