Project: ncnn support AVX only CPU

项目：ncnn 支持 AVX only CPU

Brief Explanation: There are some processors without AVX2 and FMA capability. In such circumstance, ncnn fallbacks to SSE2 optimized path now.

In addition, testing and documentation is a MUST to keep maintainability.

Project: ncnn better android vulkan camera frame importing and rendering

项目：ncnn 更好的 android vulkan 相机帧导入和渲染

Brief Explanation: GPU is a suitable device for image processing and machine learning workflow. For realtime processing, we shall try best to eliminate all possible overheads involing the inefficient CPU-GPU data copy. VK_ANDROID_external_memory_android_hardware_buffer is a new vulkan extension that allows us to access the on-device camera captured frame pixels on Android platform. However, it is quite hard to write raw vulkan code directly for utilizing it. We propose a project to emerge an easy to use high-level api for Android vulkan and ncnn interop. In addition, testing and documentation is a MUST to keep maintainability.
