  Support SDL audio devices that require float32 samples.

Fixes missing audio when playing on Windows with SDL 2.0.7, which started
using WASAPI, which demands floating point audio.

  Log Message:
  -----------
  sdl_snd.c should just initialize SDL audio without checking SDL_WasInit().

In SDL2, the initialized subsystems are referenced counted, so it's safe to
initialize them twice, and it makes the SDL_QuitSubSystem during our shutdown
correctly decrement the count. Before (as a probably-harmless bug), it would
not increment the refcount if the subsystem was already initialized, causing
problems when it decremented it later.

  There's no need to SDL_PauseAudio(1) before calling SDL_CloseAudio().

  -----------
  Added audio capture support to SDL backend.

This lets you speak through VoIP when not using OpenAL. Previously you could
listen but not speak.

  Log Message:
  -----------
  Use the SDL2 audio device interface instead of the legacy 1.2 API.

This is a little bit of future-proofing, but also gives us a little more
flexibility in general; now we can add in the cvars to open a specific
device, etc, that the OpenAL codepath does.
