    Use channel_t in cpuworker.c
    
    Note: this is a squashed commit; see branch bug6465_rebased_v2 of user/andrea/tor.git for full history of the following 2 commits:
    
    Use channel_t in cpuworker.c
    Fix bug in channel_t usage in cpuworker.c that was killing relaying on channel_t-ized Tor.  The tags passed to the worker now have a channel ID, not a connection ID.
