Comment 52 for bug 1797386

RE: perl openssl read/write|_all changes

OpenSSL 1.1.1 has enabled AUTO_RETRY by default and all non-application data records are retried by default. Thus this is effectively a no-change for higher level users as retries have moved further down the stack to libssl itself.

Upstream executes testmatrix across a wide array of openssl implementations, and perl releases, thus there is a degree of confidence in shipping upstream preferred change of api.

As a contingency, reverting the api changes and limiting context to cap at tls1.2 will be our path forward if we need to revert this upload.
