* sapi/include/confdefs.h: Add CONFIGURE_MESSAGE_BUFFER_MEMORY so there is less dependence on CONFIGURE_MEMORY_OVERHEAD. Do not arbitrarily add 1 to CONFIGURE_MEMORY_OVERHEAD so we do not waste a kilobyte for unused Workspace. Round the workspace required size to an 8 byte boundary instead of a 0x400 byte one. We may end up needing to add 8 bytes again to account for the alignment rounding.
