- minion - clean up statline

- Display the base clockrate for hfa devices with a different name to per die
clockrates to be able to easily distinguish them.

it being invalid.

their sizes may change.

shutdown as the imitated reinit to allow it to hotplug again.
- Reset opt hfa dfu boot after it's used.
- Comment out windows only transfer on hfa startup.
- Clean up structures unused in case of all failures in hfa detect common
- Clear all structures should we fail to hfa reset on adjusting clock on a
hotplug.
- Set master and copy cgpu hash clock rate for hfa when dropping it on a
restart.
- Set the master hfa clock speed to lower when shutting down a copy.
- Do a clear readbuf on any hfa reset in case the device has not yet cleanly
shut down.
- Increase hfa fanspeed slightly more when it's rising in the optimal range than
falling.
- Always decrease hfa clock speed on a running shutdown and don't try sending an
init frame since it will be dropped regardless.
- Match hfa devices to old ones based on OP_NAME values before serial numbers if
possible.
- Read off the OP_NAME if it exists and is supported on hfa devices, setting it
to the device serial number or a timestamp if it is invalid.
- Updated hf protocol
- Check for an amount along with no error in hfa clear readbuf
- Hfa clear readbuf can return a nonsense amount when there's a return error so
ignore the amount.
- Running resets always cause a shutdown on hfa meaning the device will
disappear with modern firmware so always kill off the threads to allow
re-hotplugging.
- Reset the hfa hash clock rate to the old one if we find an old instance, only
setting the device id in hfa_prepare
- Keep the device_id on the original zombie thread for HFA in case of further
resets.
- Break out of hfa inherit if there is no device data.
- Inherit the hfa zombie instance after the device id has been allocated.
- The list_for_each_cgpu macro will dereference when there are no mining threads
yet.
- Make hfa hotplug inherit some parameters from a previous instance if the
serial number exists and is matching, avoiding dropping the clock on all
devices.

further usb comms attempts.

- Update the per die hash clock data on a running reset on hfa devices.
- Set the per die clock on hfa to the known starting base clock instead of our
requested clock rate.
- Hfa device failure can be detected within 15 seconds so we should try
restarting it sooner to avoid tripping the device's own watchdog.

- Send a work restart with every shutdown message to hfa devices to clear any
work that might be stale on the next restart.

consideration when calculating the highest temperature as well as the dies.

info
- Add hashfast fanspeed% to statline display.
- Move driver statline padding to cgminer.c, expanding width of maximum
displayable statistics and window width to add more info.
- Prune old stratum shares that we've seen no response for over 2 minutes to
avoid memory leaks for pools that don't respond about some shares.

- Break out of linked list loop in remove_in_use in case we've gone over the
whole list.
- Check for hfa invalid hash clockrate after other error messages.
- Detect non-responsive icarus devices and attempt a usb reset before killing
them after 2 minutes of no hashes.
- Detect non-responsive bitfury devices and try a usb reset on them before
killing their instances off after 2 minutes of no activity.

- Prevent recursive loop in __is_in_use linked list walking.

- Use a bool in struct cgpu to know when a usb device has been blacklisted,
avoiding blacklisting it more than once.

Version 3.12.2 - 8th February 2014
- Adjust antminer U1 timing according to command line frequency set, fixing the
need for icarus timing on the command line.
- Read pipe errors that don't clear are worth attempting to reset the usb.

errors now and they're of dubious value."

miss a wakeup.
Version 3.12.1 - 7th February 2014

- Add support for ANU overclocking.
- Increase hfa fanspeed by more if we're rising in temp above the target than if
the temp is staying the same.
- Add debug output when get_work() is blocked for an extended period and add
grace time to the device's last valid work to prevent false positives for device
failure.
- Issue a shutdown prior to a reset command for hfa devices and lock access to
reads awaiting the response if the device is already running.
- Do not register as successful a hfa init sequence that reports the clockrate
as zero.

- Widen lines in top menu to fit extra large share values.
- Only show one decimal place if pool diff is not an integer.

errors.
