cgminer: 4.3.4-1~getdeb1

  * New upstream version
    - Add support for 2 nonces per block in spond driver
    - Increase timeout on reset in cta driver to 5 seconds
    - Increase max diff on spondoolies driver slightly to be well below spi
    comms
    limitations
    - Use the active contents lock and safe list iteration within the linux
    usbfs
    code
    - Add Ruby Api Example
    - Automatic detect the small miners
    - Update default modules from 3 to 4
    - Fix the temp max. we should use currect max temp
    - add avalon2-cutoff options
    - Enable the cutofftemp to Avalon2. ignore longer coinbase and longer
    merkles
    stratum
    - Fix the diff value used on MM firmware
    - Mark pool as idle if stratum restart is failed
    - Add hacky workaround for double list removal race in libusb
    - Make the work given in benchmark mode deterministic on a per-device
    basis
    - Rework the benchmarking code to use a deterministic set of work items
    with a
    known number of diff share nonces at regular spaced intervals
    - minion - restrict nonce read result size to ioctl() limit
    - minion - must check temp when overheated
    - minion - idle chips that hit >100C until back to 80C
    - minion - report the chip/reg when aborting due to an invalid ioctl()
    size
    - minion - all freq in Mhz but only convert when used
    - minion - remove unused ioctl debug
    - minion - command queue is now larger
    - minion - check rolled in stale work cleanup
    - Work stats should be based on device_diff not work_difficulty since
    non-shares
    haven't been filtered out yet
    - Prevent a segfault when writing a config file containing 'rotate'
    option
    - minion - comment out HW debug message
    - minion - roll work to reduce CPU
    - minion - report init_freq in stats
    - api - howoldsec is only used for USB
    - minion - allow setting the frequency
    - minion - disable iostats by default since it slows down mining
    - minion - define frequency value table
    - minion - report temp/cores/freq and handle temp formatting
    - minion - item is undefined
    - Rationalise diffs stored in the work struct and document them to avoid
    further
    confusion
    - Add basic API stats for nfu drivers to see how many submits each chip
    returns
    - Add output direction for the EN0 pin on nfu driver
    - Support power management optimisations in newer nf* firmware
    - Support variable numbers of chips with NFU and BXM drivers
    - Identify number of chips in nanofury devices and change name
    accordingly
    - Rename nf1 driver to nfu in anticipation of support for more chips
    - Make hashfast reset counter rise on old instances when inheriting the
    value on
    new ones
