 Version 3.4.0 - 21st August 2013
 - Use stack data for HW error% in avalon stats.
 - Add avalon HW error% to stats and only show BTB variables if avalon is a BTB.
 - Check for cnx_needed on each loop through wait_lp_current.
 - Return positive for cnx_needed when no_work is true.
 - Stratum is used more often so test for it first.
 - Reorder support names alphabetically.
 - Only display the no pool work message once if there are multiple waiters in
 hash_pop
 - Provide a message and set a bool when no work is available from any pools and
 when it resumes again.
 - We don't want to continue into the hash_pop function if the getq is frozen.
 - Only report threads in and out in queued work devices across a get work since
 the rest happens asynchronously and the get work is what the device might be
 waiting on.
 - Thread reportin and out can be static non inline.
 - usbutils cps sleep_estimate is not an underestimate
 - usbutils add cps stats estimates
 - Provide cgtimer_sub helper functions.
 - Provide cgtimer_to_ms helper functions.
 - Rename cgsleep_prepare_r as cgtimer_time to get time in cgtimer_t format and
 call cgsleep_prepare_r as a macro for cgtimer_time
 - Use the reentrant cgsleep functions for usecps in usbutils.
 - TimeBeginPeriod and TimeEndPeriod do not add significant overhead when run the
 entire time for cgminer so avoid trying to maintain balanced numbers of them for
 specific time calls to simplify code.
 - Replace all references to the old n*sleep functions with the equivalent
 cgsleep_*s replacements.
 - timeGetTime uses huge resources on windows so revert to using timevals for its
 implementation of cgtimer_t
 - Quotient/remainder error in ms division.
 - Only grab a queued work item if we successfully grab the lock to submit work
 in bflsc_send_work
 - BTB get version from Firmware
 - Carve out the unused portions of sha2 implementation.
 - Import Aaron D. Gifford's fast sha256 implementation.
 - Increase the que_low watermarks on BFLSC for they are too low to keep the
 device busy on scanwork loops.
 - Provide cgtimer_to_timeval helper functions.
 - Provide a timeval_to_cgtime helper function to reuse values.
 - Check for thr->work_restart in restart_wait.
 - We should be using que_low to decrease scan sleep time in bflsc.
 - Prepare sleep time on bflsc if no dev needs work yet to avoid busy waiting.
 - Simplify cgsleep code for windows by using a typedef for cgtimer_t that
 resolves to clock resolution, using that internally.
 - On windows use the higher accuracy timegettime function to really get 1ms
 clock and timer accuracy.
 - Use the cgsleep reentrant function to sleep for bflsc between read results to
 account for time taken to perform reads.
 - Use 100ms delay between checking for results on all bflsc devices as the
 buffering of results mean checking more frequently just wastes CPU and causes
 more lock contention for only marginally better latencies.
 - Fix missed endtimeperiod in overrun timer on windows.
 - Make cgsleep_us_r take an int64_t for us.
 - Make the cgsleep functions build on windows.
 - Use the cgsleep reentrant function in avalon_send_task.
 - Use the reentrant cgsleep functions within the avalon_send_tasks function.
 - Set high resolution timing on windows within the cgsleep functions.
 - Use the reentrant cgsleep function to time sleeps on reading from avalon.
 - Provide reentrant versions of cgsleep functions to allow start time to be set
 separately from the beginning of the actual sleep, allowing scheduling delays to
 be counted in the sleep.
 - Make the nmsleep and nusleep functions use the new cgsleep functions
 internally till functions are migrated to the new cgsleep API.
 - Add a ms_to_timespec helper function, and create a cgsleep_ms function that
 uses absolute timers with clock_nanosleep to avoid overruns.
 - Add rt lib linkage to enable use of clock_nanosleep functions with older
 glibc.
 - Add necessary time header include to avalon driver.
 - Do a sleep of the full duration it would take to do all the work using
 clock_nanosleep in avalon_send_tasks to avoid sleep overruns before polling to
 see if it's ready.
 - Add a timeraddspec helper function.
 - Provide a us_to_timespec helper function.
 - Use the us_to_timeval helper function in the avalon driver.
 - Provide a us_to_timeval helper function.
 - Use timeval_to_spec helper in avalon driver.
 - Add helper functions to convert timespec to timeval and vice versa.
 - simplifying buffer full check
 - forking bitburner write thread function
 - making sure original Avalon is unaffected by BitBurner changes
 - changes to queueing strategy for BitBurner boards
 - Do not poll in avalon_get_results without sleeping if we have finished parsing
 a full result.
 - Add c to ambient temperature display for avalon driver.
 - BTB allow up to 1400mV as per firmware limits
 - avalon for timeout allow d='calculate it' and fix uninitialised
 - Use cloned work when finding avalon results since another thread can discard
 the work item while it's in use.
 - Provide a variant of find_work_bymidstate that returns a clone of the found
 work.
 Version 3.3.4 - 14th August 2013
 - API/miner.php add some % fields
