Actually for quite many config items it makes sense to use cbdata.

* Main pointer linked in Config
* Other modules uses a cbdata reference while referring to that
configuration entry.
* When the configuration is freed, cbdataFree() is used, making all
references !cbdataValid().

A good example are peers.

A common way to do it is to use stat(), and reread the file it if has
another modification time or size than the last time it was read and the
current modification time is sufficiently old (lets say 10 seconds).

stat() should be fairly portable (100% within the UNIX world at least),
but is not part of standard-C.
