Most of the changes here reduce the amount of locking involved

This makes more use of qemu_log_lock/unlock around code blocks,
which both keeps the output together in the face of threads and
also plays the rcu_read_lock game only once for the block.
Finally, add a -d tid option to open per-thread logfiles.
This can be extremely helpful in debugging user-only threads.
Gah. I didn't mean to write 'PULL' here, just PATCH.
