Bug#19575 MySQL-shared-5.0.21-0.glibc23 causes segfault in SSL_library_init 

 - Include prefix files that renames all public functions in yaSSLs
   OpenSSL API to ya<function_name>. They will otherwise conflict
   with OpenSSL functions if loaded by an application that uses OpenSSL
   as well as libmysqlclient with yaSSL support.
