Stefan Kalkowski a145e6ad70 nic_bridge: transition to the new base API
* use Component::* instead of Server::*
* do not use old printf format anymore
* do not use old Genode::env()->heap() anymore
* avoid pointers where possible, and use references instead
* throw away the thread-safe variants of list and AVL tree,
  nic_bridge became single-threaded in the past
* introduce Ram_session_guard instead of Allocator_guard
