Bug Fixes and Driver Improvements

A number of bugs have been fixed for this driver release. Below are brief notes on the significant fixes.

• Fixed bug in Hercules dscDASetSettings() which reset AD settings.
• Fixed bug in Diamond-MM dscADScanInt() under QNX which caused delays in ISR.
• Improved Quartz Measure Period function.
• Fixed bug in dscCancelOp() under Linux which could result in duplicate data in some cases.
• Improved Linux handling of delays caused by slow user interrupt functions
• Change to Diamond-MM-32-AT digital I/O behavior for functions dscDMM32DIOOutputByte() and dscDMM32DIOInputByte().
• Bug fix for dscCounterSetRate() to not attempt to set the internal clock if internal_clock is false.
