TS-2271: Support plugins which use libraries which create threads and use
OpenSSL
This pair of patches implements changes to support TS-2271
(https://issues.apache.org/jira/browse/TS-2271).
* OpenSSL init + callbacks are changed to use raw pthread functions, so
that they work from threads which were not created using the ATS thread API
functions.
* TSHttpTxnReenable does not segfault when it's called from an unexpected
thread (not created by ATS thread API functions).
These changes are helpful in case a plugin utilizes a third-party library,
which in turn creates pthreads on its own, and ends up calling
TSHttpTxnReenable from a thread created by the third-party library.
