- Added new class `CMFGSTBuffer` which can allocate memory internally or provide GStreamer allocated memory to Media Foundation. - Added `GstBufferPool` to limit allocation of output buffers used for rendering (memory will not be allocated for each buffer, but instead will be reused from pool). Limits are 3 min buffers and 6 max buffers. During testing 3 buffers was enough. - Changed `CoInitializeEx` to `COINIT_MULTITHREADED` as per Media Foundation requirements. - Added error handling for `ProcessOutput` in case of https://bugs.openjdk.org/browse/JDK-8329227. With error handling `MediaPlayer` fails nicely instead of silent hang.
