ao_coreaudio: change license to LGPL All authors have agreed to the relicensing. The code was pretty much rewritten by Stefano Pigozzi. Since the rewrite happened incrementally, and seems to include refactored portions of older code, this relicensing was done on the pre-refactor code do. The original commit adding this AO (as ao_macosx.c) credits Timothy J. Wood as original author. He was asked and agreed to LGPL. It's not entirely sure from which project this code came from, but it's probably libao. In that project, Stanley Seibert made some changes to it (who as a major developer of libao was asked just to be sure), and also Ralph Giles and Ben Hines made two small changes. The latter were not asked, but none of their code survived anyway.

audio/out: make ao struct opaque We want to move the AO to its own thread. There's no technical reason for making the ao struct opaque to do this. But it helps us sleep at night, because we can control access to shared state better.

ao_coreaudio: refactor properties code Introduce some macros to deal with properties. These allow to work around the limitation of CoreAudio's API being `void **` based. The macros allow to keep their client's code DRY, by not asking size and other details which can be derived by the macro itself. I have no idea why Apple didn't design their API like this in the first place.

ao_coreaudio: fix compilation on OS X 10.7 Reverts one of the changes from 18777ecf. `kAudioObjectPropertyScopeOutput` was introduced in the 10.8 SDK while `kAudioDevicePropertyScopeOutput` was moved to `AudioHardwareDeprecated.h`. Since the deprecation is silent for now (no warnings), just use the old constant. Either way, they both evaluate to 'outp', and in the 10.8 SDK the deprecated constant is defined in terms of the non-deprecated one. Fixes #155
