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:

IndexOutOfBoundsException observed rarely in ProcessStats

Sometime IndexOutOfBoundsException is observed in ProcessStats
while allocating longs array. This could be due to synchronization.
This fix will return if array index is >= size.
