tonihei c63f3d92ba Remove ExoPlaybackException.TYPE_OUT_OF_MEMORY
Catching OOM errors is bad practise unless there is a specific known
cause that tried to allocate a large amount of memory. Without this
known cause with a large allocation, the source of the error is
likely somewhere else in the app and every random small further
allocation may lead to additional OOM errors (for example b/145134199).

We have three known causes in ExoPlayer:
 1. Source allocations based on unexpected values in streams. This is
    caught on the loader thread and reported as an
    UnexpectedLoaderException.
 2. Output buffer allocations by non-MediaCodec decoders. These are
    caught in SimpleDecoder on the decoder thread and reported as
    UnexpectedDecodeException.
 3. Input buffer allocations by non-MediaCodc decoders in their
    constructors. These are currently caught on a higher-level and
    reported as ExoPlaybackException.TYPE_OUT_OF_MEMORY.

For consistency and to prevent catching OOM errors without known cause
we can remove the generic TYPE_OUT_OF_MEMORY and catch the specific
exception where it occurs to report it as an
ExoPlaybackException.TYPE_RENDERER. This also has the added advantage
that the format metadata is added to the exception.
