Pull request description:

  This removes [BIP70](https://github.com/bitcoin/bips/blob/master/bip-0070.mediawiki) support. It also removes OpenSSL linking from Qt and building OpenSSLs `lib_ssl` in depends, as well as SSL lib detection from the build system. It's something that I'd optimistically like to do for `0.20.0`.
