HIDL templated destructorandroid-o-mr1-iot-release-1.0.2
This change implements a simple template function to explicitly destruct
objects in HIDL. This is particularly useful in the context of HIDL safe
unions, where non-primitive objects are constructed using the placement
new operator.
Bug: n/a
Test: Ran make
