Critical interlocking bug in ASYNC AsyncAudioReader about svxlink HOT 1 CLOSED

The Async library is not written to be threadsafe so it can only be used safely from one thread. Threads should only be used in special cases where the asynchronous, or event based, mechanism is not possible to use. Such valid cases include: thirdparty libraries that only support a blocking API paradigm, muticore requirements, latency requirements.

The standard way to solve threaded use cases in SvxLink is to put the minimum amount of code that need to be in its own thread and then use a threadsafe mechanism to communicate data between the threads. An approach using a threadsafe FIFO to read samples from an RTL dongle can be seen in RtlUsb.cpp.

I'll close this issue since it's not a bug in Async but rather an API violation.
