step 1: metaserver

The first step into improving csync2 is having a metadata server. Actually the only problem with csync2 is the metadata management. The locking and such. It hurts. So how does that look like:

The processes:

csi: csync2 inetd service

This one handles incoming connections. It's intended only to receive files.

csc: csync2 hint checker

This one parses al hints, and turns them into dirties, or not.

csh: csync2 hint insert.

Dumb inserting of hints.

csu: csync2 updates to external servers, handles the dirty queues
