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.


client/Makefile.am:
  Remove $yassl_includes
  ...and one "suspicious line"
config/ac-macros/yassl.m4:
  Remove yassl_includes as they are the same as "normal" include
extra/yassl/include/openssl/crypto.h:
  Add include file "prefix_crypto.h" to rename SSL_* functions to yaSSL_*
extra/yassl/include/openssl/ssl.h:
  Add include file "prefix_crypto.h" to rename SSL_* functions to yaSSL_*
libmysql/Makefile.am:
  Remove yassl_includes
libmysql_r/Makefile.am:
  Remove yassl_includes
libmysqld/Makefile.am:
  Remove yassl_includes
  And one suspicious line
libmysqld/examples/Makefile.am:
  Remove yassl_includes
server-tools/instance-manager/Makefile.am:
  Remove yassl_includes
sql/Makefile.am:
  Remove yassl_includes
tools/Makefile.am:
  Add link with yaSSL libs
vio/Makefile.am:
  Remove yassl_includes
extra/yassl/include/openssl/generate_prefix_files.pl:
  Add utility script to parse the header files to generate the prefix_* files that renames yaSSL SSL_* functions
extra/yassl/include/openssl/prefix_crypto.h:
  Add prefix file for crypto.h
extra/yassl/include/openssl/prefix_ssl.h:
  Add prefix file for ssl.h
