Charles Strahan af0c3bde27 macosx: track system default output/input device 
module-coreaudio-detect creates one PulseAudio sink per CoreAudio device
and pins the default to whichever sink was last set. As a result,
changes to macOS's System Settings > Sound output (and hot-plug events
that flip the default) were not reflected in PulseAudio, so streams
played to the daemon's default sink kept routing to a stale device.

Register property listeners on kAudioHardwarePropertyDefaultOutputDevice
and kAudioHardwarePropertyDefaultInputDevice. On each change, resolve
the current CoreAudio default to the matching PulseAudio sink/source
and drive core->policy_default_sink/source via
pa_core_set_policy_default_sink/source. A user-set configured default
still takes precedence, matching the policy/configured layering used
by module-switch-on-connect.

CoreAudio notifications are multiplexed over the existing self-pipe
with an event-type byte so the main thread can dispatch each event
type distinctly. At init we sync once against the current CoreAudio
default, and PA_CORE_HOOK_SINK_PUT / PA_CORE_HOOK_SOURCE_PUT hooks
re-apply when a device module's sink appears after a default-change
notification has already arrived (hot-plug race).

A new follow_system_default=<bool> modarg (default true) disables
the behavior for anyone who prefers the old pinned semantics.
