[Mesa-dev] [PATCH 01/23] vulkan: Import vk_android_native_buffer.h

[Chad Versace]

Just as Mesa imports the Khronos Vulkan headers, it should import this
Android-private Vulkan header too. This guarantees that Mesa will
continue to build even when upstream Android breaks header
compatibility.

This header is only for *implementers* of Vulkan, not for consumers of
Vulkan.

Imported from tag 'android-7.1.1_r28' in aosp/frameworks/native.
