* This just adds the infrastructure,
* but we does not implement it yet!
*
* Currently it only prevents that
* nodes with a different version numbers
* cannot run at the same time.
*
* Each node checks at startup, if the version
* matches the version of all other nodes.
* And it exits if the version does not match
* to avoid corruption.
*
* While it would be possible to add versioning
* to each of our internal databases it is easier
* use a dedicated database "smbXsrv_version_global.tdb"
* to hold the global version information.
*
* This removes extra complexity from the individual
* databases and allows that we add/remove databases
* or use different indexing keys.
