ao_coreaudio: move channel mapping code to a separate file Move all of the channel map retrieval/negotiation code to a separate file. This will (probably) be helpful when extending ao_coreaudio_exclusive.c. Nothing else changes, other than some minor cosmetics and renaming, and changing some details for decoupling it from the ao_coreaudio.c internals.

ao_coreaudio_chmap: change license to LGPL While the situation is not really clear for the other rewritten coreaudio code, it's very clear for the channel mapping code. It was all written by us. (MPlayer doesn't even have any channel map handling.)

ao_coreaudio_exclusive: deal with devices return different channel count If the device returns an unexpected number of channels instead of the requested count on init, don't immediately error out. Instead, look if there's a channel map with the given number of channels. If there isn't, still error out, because we don't want to guess the channel layout.
