Well, it turns out that Mongoose also has an OpenSSL library
abstraction layer as an alternative to MBEDTLS, and wolfSSL has an
OpenSSL compatibility layer.  I have verified that we can plug the two
together without bloodshed.  I've made a mongoose-wolfssl branch with
this change implemented, but I have not tested it thoroughly.  I can
run server v2 and make connections to it through the app and the
server -- that uses SSL now, right?

I have also not done anything to reduce or remove MBEDTLS yet.  I
don't know if there are other dependencies.

Please check it out.
