Patch from Ben Kaduk: Conditionalise support for MD4, MD5.
Added support for linking libraries in /usr/local/lib64 for some flavours
of Linux like RH Tikanga.
Fixes to X509_check_host, X509_check_ip, SSL_CTX_set_alpn_protos, and
SSL_set_alpn_protos so they will compile on MSVC and AIX cc. Thanks to
AGRUNDMA.
Fixed typos in documentation for X509_NAME_new and X509_NAME_hash
incorrect version 1.45 instead of 1.55 given.
Version number in META.yml is now quoted per request from Satoshi Yagi.
