Message:

Debugging support for libusbvirt

Added methods debug and lib_debug to device structure to simplify
debugging. Each method gets as a parameter debug level describing
verbosity of the message and also message tag that allows filtering
based on message type (e.g. messages related to transactions, to
device requests etc.).
