* 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.
