Added some preliminary configure and config.h stuff for
SSE/SSE2 for Stanislav. Also, some method prototypes and skeletal functions in access.cc for read/write double quadword features. Also cleaned up one warning in protect_ctrl.cc for non-64 bit compiles. There was an unused variable, only used for 64-bit.
