Add description to hfa hash clock command.
Convert the hfa hashmeter to one based on successful share return and display the raw and calculated hash totals in the API.
Merge branch 'master' of github.com:ckolivas/cgminer
No point casting a double to a uint64
Test valid nonces in the hashfast driver allowing us to check against the target when trying to submit them.
Only count 2/3 of the accumulated hashes on each pass through the hfa scan work loop to smooth out displayed hashrate.
Count share based hashes in the hfa driver with the device diff to get more frequent updates.
Store when the last getwork was retrieved and display it in the API summary.
Reset hfa device if no valid hashes are seen for 1 minute from the last work.
Merge pull request #538 from kanoi/master

bab additions
Add throttling control to hfa driver, configurable at command line, nominally set to 85 degrees.
Avoid calling applog from within hfa statline before to avoid a deadlock.
Put a sanity check on the measured temperature in the hfa driver for obviously wrong values.
Decrease the hfa clock rate if it is overclocked and we have had to try resetting it.
Set the global hfa hash clock rate to equal the lowest if we are lowering it for a device reset since it may be re-hotplugged after failing reset.
Support the variable HFA naming throughout the driver notices.
Add hashfast documentation to ASIC README
Bump version to 3.11.0
