Support shared av memory handle in Tuner JNI
In the MediaEvent of AV filters, the AV memory handle is mapped/unmapped on each event.
If the vendor allocates a persistent memory block, and use MediaEvent.offset to access the data,
the mapping change is unnecessary.
To improve this, a new API to get shared AV Memory is introduced in
Tuner HAL 1.1.
Tuner JNI queries the sharedAvMemory Handle when the media filter is
opened. It builds up linear block through either shared or independent
memory block by checking the memory handle fd number.
