remove syncer?

[Wouter1]

The mSyncer is deprecated by Apple. Maybe we can find a different way to do this

I removed the syncer entirely. It all seems to work fine.

But IOSyncer.h is still there? The function that being used might just have been removed from the .h but still somewhere in IOSyncer (the system).

[Wouter1]

There is some code related to IOService.addNotification and a call in audioDevicePublished when a device is found. I will just try what happens if I throw it all out.

After removing the mSyncer and related code I got a kernel panic when turning off the device. This is the message

panic(cpu 6 caller 0xffffff800f64e7fa): "A kext releasing a(n) EMUUSBAudioDevice has corrupted the registry."@/SourceCache/xnu/xnu-2422.115.4/libkern/c++/OSObject.cpp:218

I found in #79 that the syncer must be somewhere still in the system. Maybe it's not public anymore or so?
