Cameron Gutman a6003f6bff Remove MediaTek decoders from the decoders that need bitstream restrictions. The correct fix was to lower level_idc to reduce the required buffering. On newer MediaTek chipsets, sending bitstream restrictions actually slows down decoding by a factor of 3.

AndroidCpuDecoderRenderer.java

Use monotonic system time for rendering timestamps. This is required now in Android 6.0 since these timestamps are propagated to the codec.

ConfigurableDecoderRenderer.java

Use direct submit decoding for MediaCodec. Based on my profiling of a few devices, dequeueInputBuffer and queueInputBuffer don't take much time anyway. It allows us to stop our semi-busy looping which saves power. The depacketizer can avoid expensive synchronization and additional context switching which costs time and CPU cycles.
