      Fix various platform-specific problems.
     @ configure.cmake
        Always check how to do pthread_once.
        Do it with '-Werror' if compiler supports it.
     @ extra/yassl/src/buffer.cpp
        Always include my_config.h first.
     @ extra/yassl/src/yassl_int.cpp
        Include <pthread.h> as early as possible (symbol conflicts on freebsd).
        The callbacks should be C functions (warnings on solaris)
        Re-setting yASSL::session_created is not portable (solaris)
     @ unittest/gunit/yassl/CMakeLists.txt
        The unit tests needs libsocket (solaris)
     @ unittest/gunit/yassl/yassl-t.cc
        Include <pthread.h> as early as possible 
        (symbol conflicts on freebsd, missing symbols on solaris).
