Subject: Add option to disable async

Add no-async option to Configure that forces ASYNC_NULL.
Related to RT1979
An embedded system or replacement C library (e.g. musl or uClibc)
may not support the *context APIs that are needed for async operation.

Compiles with musl. Ran unit tests, async tests skipped as expected.
