Created after hardware/audio.h with the following changes:
- names changed to satisfy HAL style guide;
- defined getter / setter methods for properties, and interfaces
for devices where needed;
- stream out callback changed to be used over RPC;
- 'dump' method is already defined by BBinder, so in HAL
interfaces it is replaced by 'debugDump'.
Note that audio data is currently transferred using byte buffer,
which is not effective due to memory copy and HwBinder transaction
involved. The transfer method will be changed to FastMessageQueue.

* changes:
graphics: add a default implementation to IMapper
graphics: add IMapper to complement IAllocator
graphics: add a default implementation to IAllocator
Add HAL definition for graphics buffer allocator
Initial version of the sound trigger HAL for TREBLE model.
Functionally equivalent to legacy HAL.

The default implementatoin is built on top of conventional gralloc1.
Test: make android.hardware.graphics.mapper.hallib

IMapper is loaded in-process and is defined in C++ instead of HIDL. To
guarantee binary compability, the interface is a struct of function
pointers instead of a class of pure virtual member functions. The
functions pointed to by the function pointers must also have C-linkage and
have all of their parameters PODs.
Implementations are expected to be installed to
/oem/lib/hw/android.hardware.graphics.mapper.hallib.so
/vendor/lib/hw/android.hardware.graphics.mapper.hallib.so
/system/lib/hw/android.hardware.graphics.mapper.hallib.so
(lib64 instead of lib for 64-bit implementations)
The loader will look for the symbol "HALLIB_FETCH_Interface" and use it to
fetch the interface.
Test: make android.hardware.graphics.mapper@2.0

The default implementatoin is built on top of conventional gralloc1.
This also adds a static library, libgralloc1-adapter. It is intended to
ease the porting of gralloc0 to gralloc1.
Test: booted to launcher, tested with YouTube and some games.

It differs from gralloc1.h in that
- buffer descriptors are created from a struct, BufferDescriptorInfo, to
reduce round trips
- testAllocate is a function of its own
- buffer allocation and export are two different steps
- reference counting and buffer mapping are moved to gralloc-mapper
- BAD_HANDLE is renamed to BAD_BUFFER
- GRALLOC1_CONSUMER_USAGE_FOREIGN_BUFFERS is removed
- CPU_{READ,WRITE}_OFTEN no longer implies CPU_{READ,WRITE}

Created after hardware/audio_effect.h with the following changes:
- names changed to satisfy HAL style guide;
- defined an interface per effect, an interface method
per command, and getter / setter methods for properties;
- retained methods for executing proprietary commands
and accessing proprietary properties, only to be used
for third-party software effects;
- HIDL vector type is used instead of count / array pairs;
- provider callback changed to be used over RPC;
- 'dump' is method is already defined by generated code.
Note that audio data is currently transferred using AudioBuffers,
which is not effective due to memory copy and HwBinder transaction
involved. The transfer method will be changed to FastMessageQueue.
