Nidaqmx

* Resolved Issues
* [132: __future__ imports are now all mandatory in the minimum supported python version](https://github.com/ni/nidaqmx-python/issues/132)
* Major Changes
* Add support for most NI-DAQmx 16.1-21.5 APIs.
* APIs using time data types are not yet supported.
* Various other improvements:
* No more empty docstrings on constants.
* Fix C API function mapping for attributes - dozens were incorrect.
* Remove some internal-only enumerations that were unused.
* **(compat breaker)** Fix two egregious naming issues when translating the API to `SNAKE_CASE`. `M_HZ` is now
`MHZ` (megahertz) and `<word>m_VOLTS` is now `MILLIVOLTS`.
* **(compat breaker)** Fix various constant names that didn't make any sense.
* Add a header to all auto-generated files indicating that they should not be edited by hand.

* Resolved Issues
* [40: is_task_done() cannot be used.](https://github.com/ni/nidaqmx-python/issues/40)
* [42: register signal event not supported?](https://github.com/ni/nidaqmx-python/issues/42)

* Resolved Issues
* [32: Incorrect types in samp_quant_samp_per_chan and total_samp_per_chan_generated parameters](https://github.com/ni/nidaqmx-python/issues/32)
* [1: nidaqmx doesn't work on Python 2.7.13](https://github.com/ni/nidaqmx-python/issues/1)

* Resolved Issues
* Adding lock around `argtypes` to prevent race condition between setting `argtypes` and calling functions, in cases
the functions run in parallel.
* Some special cases needed unconditional locks around both the setting of `argtypes` and the actual function call,
like the variadic power-up state functions in system.py, and the register events functions in task.py.
