 Version 3.7.1 - 5th November 2013
 - Return ETIMEDOUT regardless if we fail in cgsem_mswait since we may be waiting
 on it on shutdown and the return response is harmless.
 - Clean up completely on avalon shutdown.
 - Use cgsem timed waits in avalon driver to not miss any queued wake ups to
 account for async messages coming during a flush work.
 - Statline before is too long on icarus that doesn't have monitoring.
 - Different windows+usb combinations respond with varying levels of reliability
 wrt timeouts so use a nominal extra 40ms before cancelling transfers that fail
 to time out on their own.
 - Do all hotplug_process under the write mining_thr_lock
 - Fix for opt_worktime on big endian machines.
 - Correct set_blockdiff for big endian machines.
 - Make sure cgpu exists in the restart threads loop in cases of hotplug etc.
 - Treat usb write timeout errors as unrecoverable.
 - Transfer errors are filtered out in usbutils now so no need to look for them
 in NODEV checks.
 - Remove now unused entries from struct cg_usb_device
 - Do not double up with checking for end of timeout measurements in usb
 read/write.
 - Do get_work in fill_queue without holding other locks.
 - Initialise usb after all the locks and conditionals are initialised.
 - Use only a trylock in flush queue to prevent deadlocks.
 - Add a wr_trylock wrapper for pthread rw lock write trylock.
 - Scale diff for scrypt when testing for block solves.
 - Fix for non curses build.
 Version 3.7.0 - 4th November 2013
 - Use WRITEIOERR macro check for all usb writes.
