audio: Replace SDL_CreateAndBindAudioStream with SDL_OpenAudioDeviceStream.

Browse source 
This is meant to offer a simplified API for people that are either migrating
directly from SDL2 with minimal effort or just want to make noise without
any of the fancy new API features.

Users of this API can just deal with a single SDL_AudioStream as their only
object/handle into the audio subsystem.

They are still allowed to open multiple devices (or open the same device
multiple times), but cannot change stream bindings on logical devices opened
through this function.

Destroying the single audio stream will also close the logical device behind
the scenes.
