Motivation:
ReferenceCountedOpenSslEngine is careful to lock access to `ssl`
almost everywhere (manually verified) *except* in the constructor.
Since `ssl` is non-final, it does not enjoy automatic thread safety
of the code that uses it. Specifically, that means netty tcnative
code is not thread safe.
Modifications:
Ensure that all ssl engine intialization and variables related to
it are properly synchronized by adding in the constructor.
Result:
Less noisy race detector.
Notes:
The specific racing threads are:
