cgminer: 4.8.0-1~getdeb1

  * New upstream version
    - Allow forcing of building driver combinations with --enable-forcecombo
    - Put spaces between name and id in avalon2 and icarus
    - Relax detection of a failing ava2 to more than 1 minute and perform the
    test after polling for results
    - Cap maximum diff on ava2 in order to still get shares
    - Put space between device name and id to prevent device names with
    numbers in them confusing the display
    - USB write errors are always fatal so they should be treated as such on
    ava2
    - Issue a usb reset for ava2 that is not returning valid shares and then
    drop it if it persists for over a minute
    - Process share results without a result value
    - Damp out hashrate displayed for antminer USBs
    - Add voltage and speed where relevant to antminer USBs
    - Don't estimate time on any antminer usb during a timeout
    - Return icarus nonce ok only when the nonce size matches the device or
    more
    - Don't discard old workids until we cycle back to them on antusb and
    look for more nonces in the buffer
    - Adjust ant usb timing for queued work
    - Use a cyclical list for the ant queued work
    - Mask and limit workid for antusb and don't clear buffer
    - Check the nonce on the worked item, not the submitted work
    - Skip over unfinished work that we can't free in ant usb
    - Use a workid and array if possible for the small ant usb work queue
    - Create an array for antworks for antminer usb devices
    - On U3 calculate hashrate purely on shares, not timeouts
    - Add switches for AU3
    - Adjust icarus wait timeout according to device
    - Differentiate U3 from U1/2 as a separate driver with different
    parameters and adjust timing accordingly
    - Skip ANUs detected in rock detect
    - Try U3 after trying other icarus options
    - Add rudimentary ANU voltage setting support for U3
    - Fix ignoring unprefixed v6 address in api allow list
    - Fix minor typos in Spondoolies SP10 and SP30 drivers
    - Implement a basic rock_flush function to discard the base work we are
    rolling work from.
    - Task_no for rockminer from the nonce bin should simply be masked
    - Change rbox default correction times to 5 in a revised frequency order
    - Change default frequency on T1 to 330
    - Reinstate last received check and resend in rockminer, being more
    lenient at 2 seconds to allow for dither errors at 1
    - Roll work for the rbox when possible
