svn diff for www/serf
The current LibreSSL patch for www/serf just kills the OpenSSL 1.1 API completely.
LibreSSL 2.7 (2.8 is the only available version in ports) added most of the OpenSSL 1.1 API.
Attached patch switches to OpenSSL 1.1 API for LibreSSL and fixes the one missing call (OpenSSL_malloc_init) in LibreSSL.
