Enrico Weigelt, metux IT consult f790bae8dc Xnamespace: initial config loader
This loads the configuration (simple text file) passed via command line.
For now just supporting static configuration, that's loaded on server
startup.

Enrico Weigelt, metux IT consult 5f619d862d os: use calloc() instead of malloc()
Using calloc() instead of malloc() as preventive measure, so there
never can be any hidden bugs or leaks due uninitialized memory.

The extra cost of using this compiler intrinsic should be practically
impossible to measure - in many cases a good compiler can even deduce
if certain areas really don't need to be zero'd (because they're written
to right after allocation) and create more efficient machine code.

The code pathes in question are pretty cold anyways, so it's probably
not worth even thinking about potential extra runtime costs.
