nvdec,nvenc: Port to dynamic library loading ... and put them into new nvcodec plugin. * nvcodec plugin Now each nvenc and nvdec element is moved to be a part of nvcodec plugin for better interoperability. Additionally, cuda runtime API header dependencies (i.e., cuda_runtime_api.h and cuda_gl_interop.h) are removed. Note that cuda runtime APIs have prefix "cuda". Since 1.16 release with Windows support, only "cuda.h" and "cudaGL.h" dependent symbols have been used except for some defined types. However, those types could be replaced with other types which were defined by "cuda.h". * dynamic library loading CUDA library will be opened with g_module_open() instead of build-time linking. On Windows, nvcuda.dll is installed to system path by CUDA Toolkit installer, and on *nix, user should ensure that libcuda.so.1 can be loadable (i.e., via LD_LIBRARY_PATH or default dlopen path) Therefore, NVIDIA_VIDEO_CODEC_SDK_PATH env build time dependency for Windows is removed.

nvcodec: cuda.h only needs glib.h, not gst.h Just a nitpick. Also, force the compiler to use our stub header instead of searching for it in the include paths.

nvcodec: Fix crash on 32-bit Windows We weren't using the correct calling convention when calling CUDA and CUVID APIs. `CUDAAPI` is `__stdcall` on Windows. This was working fine on x64 because `__stdcall` is ignored and there's no special calling convention. However, on x86, we need to use `__stdcall`.

nvcodec: Fix crash on 32-bit Windows We weren't using the correct calling convention when calling CUDA and CUVID APIs. `CUDAAPI` is `__stdcall` on Windows. This was working fine on x64 because `__stdcall` is ignored and there's no special calling convention. However, on x86, we need to use `__stdcall`.

nvdec,nvenc: Port to dynamic library loading ... and put them into new nvcodec plugin. * nvcodec plugin Now each nvenc and nvdec element is moved to be a part of nvcodec plugin for better interoperability. Additionally, cuda runtime API header dependencies (i.e., cuda_runtime_api.h and cuda_gl_interop.h) are removed. Note that cuda runtime APIs have prefix "cuda". Since 1.16 release with Windows support, only "cuda.h" and "cudaGL.h" dependent symbols have been used except for some defined types. However, those types could be replaced with other types which were defined by "cuda.h". * dynamic library loading CUDA library will be opened with g_module_open() instead of build-time linking. On Windows, nvcuda.dll is installed to system path by CUDA Toolkit installer, and on *nix, user should ensure that libcuda.so.1 can be loadable (i.e., via LD_LIBRARY_PATH or default dlopen path) Therefore, NVIDIA_VIDEO_CODEC_SDK_PATH env build time dependency for Windows is removed.

nvdec: Don't use default CUDA stream Async CUDA operation with default stream (NULL CUstream) is not much beneficial than blocking operation since all CUDA operations which belong to the CUDA context will be synchronized with the default stream's operation. Note that CUDA stream will share all resources of the corresponding CUDA context but which can help parallel operation similar to the relation between thread and process

nvdec: Make OpenGL dependency optional By adding system memory support for nvdec, both en/decoder in the nvcodec plugin are able to be usable regardless of OpenGL dependency. Besides, the direct use of system memory might have less overhead than OpenGL memory depending on use cases. (e.g., transcoding using S/W encoder)
