This change implements direct report for accel, gyro and mag at normal and fast rate level. It supports ashmem shared memory. The direct report and traditional sensor subscription are still tangled up in this implementation. Bug: 30985702 Bug: 33588372 Test: tested via demo app Change-Id: Idc4f626dfe624558718c1b04f16898a0ea247e62
