I've been doing some updates. It's working, some real scenario tests
are required but works with my tests. I've fixed an stupid issue where
I forgot to open the DB on the decoder pipe.

TODO:

- Code cleanup.
- More testing.
- Configuration must be improved. For example, in the current code
there is no easy way to access the configuration from everywhere. To
finish this first implementation faster I've added a method in the
XCodecCache class and its subclasses called new_uuid(). This is to
open a new cache using the same parameters but with a new UUID. If the
configuration system is improved we could remove this.
- DB prunning, ageing.
- Close the database when there is an stop event.
- etc.

Regards,
 Diego
