olly 2c7473dc05 Clean up logic for determining whether DRM reconfig needs codec re-init
1. Move logic to decide to re-initialize the codec rather than using
   MediaCodec.setMediaDrmSession if (a) PlayReady is in use, and (b)
   the new session is still provisioning. This would previously have
   happened asynchronously after an input format change, after the
   decoder has subsequently been flushed. After this change the logic
   executes synchronously when the input format changes. This helps
   with the ref'd bug, since we want to propagate reasons for codec
   re-initialization through inputFormatChanged events.
2. Whilst moving the logic for re-initialization if PlayReady is
   being used, I fixed a bug that would occur when switching from
   [PlayReady --> non-PlayReady]. Re-use doesn't work in this case.
   The old logic only checked for the [Something --> PlayReady] case.
3. Remove pointless codec flush if updating the DRM session having
   not queued anything to the codec.
