This *must* be replaced by a real luid with a upcoming luidgen tool ASAP,
luids starting with zeros are invalid. For the time until this luidgen tool
is not ready we just leave it this way. Later it will be changed to give a
compile error.
uuid's are somewhat standardized, we use our uid's slightly differently,
so change the name not to be confused with standards.
* Small fix for luid generation
* build a 'luidgen' tool which will be used by the interface gen later
* add emacs vars
* include the luidgen tool in automake
