0f215c5a33 graphics: add a default implementation to IMapper
The default implementatoin is built on top of conventional gralloc1.

Test: make android.hardware.graphics.mapper.hallib

9af67ec5f8 graphics: add IMapper to complement IAllocator
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

109571a22a graphics: add a default implementation to IAllocator
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.

e78aa1bd90 Add HAL definition for graphics buffer allocator
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}

Test: make android.hardware.graphics.allocator@2.0
