GraphicProducerWrapper may return false transact status

GraphicProducerWrapper(GPW) changed how the methods of
BpGraphicBufferProducer(BpGBP) are executed.
First, "fake" BpGBP is created. Its remote is GPW. The GPW has
wrapped the real BpGBP.
All the method calls to the fake BpGPB will be intercepted by
the GPW inside it when the methods run into remote()->transact().
Then the GPW will invoke the transact() of the real BpGBP. And
Everything runs well except that the GPW forgets to store the
transact status and always return NO_ERROR to the fake BpGBP.

It would be disastrous if the binder call of the IGBP failed and
the out parameter "reply" of transact() was in unkown state.
E.g. the queueBuffer() in the fake BpGBP will try to operate on
the "reply". This will crash the SurfaceFlinger.

libui: fix passing Fence object over binder

The Fence object was writing a size_t into the binder buffer
in flatten, which changes size if the producer and consumer
are running in a 32-bit and a 64-bit process.  Use a uint32_t
instead.

egl: Fix debug flag for SW composition in Surfaceflinger

The debug.sf.hw property makes it possible to force Surfaceflinger
composition in SW by making it choose a slow EGL config. This feature
was broken in JB, which always loads only the HW renderer.
This change fixes it by loading the SW renderer when Surfaceflinger is
started while the debug property is set to 0.
