SDL2 for Windows and OSX: rebuilt from SDL hg-11427:381449ca1cd2 :

- Mainly includes a few Mac OS X fixes since rev. 11413.

- The Windows builds exclude the new wasapi audio feature, because it
  keeps sending AUDIO_F32LSB in the obtained.format for me.

- The x64 part of the OSX builds does include the new Vulkan support
 (I build against 10.8 SDK to target 10.6+, but I hacked && butchered
  Metal.framework headers from 10.11 SDK to play nice with 10.8 SDK.)
