- Python 3 now supported.
- Bump boost version to 1.61 - one boost patch no longer needed.
- All checked with OpenBSD 5.9, except for the clang part, I left this
as-is for someone adventurous.
- Mention overriding resource limits, OpenBSD's default ulimit does not
suffice for building Bitcoin Core with gcc 4.9.3.
