GitLab

- Uses the asynchronous reading mode and the SmartingAmp
  class again as was likely originally intended
- Condition variable is used to wait on new samples being available
  so we don't busy-wait the CPU
- Fixed the thread joining
- Fixed several memory leaks
- Channel count is now fixed to 27
- Named the 3 gyro channels
- The driver now remembers the specified COM port
- KB entered COM port selection doesn't now need Enter key
- Removed latency/drift code that looked like adhoc hacks

- Additionally, removed redundant extra copy of the stimulations buffer

- In addition, the TCP Tagging timestamp is now required to be relative
to the computer boot time and hence requires AS and Designer to be on the
same host. If not, server-side stamping should be used.

- ovCTime steady clock is now used for the tagging with 32:32 fixed point time
- The tagging precision can now be sub-millisecond accuracy (not guaranteed)
- If clients provide a non-zero timestamp, this must now be in 32:32 fp as well
- The client provided stamps must be relative to the same point as the server code
  (todo: currently disabled until SDK has an appropriate time getter)
- New flags are provided to request either client or server side tagging. The
  Tag sent over the network will now contain these flags in the first uint64.
- The default is now to put the stamp on client side and adjust on server side.
- The port number is now parsed as an uint32 on the server side, not string
- Simplified the code as allowed by moving to the fixed point time

- On exit, prints the number of timeouts and lost chunks if >0
- Prints a warning on sampling rates exceeding 4800

- Fixed some potential deadlocks and issues in the client thread concurrency control
- Fixed client connection potentially being released before the client thread exit
- Added a warning print if the server doesn't get a steady clock
- Changed pending sample buffer to std::deque for improved
  efficiency on high sampling rates. Updated the plugin interfaces accordingly.
- Removed the truncation of the drift measure to zero, no longer
  needed as the GUI view is less often updated
- Added several sampling rates (including high freqs such as 44100)
  to Generic Oscillator for debugging.
- The server will now clear the pending buffers on pressing 'Stop'.
- Changed some iterator definitions to 'auto' for clarity
- Fixed gcc warnings about %llu and uint64
- Added some comments
- Code cleanup

- AcquisitionServer_StartedDriverSleepDuration parameter is now
  interpreted as follows: <0 == busy wait, 0 == yield, >0 == ms to sleep.
- GUI status is no longer updated more frequently than once per 0.5sec
- Fixed centering of the status lines in the GUI
- Minor code cleanup

- This should not increase CPU load with well-developed hw-based drivers
- Reduces changes that we get drift or jitter due to sleeping
- Drivers based on simulation will have higher CPU loads but less drift
(because they cannot sleep accurately, they have to spin to spend time)

- Made the state texts less ambiguous

- The driver will now return microvolts and a channel name
- Behavior with drift correction disabled should now be fixed

Patch contributed by NeuroServo Inc. and NeurotechX.

Additionally, deprecated several components for clarity,

- Deprecated gUSBamp legacy driver
- Deprecated TMSI Refa32B legacy driver
- Deprecated the Downsampling box
