I note that latest mongoose 6.16 finally has a virtual ssl layer and appears to support mbedtls (polarssl) in addition to openssl.

I now think I should see if it works - as it gives us a way to support https without relying on the user having
pre-installed working openssl packages - we consistently run into problems with openssl on macos, and even
on linux there was trouble with preinstalled openssl packages and libraries.

With mbedtls, one will have to "git pull" and "make" it, but historically this causes much less trouble.

Also, with luck, mbedtls has better support for certificate expiration (I would really love to have openssl report an error
or a warning or at least some hint if I feed it an expired certificate) and (gasp!) certbot integration.

K.O.
