One thing I remembered after sleeping on it is that we can split the
patch into two parts: the refactoring pieces and the addition of the
options for libpq.  The previous review mostly impacts the libpq part,
and the split is straight-forward, so attached is a patch for only the
refactoring pieces with some fixes and tweaks.  I have tested it with
and without OpenSSL, using 1.0.2 and 1.1.0 on Linux and Windows
(MSVC).  Those tests have allowed me to find an error in the previous
patch that I missed: the new files openssl.h and protocol_openssl.c
still declared SSL_CTX_set_min/max_proto_version as static functions,
so compilation was broken when trying to use OpenSSL <= 1.0.2.

If that looks fine, I would like to get that part committed first.
Daniel, any thoughts?
