Three wrappers in this file: OPENSSL_strncasecmp, OPENSSL_strcasecmp,

and OPENSSL_memcmp.

All modern systems have strncasecmp.  No need to rewrite it.

Same with memcmp, call the system one!  It is more likely to be hot
in the icache, and is specifically optimized for the platform.  I
thought these OpenSSL people cared about performance?
