Remove the callback indirection.
v2:
* switch to unsigned int and use min()

The maximum and default levels do not change and can be defined
directly. The set_level callback was a temporary solution and will be
removed.

The set_level callbacks do not do anything special and can be replaced
by a helper that uses the levels defined in the tables.
