QSslCertificate - make lazy initialisation thread safe
QSslCertificate can be copied around into multiple threads,
without detaching. For example, the https worker threads inside
QNetworkAccessManager.
There are const methods, which lazily initialise members of
the private class without detaching (i.e. caching results of
expensive function calls)
These functions now lock the d pointer using QMutexPool to
avoid concurrency related crashes.
autotest crashes 20% of the time in release builds without
the fix, passes 100 times in a row with the fix.
Task-number: QTBUG-20452
Change-Id: I64a01af8159216f2dd6215a08669890f6c029ca8
