8add63faa3 Adjust sys.path before importing mmap in demo/python/mmap.py. 
With the previous implementation, `mmap` was importing the demo
script, not the standard `mmap` library module.  From the docs [1]:

  The directory containing the script being run is placed at the
  beginning of the search path, ahead of the standard library
  path. This means that scripts in that directory will be loaded
  instead of modules of the same name in the library directory.

I'm not sure when this changed in Python, since the demo script
presumably worked with an earlier version.

7a277ab0cb Cast the period to an integer in demo/python/cmd.py's command setup. 
This avoids:

  TypeError: in method 'comedi_get_cmd_generic_timed',
    argument 5 of type 'unsigned int'

605fd55655 Fix use of INSN_GTOD so it works on 64-bit platforms. 
A struct timeval is not the same size as a pair of lsampl_t's for 64-bit,
so can't point 'data' in a comedi_insn to a struct timeval and expect it
to work!

c1082cee65 Fixed comedi_get_cmd_generic_timed() by adding a chanlist_len 
parameter.  Old version is still available in library, thanks to the
magic of the version_script.
